Thank you for considering contributing to BERTopic. With the modular nature of BERTopic, many new add-ons, backends, representation models, sub-models, and LLMs, can quickly be added to keep up with the incredibly fast-pacing field. + +Whether contributions are new features, better documentation, bug fixes, or improvement on the repository itself, anything is appreciated! + +## πŸ“š Guidelines + +### πŸ€– Contributing Code + +To contribute to this project, we follow an `issue -> pull request` approach for main features and bug fixes. This means that any new feature, bug fix, or anything else that touches on code directly needs to start from an issue first. That way, the main discussion about what needs to be added/fixed can be done in the issue before creating a pull request. This makes sure that we are on the same page before you start coding your pull request. If you start working on an issue, please assign it to yourself but do so after there is an agreement with the maintainer, [@MaartenGr](https://github.com/MaartenGr). + +When there is agreement on the assigned approach, a pull request can be created in which the fix/feature can be added. This follows a ["fork and pull request"](https://docs.github.com/en/get-started/quickstart/contributing-to-projects) workflow. +Please do not try to push directly to this repo unless you are a maintainer. + +There are exceptions to the `issue -> pull request` approach that are typically small changes that do not need agreements, such as: +* Documentation +* Spelling/grammar issues +* Docstrings +* etc. + +There is a large focus on documentation in this repository, so please make sure to add extensive descriptions of features when creating the pull request. + +Note that the main focus of pull requests and code should be: +* Easy readability +* Clear communication +* Sufficient documentation + +## πŸš€ Quick Start + +To start contributing, make sure to first start from a fresh environment. Using an environment manager, such as `conda` or `pyenv` helps in making sure that your code is reproducible and tracks the versions you have in your environment. + +If you are using conda, you can approach it as follows: + +1. Create and activate a new conda environment (e.g., `conda create -n bertopic python=3.9`) +2. Install requirements (e.g., `pip install .[dev]`) + * This makes sure to also install documentation and testing packages +3. (Optional) Run `make docs` to build your documentation +4. (Optional) Run `make test` to run the unit tests and `make coverage` to check the coverage of unit tests + +❗Note: Unit testing the package can take quite some time since it needs to run several variants of the BERTopic pipeline. + +## πŸ€“ Collaborative Efforts + +When you run into any issue with the above or need help to start with a pull request, feel free to reach out in the issues! As with all repositories, this one has its particularities as a result of the maintainer's view. Each repository is quite different and so will their processes. + +## πŸ† Recognition + +If your contribution has made its way into a new release of BERTopic, you will be given credit in the changelog of the new release! Regardless of the size of the contribution, any help is greatly appreciated. + +## 🎈 Release + +BERTopic tries to mostly follow [semantic versioning](https://semver.org/) for its new releases. Even though BERTopic has been around for a few years now, it is still pre-1.0 software. With the rapid chances in the field and as a way to keep up, this versioning is on purpose. Backwards-compatibility is taken into account but integrating new features and thereby keeping up with the field takes priority. Especially since BERTopic focuses on modularity, flexibility is necessary. diff --git a/BERTopic/.github/workflows/testing.yml b/BERTopic/.github/workflows/testing.yml new file mode 100644 index 0000000000000000000000000000000000000000..1467270d33efc499c18be24e8fc272909edb18e1 --- /dev/null +++ b/BERTopic/.github/workflows/testing.yml @@ -0,0 +1,31 @@ +name: Code Checks + +on: + push: + branches: + - master + - dev + pull_request: + branches: + - master + - dev + +jobs: + build: + runs-on: ubuntu-latest + strategy: + matrix: + python-version: [3.8, 3.9] + + steps: + - uses: actions/checkout@v2 + - name: Set up Python ${{ matrix.python-version }} + uses: actions/setup-python@v1 + with: + python-version: ${{ matrix.python-version }} + - name: Install dependencies + run: | + python -m pip install --upgrade pip + pip install -e ".[test]" + - name: Run Checking Mechanisms + run: make check diff --git a/BERTopic/.gitignore b/BERTopic/.gitignore new file mode 100644 index 0000000000000000000000000000000000000000..e526ce54690e987e0067ae0fbb16a58c9c989817 --- /dev/null +++ b/BERTopic/.gitignore @@ -0,0 +1,83 @@ +# Byte-compiled / optimized / DLL files +__pycache__/ +*.py[cod] +*$py.class + +# C extensions +*.so + +# Distribution / packaging +.Python +build/ +develop-eggs/ +dist/ +downloads/ +eggs/ +.eggs/ +lib/ +lib64/ +parts/ +sdist/ +var/ +wheels/ +pip-wheel-metadata/ +share/python-wheels/ +*.egg-info/ +.installed.cfg +*.egg +MANIFEST +model_dir +model_dir/ +test + +# PyInstaller +# Usually these files are written by a python script from a template +# before PyInstaller builds the exe, so as to inject date/other infos into it. +*.manifest +*.spec + +# Installer logs +pip-log.txt +pip-delete-this-directory.txt + +# Unit test / coverage reports +htmlcov/ +.tox/ +.nox/ +.coverage +.coverage.* +.cache +nosetests.xml +coverage.xml +*.cover +.hypothesis/ +.pytest_cache/ + +# Sphinx documentation +docs/_build/ + + +# Jupyter Notebook +.ipynb_checkpoints + +# IPython +profile_default/ +ipython_config.py + +# pyenv +.python-version + +# Environments +.env +.venv +env/ +venv/ +ENV/ +env.bak/ +venv.bak/ + +# Artifacts +.idea +.idea/ +.vscode +.DS_Store diff --git a/BERTopic/LICENSE b/BERTopic/LICENSE new file mode 100644 index 0000000000000000000000000000000000000000..6bd3f0517e606b3ceeba1c80c347e58c97255e79 --- /dev/null +++ b/BERTopic/LICENSE @@ -0,0 +1,21 @@ +MIT License + +Copyright (c) 2023, Maarten P.

Each word in a topic describes the underlying theme of that topic and can be used +for interpreting that topic. Next, let's take a look at the most frequent topic that was generated: + +```python +>>> topic_model.get_topic(0) + +[('windows', 0.006152228076250982), + ('drive', 0.004982897610645755), + ('dos', 0.004845038866360651), + ('file', 0.004140142872194834), + ('disk', 0.004131678774810884), + ('mac', 0.003624848635985097), + ('memory', 0.0034840976976789903), + ('software', 0.0034415334250699077), + ('email', 0.0034239554442333257), + ('pc', 0.003047105930670237)] +``` + +Using `.get_document_info`, we can also extract information on a document level, such as their corresponding topics, probabilities, whether they are representative documents for a topic, etc.: + +```python +>>> topic_model.get_document_info(docs) + +Document Topic Name Top_n_words Probability ... +I am sure some bashers of Pens... 0 0_game_team_games_season game - team - games... 0.200010 ... +My brother is in the market for... -1 -1_can_your_will_any can - your - will... 0.420668 ... +Finally you said what you dream... -1 -1_can_your_will_any can - your - will... 0.807259 ... +Think!

They are all quite different from one another and give interesting perspectives and variations of topic representations. A great start is `KeyBERTInspired`, which for many users increases the coherence and reduces stopwords from the resulting topic representations: + + ```python +from bertopic.representation import KeyBERTInspired + +# Fine-tune your topic representations +representation_model = KeyBERTInspired() +topic_model = BERTopic(representation_model=representation_model) +``` + +However, you might want to use something more powerful to describe your clusters. You can even use ChatGPT or other models from OpenAI to generate labels, summaries, phrases, keywords, and more: + +```python +import openai +from bertopic.representation import OpenAI + +# Fine-tune topic representations with GPT +client = openai.OpenAI(api_key="sk-...") +representation_model = OpenAI(client, model="gpt-3.5-turbo", chat=True) +topic_model = BERTopic(representation_model=representation_model) +``` + +**`πŸ”₯ Tip`**: Instead of iterating over all of these different topic representations, you can model them simultaneously with [multi-aspect topic representations](https://maartengr.github.io/BERTopic/getting_started/multiaspect/multiaspect.html) in BERTopic. + + +## Visualizations +After having trained our BERTopic model, we can iteratively go through hundreds of topics to get a good +understanding of the topics that were extracted. However, that takes quite some time and lacks a global representation. Instead, we can use one of the [many visualization options](https://maartengr.github.io/BERTopic/getting_started/visualization/visualization.html) in BERTopic. +For example, we can visualize the topics that were generated in a way very similar to +[LDAvis](https://github.com/cpsievert/LDAvis): + +```python +topic_model.visualize_topics() +``` + + + +## Modularity +By default, the [main steps](https://maartengr.github.io/BERTopic/algorithm/algorithm.html) for topic modeling with BERTopic are sentence-transformers, UMAP, HDBSCAN, and c-TF-IDF run in sequence. However, it assumes some independence between these steps which makes BERTopic quite modular. In other words, BERTopic not only allows you to build your own topic model but to explore several topic modeling techniques on top of your customized topic model: + +https://user-images.githubusercontent.com/25746895/218420473-4b2bb539-9dbe-407a-9674-a8317c7fb3bf.mp4 + +You can swap out any of these models or even remove them entirely.

Embed documents** +We start by converting our documents to numerical representations. Although there are many methods for doing so the default in BERTopic is [sentence-transformers](https://github.com/UKPLab/sentence-transformers). These models are often optimized for semantic similarity which helps tremendously in our clustering task. Moreover, they are great for creating either document- or sentence-embeddings. +
+In BERTopic, you can choose any sentence-transformers model but two models are set as defaults: + +* `"all-MiniLM-L6-v2"` +* `"paraphrase-multilingual-MiniLM-L12-v2"` + +The first is an English language model trained specifically for semantic similarity tasks which works quite +well for most use cases. The second model is very similar to the first with one major difference being that the +`multilingual` models work for 50+ languages. This model is quite a bit larger than the first and is only selected if +you select any language other than English. + +!!! tip Embedding models + + Although BERTopic uses sentence-transformers models as a default, you can choose + any embedding model that fits your use case. Follow the guide [here](https://maartengr.github.io/BERTopic/getting_started/embeddings/embeddings.html) for selecting + and customizing your model. + + +### **2. Dimensionality reduction** +After having created our numerical representations of the documents we have to reduce the dimensionality of these representations. Cluster models typically have difficulty handling high dimensional data due to the curse of dimensionality. There are great approaches that can reduce dimensionality, such as PCA, but as a default [UMAP](https://github.com/lmcinnes/umap) is selected in BERTopic. It is a technique that can keep some of a dataset's local and global structure when reducing its dimensionality. This structure is important to keep as it contains the information necessary to create clusters of semantically similar documents. + +!!! tip Dimensionality reduction models + + Although BERTopic uses UMAP as a default, you can choose + any dimensionality reduction model that fits your use case. Follow the guide [here](https://maartengr.github.io/BERTopic/getting_started/dim_reduction/dim_reduction.html) for selecting + and customizing your model. + +### **3. Cluster Documents** +After having reduced our embeddings, we can start clustering our data. For that, we leverage a density-based clustering technique, HDBSCAN. It can find clusters of different shapes and has the nice feature of identifying outliers where possible. As a result, we do not force documents into a cluster where they might not belong. This will improve the resulting topic representation as there is less noise to draw from. + +!!! tip Cluster models + + Although BERTopic uses HDBSCAN as a default, you can choose + any cluster model that fits your use case. Follow the guide [here](https://maartengr.github.io/BERTopic/getting_started/clustering/clustering.html) for selecting + and customizing your model. + +### **4. Bag-of-words** +Before we can start creating the topic representation we first need to select a technique that allows for modularity in BERTopic's algorithm. When we use HDBSCAN as a cluster model, we may assume that our clusters have different degrees of density and different shapes. This means that a centroid-based topic representation technique might not be the best-fitting model. In other words, we want a topic representation technique that makes little to no assumption on the expected structure of the clusters. +
+To do this, we first combine all documents in a cluster into a single document. That, very long, document then represents the cluster. Then, we can count how often each word appears in each cluster. This generates something called a bag-of-words representation in which the frequency of each word in each cluster can be found. This bag-of-words representation is therefore on a cluster level and not on a document level. This distinction is important as we are interested in words on a topic level (i.e., cluster level). By using a bag-of-words representation, no assumption is made concerning the structure of the clusters. Moreover, the bag-of-words representation is L1-normalized to account for clusters that have different sizes. + +!!! tip Bag-of-words and tokenization + + There are many ways you can tune or change the bag-of-words step. This step allows for processing the documents however you want without affecting the first step, embedding the documents. You can follow the guide [here](https://maartengr.github.io/BERTopic/getting_started/vectorizers/vectorizers.html) for more information about tokenization options in BERTopic. + +### **5. Topic representation** +From the generated bag-of-words representation, we want to know what makes one cluster different from another. Which words are typical for cluster 1 and not so much for all other clusters? To solve this, we need to modify TF-IDF such that it considers topics (i.e., clusters) instead of documents. +
+When you apply TF-IDF as usual on a set of documents, what you are doing is comparing the importance of +words between documents. Now, what if, we instead treat all documents in a single category (e.g., a cluster) as a single document and then apply TF-IDF? The result would be importance scores for words within a cluster. The more important words are within a cluster, the more it is representative of that topic. In other words, if we extract the most important words per cluster, we get descriptions of **topics**! This model is called **class-based TF-IDF**: +

+ + + +
+Each cluster is converted to a single document instead of a set of documents. Then, we extract the frequency of word `x` in class `c`, where `c` refers to the cluster we created before. This results in our class-based `tf` representation. This representation is L1-normalized to account for the differences in topic sizes. +

+Then, we take the logarithm of one plus the average number of words per class `A` divided by the frequency of word `x` across all classes. We add plus one within the logarithm to force values to be positive. This results in our class-based `idf` representation. Like with the classic TF-IDF, we then multiply `tf` with `idf` to get the importance score per word in each class. In other words, the classical TF-IDF procedure is **not** used here but a modified version of the algorithm that allows for a much better representation. + +!!! tip c-TF-IDF parameters + + In the `ClassTfidfTransformer`, there are a few parameters that might be worth exploring, including an option to perform additional BM-25 weighting. You can find more information about that [here](https://maartengr.github.io/BERTopic/getting_started/ctfidf/ctfidf.html). + +### **6. (Optional) Fine-tune Topic representation** +After having generated the c-TF-IDF representations, we have a set of words that describe a collection of documents. c-TF-IDF +is a method that can quickly generate accurate topic representations. However, with the fast developments in NLP-world, new +and exciting methods are released weekly. In order to keep up with what is happening, there is the possibility to further fine-tune +these c-TF-IDF topics using GPT, T5, KeyBERT, Spacy, and other techniques. Many are implemented in BERTopic for you to use and play around with. + +More specifically, we can consider the c-TF-IDF generated topics to be candidate topics. They each contain a set of keywords and +representative documents that we can use to further fine-tune the topic representations. Having a set of representative documents +for each topic is huge advantage as it allows for fine-tuning on a reduced number of documents. This reduces computation for +large models as they only need to operate on that small set of representative documents for each topic. As a result, +large language models like GPT and T5 becomes feasible in production settings and typically take less wall time than the dimensionality reduction +and clustering steps. + +The following models are implemented in `bertopic.representation`: + +* `MaximalMarginalRelevance` +* `PartOfSpeech` +* `KeyBERTInspired` +* `ZeroShotClassification` +* `TextGeneration` +* `Cohere` +* `OpenAI` +*

Merge Pre-trained BERTopic Models

+ +The new `.merge_models` feature allows for any number of fitted BERTopic models to be merged. Doing so allows for a number of use cases: + +* **Incremental topic modeling** -- Continuously merge models together to detect whether new topics have appeared +* **Federated Learning** - Train BERTopic models on different clients and combine them on a central server +* **Minimal compute** - We can essentially batch the training process into multiple instances to reduce compute +* **Different datasets** - When you have different datasets that you want to train separately on, for example with different languages, you can train each model separately and join them after training + +To demonstrate merging different topic models with BERTopic, we use the ArXiv paper abstracts to see which topics they generally contain. + +First, we train three separate models on different parts of the data: + +```python +from umap import UMAP +from bertopic import BERTopic +from datasets import load_dataset + +dataset = load_dataset("CShorten/ML-ArXiv-Papers")["train"] + +# Extract abstracts to train on and corresponding titles +abstracts_1 = dataset["abstract"][:5_000] +abstracts_2 = dataset["abstract"][5_000:10_000] +abstracts_3 = dataset["abstract"][10_000:15_000] + +# Create topic models +umap_model = UMAP(n_neighbors=15, n_components=5, min_dist=0.0, metric='cosine', random_state=42) +topic_model_1 = BERTopic(umap_model=umap_model, min_topic_size=20).fit(abstracts_1) +topic_model_2 = BERTopic(umap_model=umap_model, min_topic_size=20).fit(abstracts_2) +topic_model_3 = BERTopic(umap_model=umap_model, min_topic_size=20).fit(abstracts_3) +``` + +Then, we can combine all three models into one with `.merge_models`: + +```python +# Combine all models into one +merged_model = BERTopic.merge_models([topic_model_1, topic_model_2, topic_model_3]) +``` + +

Zero-shot Topic Modeling

+Zeroshot Topic Modeling is a technique that allows you to find pre-defined topics in large amounts of documents. This method allows you to not only find those specific topics but also create new topics for documents that would not fit with your predefined topics. +This allows for extensive flexibility as there are three scenario's to explore. + +* No zeroshot topics were detected. This means that none of the documents would fit with the predefined topics and a regular BERTopic would be run. +* Only zeroshot topics were detected. Here, we would not need to find additional topics since all original documents were assigned to one of the predefined topics. +* Both zeroshot topics and clustered topics were detected. This means that some documents would fit with the predefined topics where others would not. For the latter, new topics were found. + +![zeroshot](https://github.com/MaartenGr/BERTopic/assets/25746895/9cce6ee3-445f-440a-b93b-f8008578c839) + +In order to use zero-shot BERTopic, we create a list of topics that we want to assign to our documents. However, +there may be several other topics that we know should be in the documents. The dataset that we use is small subset of ArXiv papers. +We know the data and believe there to be at least the following topics: *clustering*, *topic modeling*, and *large language models*. +However, we are not sure whether other topics exist and want to explore those. + +Using this feature is straightforward: + +```python +from datasets import load_dataset + +from bertopic import BERTopic +from bertopic.representation import KeyBERTInspired + +# We select a subsample of 5000 abstracts from ArXiv +dataset = load_dataset("CShorten/ML-ArXiv-Papers")["train"] +docs = dataset["abstract"][:5_000] + +# We define a number of topics that we know are in the documents +zeroshot_topic_list = ["Clustering", "Topic Modeling", "Large Language Models"] + +# We fit our model using the zero-shot topics +# and we define a minimum similarity. For each document, +# if the similarity does not exceed that value, it will be used +# for clustering instead. +topic_model = BERTopic( + embedding_model="thenlper/gte-small", + min_topic_size=15, + zeroshot_topic_list=zeroshot_topic_list, + zeroshot_min_similarity=.85, + representation_model=KeyBERTInspired() +) +topics, _ = topic_model.fit_transform(docs) +``` + +When we run `topic_model.get_topic_info()` you will see something like this: + +![zeroshot_output](https://github.com/MaartenGr/BERTopic/assets/25746895/1801e0a9-cda7-4d74-929f-e975fa67404b) + +

Seed (Domain-specific) Words

+ + +When performing Topic Modeling, you are often faced with data that you are familiar with to a certain extend or that speaks a very specific language. In those cases, topic modeling techniques might have difficulties capturing and representing the semantic nature of domain specific abbreviations, slang, short form, acronyms, etc. For example, the *"TNM"* classification is a method for identifying the stage of most cancers. The word *"TNM"* is an abbreviation and might not be correctly captured in generic embedding models. + +To make sure that certain domain specific words are weighted higher and are more often used in topic representations, you can set any number of `seed_words` in the `bertopic.vectorizer.ClassTfidfTransformer`. To do so, let's take a look at an example. We have a dataset of article abstracts and want to perform some topic modeling. Since we might be familiar with the data, there are certain words that we know should be generally important. Let's assume that we have in-depth knowledge about reinforcement learning and know that words like "agent" and "robot" should be important in such a topic were it to be found. Using the `ClassTfidfTransformer`, we can define those `seed_words` and also choose by how much their values are multiplied. + +The full example is then as follows: + +```python +from umap import UMAP +from datasets import load_dataset +from bertopic import BERTopic +from bertopic.vectorizers import ClassTfidfTransformer + +# Let's take a subset of ArXiv abstracts as the training data +dataset = load_dataset("CShorten/ML-ArXiv-Papers")["train"] +abstracts = dataset["abstract"][:5_000] + +# For illustration purposes, we make sure the output is fixed when running this code multiple times +umap_model = UMAP(n_neighbors=15, n_components=5, min_dist=0.0, metric='cosine', random_state=42) + +# We can choose any number of seed words for which we want their representation +# to be strengthen. We increase the importance of these words as we want them to be more +# likely to end up in the topic representations. +ctfidf_model = ClassTfidfTransformer( + seed_words=["agent", "robot", "behavior", "policies", "environment"], + seed_multiplier=2 +) + +# We run the topic model with the seeded words +topic_model = BERTopic( + umap_model=umap_model, + min_topic_size=15, + ctfidf_model=ctfidf_model, +).fit(abstracts) +``` + +

Truncate Documents in LLMs

+ +When using LLMs with BERTopic, we can truncate the input documents in `[DOCUMENTS]` in order to reduce the number of tokens that we have in our input prompt. To do so, all text generation modules have two parameters that we can tweak: + +* `doc_length` - The maximum length of each document. If a document is longer, it will be truncated. If None, the entire document is passed. +* `tokenizer` - The tokenizer used to calculate to split the document into segments used to count the length of a document. + * Options include `'char'`, `'whitespace'`, `'vectorizer'`, and a callable + +This means that the definition of `doc_length` changes depending on what constitutes a token in the `tokenizer` parameter. If a token is a character, then `doc_length` refers to max length in characters. If a token is a word, then `doc_length` refers to the max length in words. + +Let's illustrate this with an example. In the code below, we will use [`tiktoken`](https://github.com/openai/tiktoken) to count the number of tokens in each document and limit them to 100 tokens. All documents that have more than 100 tokens will be truncated. + +We use `bertopic.representation.OpenAI` to represent our topics with nicely written labels. We specify that documents that we put in the prompt cannot exceed 100 tokens each. Since we will put 4 documents in the prompt, they will total roughly 400 tokens: + +```python +import openai +import tiktoken +from bertopic.representation import OpenAI +from bertopic import BERTopic + +# Tokenizer +tokenizer= tiktoken.encoding_for_model("gpt-3.5-turbo") + +# Create your representation model +client = openai.OpenAI(api_key="sk-...") +representation_model = OpenAI( + client, + model="gpt-3.5-turbo", + delay_in_seconds=2, + chat=True, + nr_docs=4, + doc_length=100, + tokenizer=tokenizer +) + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + + +## **Version 0.15.0** +*Release date: 29 May, 2023* + +

Multimodal Topic Modeling

+ +With v0.15, we can now perform multimodal topic modeling in BERTopic! The most basic example of multimodal topic modeling in BERTopic is when you have images that accompany your documents. This means that it is expected that each document has an image and vice versa. Instagram pictures, for example, almost always have some descriptions to them. + +
+ ![Image title](getting_started/multimodal/images_and_text.svg) +
+
+ +In this example, we are going to use images from `flickr` that each have a caption accociated to it: + +```python +# NOTE: This requires the `datasets` package which you can +# install with `pip install datasets` +from datasets import load_dataset + +ds = load_dataset("maderix/flickr_bw_rgb") +images = ds["train"]["image"] +docs = ds["train"]["caption"] +``` + +The `docs` variable contains the captions for each image in `images`. We can now use these variables to run our multimodal example: + +```python +from bertopic import BERTopic +from bertopic.representation import VisualRepresentation + +# Additional ways of representing a topic +visual_model = VisualRepresentation() + +# Make sure to add the `visual_model` to a dictionary +representation_model = { + "Visual_Aspect": visual_model, +} +topic_model = BERTopic(representation_model=representation_model, verbose=True) +``` + +We can now access our image representations for each topic with `topic_model.topic_aspects_["Visual_Aspect"]`. +If you want an overview of the topic images together with their textual representations in jupyter, you can run the following: + +```python +import base64 +from io import BytesIO +from IPython.display import HTML + +def image_base64(im): + if isinstance(im, str): + im = get_thumbnail(im) + with BytesIO() as buffer: + im.save(buffer, 'jpeg') + return base64.b64encode(buffer.getvalue()).decode() + + +def image_formatter(im): + return f'' + +# Extract dataframe +df = topic_model.get_topic_info().drop("Representative_Docs", 1).drop("Name", 1) + +# Visualize the images +HTML(df.to_html(formatters={'Visual_Aspect': image_formatter}, escape=False)) +``` + +![images_and_text](https://github.com/MaartenGr/BERTopic/assets/25746895/3a741e2b-5810-4865-9664-0c6bb24ca3f9) + + +

Multi-aspect Topic Modeling

+ +In this new release, we introduce `multi-aspect topic modeling`! During the `.fit` or `.fit_transform` stages, you can now get multiple representations of a single topic. In practice, it works by generating and storing all kinds of different topic representations (see image below). + +
+ ![Image title](getting_started/multiaspect/multiaspect.svg) +
+
+ +The approach is rather straightforward. We might want to represent our topics using a `PartOfSpeech` representation model but we might also want to try out `KeyBERTInspired` and compare those representation models. We can do this as follows: + +```python +from bertopic.representation import KeyBERTInspired +from bertopic.representation import PartOfSpeech +from bertopic.representation import MaximalMarginalRelevance +from sklearn.datasets import fetch_20newsgroups + +# Documents to train on +docs = fetch_20newsgroups(subset='all', remove=('headers', 'footers', 'quotes'))['data'] + +# The main representation of a topic +main_representation = KeyBERTInspired() + +# Additional ways of representing a topic +aspect_model1 = PartOfSpeech("en_core_web_sm") +aspect_model2 = [KeyBERTInspired(top_n_words=30), MaximalMarginalRelevance(diversity=.5)] + +# Add all models together to be run in a single `fit` +representation_model = { + "Main": main_representation, + "Aspect1": aspect_model1, + "Aspect2": aspect_model2 +} +topic_model = BERTopic(representation_model=representation_model).fit(docs) +``` + +As show above, to perform multi-aspect topic modeling, we make sure that `representation_model` is a dictionary where each representation model pipeline is defined. +The main pipeline, that is used in most visualization options, is defined with the `"Main"` key. All other aspects can be defined however you want. In the example above, the two additional aspects that we are interested in are defined as `"Aspect1"` and `"Aspect2"`. + +After we have fitted our model, we can access all representations with `topic_model.get_topic_info()`: + + +
+ +As you can see, there are a number of different representations for our topics that we can inspect. All aspects are found in `topic_model.topic_aspects_`. + + +

Serialization

+ +Saving, loading, and sharing a BERTopic model can be done in several ways. With this new release, it is now advised to go with `.safetensors` as that allows for a small, safe, and fast method for saving your BERTopic model. However, other formats, such as `.pickle` and pytorch `.bin` are also possible. + +The methods are used as follows: + +```python +topic_model = BERTopic().fit(my_docs) + +# Method 1 - safetensors +embedding_model = "sentence-transformers/all-MiniLM-L6-v2" +topic_model.save("path/to/my/model_dir", serialization="safetensors", save_ctfidf=True, save_embedding_model=embedding_model) + +# Method 2 - pytorch +embedding_model = "sentence-transformers/all-MiniLM-L6-v2" +topic_model.save("path/to/my/model_dir", serialization="pytorch", save_ctfidf=True, save_embedding_model=embedding_model) + +# Method 3 - pickle +topic_model.save("my_model", serialization="pickle") +``` + +Saving the topic modeling with `.safetensors` or `pytorch` has a number of advantages: + +* `.safetensors` is a relatively **safe format** +* The resulting model can be **very small** (often < 20MB>) since no sub-models need to be saved +* Although version control is important, there is a bit more **flexibility** with respect to specific versions of packages +* More easily used in **production** +* **Share** models with the HuggingFace Hub + +

+ +

+ +The above image, a model trained on 100,000 documents, demonstrates the differences in sizes comparing `safetensors`, `pytorch`, and `pickle`. The difference in sizes can mostly be explained due to the efficient saving procedure and that the clustering and dimensionality reductions are not saved in safetensors/pytorch since inference can be done based on the topic embeddings. + + + + +

HuggingFace Hub

+ +When you have created a BERTopic model, you can easily share it with other through the HuggingFace Hub. First, you need to log in to your HuggingFace account: + +```python +from huggingface_hub import login +login() +``` + +When you have logged in to your HuggingFace account, you can save and upload the model as follows: + +```python +from bertopic import BERTopic + +# Train model +topic_model = BERTopic().fit(my_docs) + +# Push to HuggingFace Hub +topic_model.push_to_hf_hub( + repo_id="MaartenGr/BERTopic_ArXiv", + save_ctfidf=True +) + +# Load from HuggingFace +loaded_model = BERTopic.load("MaartenGr/BERTopic_ArXiv") +``` + +## **Version 0.14.1** +*Release date: 2 March, 2023* + +

Highlights:

+ +* Use [**ChatGPT**](https://maartengr.github.io/BERTopic/getting_started/representation/representation.html#chatgpt) to create topic representations!: +* Added `delay_in_seconds` parameter to OpenAI and Cohere representation models for throttling the API + * Setting this between 5 and 10 allows for trial users now to use more easily without hitting RateLimitErrors +* Fixed missing `title` param to visualization methods +* Fixed probabilities not correctly aligning ([#1024](https://github.com/MaartenGr/BERTopic/issues/1024)) +* Fix typo in textgenerator [@dkopljar27](https://github.com/dkopljar27) in [#1002](https://github.com/MaartenGr/BERTopic/pull/1002) + +

ChatGPT

+ +Within OpenAI's API, the ChatGPT models use a different API structure compared to the GPT-3 models. +In order to use ChatGPT with BERTopic, we need to define the model and make sure to set `chat=True`: + +```python +import openai +from bertopic import BERTopic +from bertopic.representation import OpenAI + +# Create your representation model +openai.api_key = MY_API_KEY +representation_model = OpenAI(model="gpt-3.5-turbo", delay_in_seconds=10, chat=True) + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +Prompting with ChatGPT is very satisfying and can be customized in BERTopic by using certain tags. +There are currently two tags, namely `"[KEYWORDS]"` and `"[DOCUMENTS]"`. +These tags indicate where in the prompt they are to be replaced with a topics keywords and top 4 most representative documents respectively. +For example, if we have the following prompt: + +```python +prompt = """ +I have topic that contains the following documents: \n[DOCUMENTS] +The topic is described by the following keywords: [KEYWORDS] + +Based on the information above, extract a short topic label in the following format: +topic: +""" +``` + +then that will be rendered as follows and passed to OpenAI's API: + +```python +""" +I have a topic that contains the following documents: +- Our videos are also made possible by your support on patreon.co. +- If you want to help us make more videos, you can do so on patreon.com or get one of our posters from our shop. +- If you want to help us make more videos, you can do so there. +- And if you want to support us in our endeavor to survive in the world of online video, and make more videos, you can do so on patreon.com. + +The topic is described by the following keywords: videos video you our support want this us channel patreon make on we if facebook to patreoncom can for and more watch + +Based on the information above, extract a short topic label in the following format: +topic: +""" +``` + +!!! note + Whenever you create a custom prompt, it is important to add + ``` + Based on the information above, extract a short topic label in the following format: + topic: + ``` + at the end of your prompt as BERTopic extracts everything that comes after `topic: `. Having + said that, if `topic: ` is not in the output, then it will simply extract the entire response, so + feel free to experiment with the prompts. + + +## **Version 0.14.0** +*Release date: 14 February, 2023* + +

Representation Models

+ +Fine-tune the c-TF-IDF representation with a variety of models. Whether that is through a KeyBERT-Inspired model or GPT-3, the choice is up to you! + + + +
+ + +

KeyBERTInspired

+ +The algorithm follows some principles of [KeyBERT](https://github.com/MaartenGr/KeyBERT) but does some optimization in order to speed up inference. Usage is straightforward: + +![keybertinspired](https://user-images.githubusercontent.com/25746895/216336376-d2c4e5d6-6cf7-435c-904c-fc195aae7dcd.svg) + +```python +from bertopic.representation import KeyBERTInspired +from bertopic import BERTopic + +# Create your representation model +representation_model = KeyBERTInspired() + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +![keybert](https://user-images.githubusercontent.com/25746895/218417161-bfd5980e-43c7-498a-904a-b6018ba58d45.svg) + +

PartOfSpeech

+ +Our candidate topics, as extracted with c-TF-IDF, do not take into account a keyword's part of speech as extracting noun-phrases from all documents can be computationally quite expensive. Instead, we can leverage c-TF-IDF to perform part of speech on a subset of keywords and documents that best represent a topic. + +![partofspeech](https://user-images.githubusercontent.com/25746895/216336534-48ff400e-72e1-4c50-9030-414576bac01e.svg) + + +```python +from bertopic.representation import PartOfSpeech +from bertopic import BERTopic + +# Create your representation model +representation_model = PartOfSpeech("en_core_web_sm") + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +![pos](https://user-images.githubusercontent.com/25746895/218417198-41c19b5c-251f-43c1-bfe2-0a480731565a.svg) + + +

MaximalMarginalRelevance

+ +When we calculate the weights of keywords, we typically do not consider whether we already have similar keywords in our topic. Words like "car" and "cars" +essentially represent the same information and often redundant. We can use `MaximalMarginalRelevance` to improve diversity of our candidate topics: + +![mmr](https://user-images.githubusercontent.com/25746895/216336697-558f1409-8da3-4076-a21b-d87eec583ac7.svg) + + +```python +from bertopic.representation import MaximalMarginalRelevance +from bertopic import BERTopic + +# Create your representation model +representation_model = MaximalMarginalRelevance(diversity=0.3) + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +![mmr (1)](https://user-images.githubusercontent.com/25746895/218417234-88b145e2-7293-43c0-888c-36abe469a48a.svg) + +

Zero-Shot Classification

+ +To perform zero-shot classification, we feed the model with the keywords as generated through c-TF-IDF and a set of candidate labels. If, for a certain topic, we find a similar enough label, then it is assigned. If not, then we keep the original c-TF-IDF keywords. + +We use it in BERTopic as follows: + +```python +from bertopic.representation import ZeroShotClassification +from bertopic import BERTopic + +# Create your representation model +candidate_topics = ["space and nasa", "bicycles", "sports"] +representation_model = ZeroShotClassification(candidate_topics, model="facebook/bart-large-mnli") + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +![zero](https://user-images.githubusercontent.com/25746895/218417276-dcef3519-acba-4792-8601-45dc7ed39488.svg) + +

Text Generation: πŸ€— Transformers

+ +Nearly every week, there are new and improved models released on the πŸ€— [Model Hub](https://huggingface.co/models) that, with some creativity, allow for +further fine-tuning of our c-TF-IDF based topics. These models range from text generation to zero-classification. In BERTopic, wrappers around these +methods are created as a way to support whatever might be released in the future. + +Using a GPT-like model from the huggingface hub is rather straightforward: + +```python +from bertopic.representation import TextGeneration +from bertopic import BERTopic + +# Create your representation model +representation_model = TextGeneration('gpt2') + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +![hf](https://user-images.githubusercontent.com/25746895/218417310-2b0eabc7-296d-499d-888b-0ab48a65a2fb.svg) + + +

Text Generation: Cohere

+ +Instead of using a language model from πŸ€— transformers, we can use external APIs instead that +do the work for you. Here, we can use [Cohere](https://docs.cohere.ai/) to extract our topic labels from the candidate documents and keywords. +To use this, you will need to install cohere first: + +```bash +pip install cohere +``` + +Then, get yourself an API key and use Cohere's API as follows: + +```python +import cohere +from bertopic.representation import Cohere +from bertopic import BERTopic + +# Create your representation model +co = cohere.Client(my_api_key) +representation_model = Cohere(co) + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +![cohere](https://user-images.githubusercontent.com/25746895/218417337-294cb52a-93c9-4fd5-b981-29b40e4f0c1e.svg) + + +

Text Generation: OpenAI

+ +Instead of using a language model from πŸ€— transformers, we can use external APIs instead that +do the work for you. Here, we can use [OpenAI](https://openai.com/api/) to extract our topic labels from the candidate documents and keywords. +To use this, you will need to install openai first: + +``` +pip install openai +``` + +Then, get yourself an API key and use OpenAI's API as follows: + +```python +import openai +from bertopic.representation import OpenAI +from bertopic import BERTopic + +# Create your representation model +openai.api_key = MY_API_KEY +representation_model = OpenAI() + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +![openai](https://user-images.githubusercontent.com/25746895/218417357-cf8c0fab-4450-43d3-b4fd-219ed276d870.svg) + + +

Text Generation: LangChain

+ +[Langchain](https://github.com/hwchase17/langchain) is a package that helps users with chaining large language models. +In BERTopic, we can leverage this package in order to more efficiently combine external knowledge. Here, this +external knowledge are the most representative documents in each topic. + +To use langchain, you will need to install the langchain package first. Additionally, you will need an underlying LLM to support langchain, +like openai: + +```bash +pip install langchain, openai +``` + +Then, you can create your chain as follows: + +```python +from langchain.chains.question_answering import load_qa_chain +from langchain.llms import OpenAI +chain = load_qa_chain(OpenAI(temperature=0, openai_api_key=MY_API_KEY), chain_type="stuff") +``` + +Finally, you can pass the chain to BERTopic as follows: + +```python +from bertopic.representation import LangChain + +# Create your representation model +representation_model = LangChain(chain) + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + + +## **Version 0.13.0** +*Release date: 4 January, 2023* + +

Documentation

+ +Personally, I believe that documentation can be seen as a feature and is an often underestimated aspect of open-source. So I went a bit overboardπŸ˜…... and created an animation about the three pillars of BERTopic using Manim. There are many other visualizations added, one of each variation of BERTopic, and many smaller changes. + + + +

Topic Distributions

+ +The difficulty with a cluster-based topic modeling technique is that it does not directly consider that documents may contain multiple topics. With the new release, we can now model the distributions of topics! We even consider that a single word might be related to multiple topics. If a document is a mixture of topics, what is preventing a single word to be the same? + +To do so, we approximate the distribution of topics in a document by calculating and summing the similarities of tokensets (achieved by applying a sliding window) with the topics: + +```python +# After fitting your model run the following for either your trained documents or even unseen documents +topic_distr, _ = topic_model.approximate_distribution(docs) +``` + +To calculate and visualize the topic distributions in a document on a token-level, we can run the following: + +```python +# We need to calculate the topic distributions on a token level +topic_distr, topic_token_distr = topic_model.approximate_distribution(docs, calculate_tokens=True) + +# Create a visualization using a styled dataframe if Jinja2 is installed +df = topic_model.visualize_approximate_distribution(docs[0], topic_token_distr[0]); df +``` + +

Supervised Topic Modeling

+ +BERTopic now supports fully-supervised classification! Instead of using a clustering algorithm, like HDBSCAN, we can replace it with a classifier, like Logistic Regression: + +```python +from bertopic import BERTopic +from bertopic.dimensionality import BaseDimensionalityReduction +from sklearn.datasets import fetch_20newsgroups +from sklearn.linear_model import LogisticRegression + +# Get labeled data +data= fetch_20newsgroups(subset='all', remove=('headers', 'footers', 'quotes')) +docs = data['data'] +y = data['target'] + +# Allows us to skip over the dimensionality reduction step +empty_dimensionality_model = BaseDimensionalityReduction() + +# Create a classifier to be used instead of the cluster model +clf= LogisticRegression() + +# Create a fully supervised BERTopic instance +topic_model= BERTopic( + umap_model=empty_dimensionality_model, + hdbscan_model=clf +) +topics, probs = topic_model.fit_transform(docs, y=y) +``` + +

Manual Topic Modeling

+ +When you already have a bunch of labels and simply want to extract topic representations from them, you might not need to actually learn how those can predicted. We can bypass the `embeddings -> dimensionality reduction -> clustering` steps and go straight to the c-TF-IDF representation of our labels: + +```python +from bertopic import BERTopic +from bertopic.backend import BaseEmbedder +from bertopic.cluster import BaseCluster +from bertopic.dimensionality import BaseDimensionalityReduction + +# Prepare our empty sub-models and reduce frequent words while we are at it. +empty_embedding_model = BaseEmbedder() +empty_dimensionality_model = BaseDimensionalityReduction() +empty_cluster_model = BaseCluster() + +# Fit BERTopic without actually performing any clustering +topic_model= BERTopic( + embedding_model=empty_embedding_model, + umap_model=empty_dimensionality_model, + hdbscan_model=empty_cluster_model, +) +topics, probs = topic_model.fit_transform(docs, y=y) +``` + +

Outlier Reduction

+ +Outlier reduction is an frequently-discussed topic in BERTopic as its default cluster model, HDBSCAN, has a tendency to generate many outliers. This often helps in the topic representation steps, as we do not consider documents that are less relevant, but you might want to still assign those outliers to actual topics. In the modular philosophy of BERTopic, keeping training times in mind, it is now possible to perform outlier reduction **after** having trained your topic model. This allows for ease of iteration and prevents having to train BERTopic many times to find the parameters you are searching for. There are 4 different strategies that you can use, so make sure to check out the [documentation](https://maartengr.github.io/BERTopic/getting_started/outlier_reduction/outlier_reduction.html)! + +Using it is rather straightforward: + +```python +new_topics = topic_model.reduce_outliers(docs, topics) +``` + +

Lightweight BERTopic

+ +The default embedding model in BERTopic is one of the amazing sentence-transformers models, namely `"all-MiniLM-L6-v2"`. Although this model performs well out of the box, it typically needs a GPU to transform the documents into embeddings in a reasonable time. Moreover, the installation requires `pytorch` which often results in a rather large environment, memory-wise. + +Fortunately, it is possible to install BERTopic without `sentence-transformers` and use it as a lightweight solution instead. The installation can be done as follows: + +```bash +pip install --no-deps bertopic +pip install --upgrade numpy hdbscan umap-learn pandas scikit-learn tqdm plotly pyyaml +``` + +Then, we can use BERTopic without `sentence-transformers` as follows using a CPU-based embedding technique: + +```python +from sklearn.pipeline import make_pipeline +from sklearn.decomposition import TruncatedSVD +from sklearn.feature_extraction.text import TfidfVectorizer + +pipe = make_pipeline( + TfidfVectorizer(), + TruncatedSVD(100) +) + +topic_model = BERTopic(embedding_model=pipe) +``` + +As a result, the entire package and resulting model can be run quickly on the CPU and no GPU is necessary! + +

Document Information

+ +Get information about the documents on which the topic was trained including the documents themselves, their respective topics, the name of each topic, the top n words of each topic, whether it is a representative document, and the probability of the clustering if the cluster model supports it. There are also options to include other metadata, such as the topic distributions or the x and y coordinates of the reduced embeddings that you can learn more about here. + +To get the document info, you will only need to pass the documents on which the topic model was trained: + + +```python +>>> topic_model.get_document_info(docs) + +Document Topic Name Top_n_words Probability ... +I am sure some bashers of Pens... 0 0_game_team_games_season game - team - games... 0.200010 ... +My brother is in the market for... -1 -1_can_your_will_any can - your - will... 0.420668 ... +Finally you said what you dream... -1 -1_can_your_will_any can - your - will... 0.807259 ... +Think!

+ +* Fix loading pre-trained BERTopic model +* Fix mapping of probabilities +* Fix [#190](https://github.com/MaartenGr/BERTopic/issues/190) + + +**Guided BERTopic**: + +Guided BERTopic works in two ways: + +First, we create embeddings for each seeded topics by joining them and passing them through the document embedder. +These embeddings will be compared with the existing document embeddings through cosine similarity and assigned a label. +If the document is most similar to a seeded topic, then it will get that topic's label. +If it is most similar to the average document embedding, it will get the -1 label. +These labels are then passed through UMAP to create a semi-supervised approach that should nudge the topic creation to the seeded topics. + +Second, we take all words in `seed_topic_list` and assign them a multiplier larger than 1. +Those multipliers will be used to increase the IDF values of the words across all topics thereby increasing +the likelihood that a seeded topic word will appear in a topic. This does, however, also increase the chance of an +irrelevant topic having unrelated words. In practice, this should not be an issue since the IDF value is likely to +remain low regardless of the multiplier. The multiplier is now a fixed value but may change to something more elegant, +like taking the distribution of IDF values and its position into account when defining the multiplier. + +```python +seed_topic_list = [["company", "billion", "quarter", "shrs", "earnings"], + ["acquisition", "procurement", "merge"], + ["exchange", "currency", "trading", "rate", "euro"], + ["grain", "wheat", "corn"], + ["coffee", "cocoa"], + ["natural", "gas", "oil", "fuel", "products", "petrol"]] + +topic_model = BERTopic(seed_topic_list=seed_topic_list) +topics, probs = topic_model.fit_transform(docs) +``` + + +## **Version 0.8.1** +*Release date: 8 June, 2021* + +**Highlights**: + +* Improved models: + * For English documents the default is now: `"paraphrase-MiniLM-L6-v2"` + * For Non-English or multi-lingual documents the default is now: `"paraphrase-multilingual-MiniLM-L12-v2"` + * Both models show not only great performance but are much faster! +* Add interactive visualizations to the `plotting` API documentation + +For better performance, please use the following models: + +* English: `"paraphrase-mpnet-base-v2"` +* Non-English or multi-lingual: `"paraphrase-multilingual-mpnet-base-v2"` + +**Fixes**: + +* Improved unit testing for more stability +* Set transformers version for Flair + +## **Version 0.8.0** +*Release date: 31 May, 2021* + +**Highlights**: + +* Additional visualizations: + * Topic Hierarchy: `topic_model.visualize_hierarchy()` + * Topic Similarity Heatmap: `topic_model.visualize_heatmap()` + * Topic Representation Barchart: `topic_model.visualize_barchart()` + * Term Score Decline: `topic_model.visualize_term_rank()` +* Created `bertopic.plotting` library to easily extend visualizations +* Improved automatic topic reduction by using HDBSCAN to detect similar topics +* Sort topic ids by their frequency. -1 is the outlier class and contains typically the most documents.

Using custom embeddings allows you to try out BERTopic several times until you find the topics that suit you best. You only need to generate the embeddings themselves once and run BERTopic several times +with different parameters. + +If you want to reproduce the results, at the expense of [performance](https://umap-learn.readthedocs.io/en/latest/reproducibility.html), you can set a `random_state` in UMAP to prevent +any stochastic behavior: + +```python +from bertopic import BERTopic +from umap import UMAP + +umap_model = UMAP(n_neighbors=15, n_components=5, + min_dist=0.0, metric='cosine', random_state=42) +topic_model = BERTopic(umap_model=umap_model) +``` + +## **Which embedding model should I choose?** +Unfortunately, there is not a definitive list of the best models for each language, this highly depends on your data, the model, and your specific use case. However, the default model in BERTopic (`"all-MiniLM-L6-v2"`) works great for **English** documents. In contrast, for **multi-lingual** documents or any other language, `"paraphrase-multilingual-MiniLM-L12-v2"` has shown great performance. + +If you want to use a model that provides a higher quality, but takes more computing time, then I would advise using `all-mpnet-base-v2` and `paraphrase-multilingual-mpnet-base-v2` instead. + +**MTEB Leaderboard** +New embedding models are released frequently and their performance keeps getting better. To keep track of the best embedding models out there, you can visit the [MTEB leaderboard](https://huggingface.co/spaces/mteb/leaderboard). It is an excellent place for selecting the embedding that works best for you. For example, if you want the best of the best, then the top 5 models might the place to look. + +Many of these models can be used with `SentenceTransformers` in BERTopic, like so: + +```python +from bertopic import BERTopic +from sentence_transformers import SentenceTransformer + +embedding_model = SentenceTransformer("BAAI/bge-base-en-v1.5") +topic_model = BERTopic(embedding_model=embedding_model) +``` + +**SentenceTransformers** +[SentenceTransformers](https://www.sbert.net/docs/pretrained_models.html#sentence-embedding-models) work typically quite well +and are the preferred models to use. They are great at generating document embeddings and have several +multi-lingual versions available. + +**πŸ€— transformers** +BERTopic allows you to use any πŸ€— transformers model. These models are typically embeddings created on a word/sentence level but can easily be pooled using Flair (see Guides/Embeddings). If you have a specific language for which you want to generate embeddings, you can choose the model [here](https://huggingface.co/models). + +## **How do I reduce topic outliers?** +There are several ways we can reduce outliers. + +First, the amount of datapoint classified as outliers is handled by the `min_samples` parameters in HDBSCAN. This value is automatically set to the +same value of `min_cluster_size`. However, you can set it independently if you want to reduce the number of generated outliers. Lowering this value will +result in less noise being generated. + +```python +from bertopic import BERTopic +from hdbscan import HDBSCAN + +hdbscan_model = HDBSCAN(min_cluster_size=10, metric='euclidean', + cluster_selection_method='eom', prediction_data=True, min_samples=5) +topic_model = BERTopic(hdbscan_model=hdbscan_model) +topics, probs = topic_model.fit_transform(docs) +``` + +!!! note "Note" + Although this will lower outliers found in the data, this might force outliers to be put into topics where they do not belong. So make + sure to strike a balance between keeping noise and reducing outliers. + +Second, after training our BERTopic model, we can assign outliers to topics by making use of the `.reduce_outliers` function in BERTopic. An advantage of using this approach is that there are four built in strategies one can choose for reducing outliers. Moreover, this technique allows the user to experiment with reducing outliers across a number of strategies and parameters without actually having to re-train the topic model each time. You can learn more about the `.reduce_outlier` function [here](https://maartengr.github.io/BERTopic/getting_started/outlier_reduction/outlier_reduction.html). The following is a minimal example of how to use this function: + +```python +from bertopic import BERTopic + +# Train your BERTopic model +topic_model = BERTopic() +topics, probs = topic_model.fit_transform(docs) + +# Reduce outliers +new_topics = topic_model.reduce_outliers(docs, topics) +``` + +Third, we can replace HDBSCAN with any other clustering algorithm that we want. So we can choose a clustering algorithm, like k-Means, that +does not produce any outliers at all. Using k-Means instead of HDBSCAN is straightforward: + +```python +from bertopic import BERTopic +from sklearn.cluster import KMeans + +cluster_model = KMeans(n_clusters=50) +topic_model = BERTopic(hdbscan_model=cluster_model) +``` + + +## **How do I remove stop words?** +At times, stop words might end up in our topic representations. This is something we typically want to avoid as they contribute little to the interpretation of the topics. However, removing stop words as a preprocessing step is not advised as the transformer-based embedding models that we use need the full context to create accurate embeddings. + +Instead, we can use the `CountVectorizer` to preprocess our documents **after** having generated embeddings and clustered +our documents. I have found almost no disadvantages to using the `CountVectorizer` to remove stop words and +it is something I would strongly advise to try out: + +```python +from bertopic import BERTopic +from sklearn.feature_extraction.text import CountVectorizer + +vectorizer_model = CountVectorizer(stop_words="english") +topic_model = BERTopic(vectorizer_model=vectorizer_model) +``` + +We can also use the `ClassTfidfTransformer` to reduce the impact of frequent words. The result is very similar to explicitly removing stop words but this process does this automatically: + +```python +from bertopic import BERTopic +from bertopic.vectorizers import ClassTfidfTransformer + +ctfidf_model = ClassTfidfTransformer(reduce_frequent_words=True) +topic_model = BERTopic(ctfidf_model=ctfidf_model) +``` + +## **How can I speed up BERTopic?** +You can speed up BERTopic by either generating your embeddings beforehand or by +setting `calculate_probabilities` to False. Calculating the probabilities is quite expensive and can significantly increase the computation time. Thus, only use it if you do not mind waiting a bit before the model is done running or if you have less than a couple of hundred thousand documents. + +Also, make sure to use a GPU when extracting the sentence/document embeddings. Transformer models typically require a GPU and using only a CPU can slow down computation time quite a lot. However, if you do not have access to a GPU, looking into quantization might help. + +Lastly, it is also possible to speed up BERTopic with [cuML's](https://rapids.ai/start.html#rapids-release-selector) GPU acceleration of UMAP and HDBSCAN: + + +```python +from bertopic import BERTopic +from cuml.cluster import HDBSCAN +from cuml.manifold import UMAP + +# Create instances of GPU-accelerated UMAP and HDBSCAN +umap_model = UMAP(n_components=5, n_neighbors=15, min_dist=0.0) +hdbscan_model = HDBSCAN(min_samples=10, gen_min_span_tree=True, prediction_data=True) + +# Pass the above models to be used in BERTopic +topic_model = BERTopic(umap_model=umap_model, hdbscan_model=hdbscan_model) +``` + + +## **I am facing memory issues. Help!** +There are several ways to perform computation with large datasets: + +* First, you can set `low_memory` to True when instantiating BERTopic. +This may prevent blowing up the memory in UMAP. + +* Second, setting `calculate_probabilities` to False when instantiating BERTopic prevents a huge document-topic +probability matrix from being created. Moreover, HDBSCAN is quite slow when it tries to calculate probabilities on large datasets. + +* Third, you can set the minimum frequency of words in the CountVectorizer class to reduce the size of the resulting +sparse c-TF-IDF matrix. You can do this as follows: + +```python +from bertopic import BERTopic +from sklearn.feature_extraction.text import CountVectorizer + +vectorizer_model = CountVectorizer(ngram_range=(1, 2), stop_words="english", min_df=10) +topic_model = BERTopic(vectorizer_model=vectorizer_model) +``` + +The [min_df](https://scikit-learn.org/stable/modules/generated/sklearn.feature_extraction.text.CountVectorizer.html) +parameter is used to indicate the minimum frequency of words. Setting this value larger than 1 can significantly reduce memory. + +* Fourth, you can use online topic modeling instead to use BERTopic on big data by training the model in chunks + +If the problem persists, then this could be an issue related to your available memory. The processing of millions of documents is quite computationally expensive and sufficient RAM is necessary. + +## **I have only a few topics, how do I increase them?** +There are several reasons why your topic model may result in only a few topics: + +* First, you might only have a few documents (~1000). This makes it very difficult to properly +extract topics due to the little amount of data available. Increasing the number of documents +might solve your issues. + +* Second, `min_topic_size` might be simply too large for your number of documents. If you decrease +the minimum size of topics, then you are much more likely to increase the number of topics generated. +You could also decrease the `n_neighbors` parameter used in `UMAP` if this does not work. + +* Third, although this does not happen very often, there simply aren't that many topics to be found +in your documents. You can often see this when you have many `-1` topics, which is not a topic +but a category of outliers. + +## **I have too many topics, how do I decrease them?** +If you have a large dataset, then it is possible to generate thousands of topics. Especially with large datasets, there is a good chance they contain many small topics. In practice, you might want a few hundred topics at most to interpret them nicely. + +There are a few ways of decreasing the number of generated topics: + +* First, we can set the `min_topic_size` in the BERTopic initialization much higher (e.g., 300) to make sure that those small clusters will not be generated. This is an HDBSCAN parameter that specifies the minimum number of documents needed in a cluster. More documents in a cluster mean fewer topics will be generated. + +* Second, you can create a custom UMAP model and set `n_neighbors` much higher than the default 15 (e.g., 200). This also prevents those micro clusters to be generated as it will need many neighboring documents to create a cluster. + +* Third, we can set `nr_topics` to a value that seems logical to the user. Do note that topics are forced +to merge which might result in a lower quality of topics. In practice, I would advise using +`nr_topic="auto"` as that will merge topics that are very similar. Dissimilar topics will +therefore remain separated. + +## **How do I calculate the probabilities of all topics in a document?** +Although it is possible to calculate all the probabilities, the process of doing so is quite computationally +inefficient and might significantly increase the computation time. To prevent this, the probabilities are +not calculated as a default. To calculate them, you will have to set `calculate_probabilities` to True: + +```python +from bertopic import BERTopic +topic_model = BERTopic(calculate_probabilities=True) +topics, probs = topic_model.fit_transform(docs) +``` + +!!! note + The `calculate_probabilties` parameter is only used when using HDBSCAN or cuML's HDBSCAN model. In other words, this will not work when using a model other than HDBSCAN. Instead, we can approximate the topic distributions across all documents with [`.approximate_distribution`](https://maartengr.github.io/BERTopic/getting_started/distribution/distribution.html). + +## **Numpy gives me an error when running BERTopic** +With the release of Numpy 1.20.0, there have been significant issues with using that version (and previous ones) due to compilation issues and pypi. + +This is a known issue with the order of installation using pypi. You can find more details about this issue +[here](https://github.com/lmcinnes/umap/issues/567) and [here](https://github.com/scikit-learn-contrib/hdbscan/issues/457). + +I would suggest doing one of the following: + +* Install the newest version from BERTopic (>= v0.5). +* You can install hdbscan with `pip install hdbscan --no-cache-dir --no-binary :all: --no-build-isolation` which might resolve the issue +* Install BERTopic in a fresh environment using these steps. + +## **How can I run BERTopic without an internet connection?** +The great thing about using sentence-transformers is that it searches automatically for an embedding model locally. +If it cannot find one, it will download the pre-trained model from its servers. +Make sure that you set the correct path for sentence-transformers to work. You can find a bit more about that +[here](https://github.com/UKPLab/sentence-transformers/issues/888). + +You can download the corresponding model [here](https://public.ukp.informatik.tu-darmstadt.de/reimers/sentence-transformers/v0.2/) +and unzip it. Then, simply use the following to create your embedding model: + +```python +from sentence_transformers import SentenceTransformer +embedding_model = SentenceTransformer('path/to/unzipped/model') +``` + +Then, pass it to BERTopic: + +```python +from bertopic import BERTopic +topic_model = BERTopic(embedding_model=embedding_model) +``` + +## **Can I use the GPU to speed up the model?** +Yes. The GPU is automatically used when you use a SentenceTransformer or Flair embedding model. Using +a CPU would then definitely slow things down. However, you can use other embeddings like TF-IDF or Doc2Vec +embeddings in BERTopic which do not depend on GPU acceleration. + +You can use [cuML](https://rapids.ai/start.html#rapids-release-selector) to speed up both +UMAP and HDBSCAN through GPU acceleration: + +```python +from bertopic import BERTopic +from cuml.cluster import HDBSCAN +from cuml.manifold import UMAP + +# Create instances of GPU-accelerated UMAP and HDBSCAN +umap_model = UMAP(n_components=5, n_neighbors=15, min_dist=0.0) +hdbscan_model = HDBSCAN(min_samples=10, gen_min_span_tree=True, prediction_data=True) + +# Pass the above models to be used in BERTopic +topic_model = BERTopic(umap_model=umap_model, hdbscan_model=hdbscan_model) +topics, probs = topic_model.fit_transform(docs) +``` + +Depending on the embeddings you are using, you might want to normalize them first to force a cosine-related distance metric in UMAP: + +```python +from cuml.preprocessing import normalize +embeddings = normalize(embeddings) +``` + +## **How can I use BERTopic with Chinese documents?** +Currently, CountVectorizer tokenizes text by splitting whitespace which does not work for Chinese. +To get it to work, you will have to create a custom `CountVectorizer` with `jieba`: + +```python +from sklearn.feature_extraction.text import CountVectorizer +import jieba + +def tokenize_zh(text): + words = jieba.lcut(text) + return words + +vectorizer = CountVectorizer(tokenizer=tokenize_zh) +``` + +Next, we pass our custom vectorizer to BERTopic and create our topic model: + +```python +from bertopic import BERTopic +topic_model = BERTopic(embedding_model=model, verbose=True, vectorizer_model=vectorizer) +topics, _ = topic_model.fit_transform(docs, embeddings=embeddings) +``` + +## **Why does it take so long to import BERTopic?** +The main culprit here seems to be UMAP. After running tests with [Tuna](https://github.com/nschloe/tuna) we +can see that most of the resources when importing BERTopic can be dedicated to UMAP: + + + +Unfortunately, there currently is no fix for this issue. The most recent ticket regarding this +issue can be found [here](https://github.com/lmcinnes/umap/issues/631). + +## **Should I preprocess the data?** +No. By using document embeddings there is typically no need to preprocess the data as all parts of a document +are important in understanding the general topic of the document. Although this holds in 99% of cases, if you +have data that contains a lot of noise, for example, HTML-tags, then it would be best to remove them. HTML-tags +typically do not contribute to the meaning of a document and should therefore be removed. However, if you apply +topic modeling to HTML-code to extract topics of code, then it becomes important. diff --git a/BERTopic/docs/getting_started/best_practices/best_practices.md b/BERTopic/docs/getting_started/best_practices/best_practices.md new file mode 100644 index 0000000000000000000000000000000000000000..dd963a7d65004a374fa721d592ac5d698f727526 --- /dev/null +++ b/BERTopic/docs/getting_started/best_practices/best_practices.md @@ -0,0 +1,407 @@ +[![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/drive/1BoQ_vakEVtojsd2x_U6-_x52OOuqruj2?usp=sharing) - Overview of Best Practices + +Through the nature of BERTopic, its modularity, many variations of the topic modeling technique is possible. However, during the development and through the usage of the package, a set of best practices have been developed that generally lead to great results. + +The following are a number of steps, parameters, and settings that you can use that will generally improve the quality of the resulting topics. In other words, after going through the quick start and getting a feeling for the API these steps should get you to the next level of performance. + +!!! Note + Although these are called *best practices*, it does not necessarily mean that they work across all use cases perfectly. The underlying modular nature of BERTopic is meant to take different use cases into account. After going through these practices it is advised to fine-tune wherever necessary. + + +To showcase how these "best practices" work, we will go through an example dataset and apply all practices to it. + +## **Data** + +For this example, we will use a dataset containing abstracts and metadata from [ArXiv articles](https://huggingface.co/datasets/arxiv_dataset). + + +```python +from datasets import load_dataset + +dataset = load_dataset("CShorten/ML-ArXiv-Papers")["train"] + +# Extract abstracts to train on and corresponding titles +abstracts = dataset["abstract"] +titles = dataset["title"] +``` + +!!! Tip "Sentence Splitter" + + Whenever you have large documents, you typically want to split them up into either paragraphs or sentences. A nice way to do so is by using NLTK's sentence splitter which is nothing more than: + + ```python + from nltk.tokenize import sent_tokenize, word_tokenize + sentences = [sent_tokenize(abstract) for abstract in abstracts] + sentences = [sentence for doc in sentences for sentence in doc] + ``` + +## **Pre-calculate Embeddings** +After having created our data, namely `abstracts`, we can dive into the very first best practice, **pre-calculating embeddings**. + +BERTopic works by converting documents into numerical values, called embeddings. This process can be very costly, especially if we want to iterate over parameters. Instead, we can calculate those embeddings once and feed them to BERTopic to skip calculating embeddings each time. + +```python +from sentence_transformers import SentenceTransformer + +# Pre-calculate embeddings +embedding_model = SentenceTransformer("all-MiniLM-L6-v2") +embeddings = embedding_model.encode(abstracts, show_progress_bar=True) +``` + +!!! Tip + New embedding models are released frequently and their performance keeps getting better. To keep track of the best embedding models out there, you can visit the [MTEB leaderboard](https://huggingface.co/spaces/mteb/leaderboard). It is an excellent place for selecting the embedding that works best for you. For example, if you want the best of the best, then the top 5 models might the place to look. + + +## **Preventing Stochastic Behavior** +In BERTopic, we generally use a dimensionality reduction algorithm to reduce the size of the embeddings. This is done to prevent the [curse of dimensionality](https://en.wikipedia.org/wiki/Curse_of_dimensionality) to a certain degree. + +As a default, this is done with [UMAP](https://github.com/lmcinnes/umap) which is an incredible algorithm for reducing dimensional space. However, by default, it shows stochastic behavior which creates different results each time you run it. To prevent that, we will need to set a `random_state` of the model before passing it to BERTopic. + +As a result, we can now fully reproduce the results each time we run the model. + +```python +from umap import UMAP + +umap_model = UMAP(n_neighbors=15, n_components=5, min_dist=0.0, metric='cosine', random_state=42) +``` + +## **Controlling Number of Topics** +There is a parameter to control the number of topics, namely `nr_topics`. This parameter, however, merges topics **after** they have been created. It is a parameter that supports creating a fixed number of topics. + +However, it is advised to control the number of topics through the cluster model which is by default HDBSCAN. HDBSCAN has a parameter, namely `min_cluster_size` that indirectly controls the number of topics that will be created. + +A higher `min_cluster_size` will generate fewer topics and a lower `min_cluster_size` will generate more topics. + +Here, we will go with `min_cluster_size=150` to prevent too many micro-clusters from being created: + +```python +from hdbscan import HDBSCAN + +hdbscan_model = HDBSCAN(min_cluster_size=150, metric='euclidean', cluster_selection_method='eom', prediction_data=True) +``` + +## **Improving Default Representation** +The default representation of topics is calculated through [c-TF-IDF](https://maartengr.github.io/BERTopic/algorithm/algorithm.html#5-topic-representation). However, c-TF-IDF is powered by the [CountVectorizer](https://maartengr.github.io/BERTopic/getting_started/vectorizers/vectorizers.html) which converts text into tokens. Using the CountVectorizer, we can do a number of things: + +* Remove stopwords +* Ignore infrequent words +* Increase the n-gram range + +In other words, we can preprocess the topic representations **after** documents are assigned to topics. This will not influence the clustering process in any way. + +Here, we will ignore English stopwords and infrequent words. Moreover, by increasing the n-gram range we will consider topic representations that are made up of one or two words. + +```python +from sklearn.feature_extraction.text import CountVectorizer +vectorizer_model = CountVectorizer(stop_words="english", min_df=2, ngram_range=(1, 2)) +``` + +## **Additional Representations** +Previously, we have tuned the default representation but there are quite a number of [other topic representations](https://maartengr.github.io/BERTopic/getting_started/representation/representation.html) in BERTopic that we can choose from. From [KeyBERTInspired](https://maartengr.github.io/BERTopic/getting_started/representation/representation.html#keybertinspired) and [PartOfSpeech](https://maartengr.github.io/BERTopic/getting_started/representation/representation.html#partofspeech), to [OpenAI's ChatGPT](https://maartengr.github.io/BERTopic/getting_started/representation/llm.html#chatgpt) and [open-source](https://maartengr.github.io/BERTopic/getting_started/representation/llm.html#langchain) alternatives, many representations are possible. + +In BERTopic, you can model many different topic representations simultaneously to test them out and get different perspectives of topic descriptions. This is called [multi-aspect](https://maartengr.github.io/BERTopic/getting_started/multiaspect/multiaspect.html) topic modeling. + +Here, we will demonstrate a number of interesting and useful representations in BERTopic: + +* KeyBERTInspired + * A method that derives inspiration from how KeyBERT works +* PartOfSpeech + * Using SpaCy's POS tagging to extract words +* MaximalMarginalRelevance + * Diversify the topic words +* OpenAI + * Use ChatGPT to label our topics + + +```python +import openai +from bertopic.representation import KeyBERTInspired, MaximalMarginalRelevance, OpenAI, PartOfSpeech + +# KeyBERT +keybert_model = KeyBERTInspired() + +# Part-of-Speech +pos_model = PartOfSpeech("en_core_web_sm") + +# MMR +mmr_model = MaximalMarginalRelevance(diversity=0.3) + +# GPT-3.5 +client = openai.OpenAI(api_key="sk-...") +prompt = """ +I have a topic that contains the following documents: +[DOCUMENTS] +The topic is described by the following keywords: [KEYWORDS] + +Based on the information above, extract a short but highly descriptive topic label of at most 5 words.

Here, several different representations, keywords and labels for our topics will be created. If you want to iterate over the topic model it is advised to use the pre-calculated embeddings as that significantly speeds up training. + +```python +from bertopic import BERTopic + +topic_model = BERTopic( + + # Pipeline models + embedding_model=embedding_model, + umap_model=umap_model, + hdbscan_model=hdbscan_model, + vectorizer_model=vectorizer_model, + representation_model=representation_model, + + # Hyperparameters + top_n_words=10, + verbose=True +) + +# Train model +topics, probs = topic_model.fit_transform(abstracts, embeddings) + +# Show topics +topic_model.get_topic_info() +``` + +To get all representations for a single topic, we simply run the following: + +```python +>>> topic_model.get_topic(1, full=True) +{'Main': [('adversarial', 0.028838938990764302), + ('attacks', 0.021726302042463556), + ('attack', 0.016803574415028524), + ('robustness', 0.013046135743326167), + ('adversarial examples', 0.01151254557995679), + ('examples', 0.009920962487998853), + ('perturbations', 0.009053305826870773), + ('adversarial attacks', 0.008747627064844006), + ('malware', 0.007675131707700338), + ('defense', 0.007365955840313783)], + 'KeyBERT': [('adversarial training', 0.76427937), + ('adversarial attack', 0.74271905), + ('vulnerable adversarial', 0.73302543), + ('adversarial', 0.7311052), + ('adversarial examples', 0.7179245), + ('adversarial attacks', 0.7082), + ('adversarially', 0.7005141), + ('adversarial robustness', 0.69911957), + ('adversarial perturbations', 0.6588783), + ('adversary', 0.4467769)], + 'OpenAI': [('Adversarial attacks and defense', 1)], + 'MMR': [('adversarial', 0.028838938990764302), + ('attacks', 0.021726302042463556), + ('attack', 0.016803574415028524), + ('robustness', 0.013046135743326167), + ('adversarial examples', 0.01151254557995679), + ('examples', 0.009920962487998853), + ('perturbations', 0.009053305826870773), + ('adversarial attacks', 0.008747627064844006), + ('malware', 0.007675131707700338), + ('defense', 0.007365955840313783)], + 'POS': [('adversarial', 0.028838938990764302), + ('attacks', 0.021726302042463556), + ('attack', 0.016803574415028524), + ('robustness', 0.013046135743326167), + ('adversarial examples', 0.01151254557995679), + ('examples', 0.009920962487998853), + ('perturbations', 0.009053305826870773), + ('adversarial attacks', 0.008747627064844006), + ('malware', 0.007675131707700338), + ('defense', 0.007365955840313783)]} +``` + +**NOTE**: The labels generated by OpenAI's **ChatGPT** are especially interesting to use throughout your model. Below, we will go into more detail how to set that as a custom label. + +!!! Tip "Parameters" + If you would like to return the topic-document probability matrix, then it is advised to use `calculate_probabilities=True`. Do note that this can significantly slow down training. To speed it up, use [cuML's HDBSCAN](https://maartengr.github.io/BERTopic/getting_started/clustering/clustering.html#cuml-hdbscan) instead. You could also approximate the topic-document probability matrix with `.approximate_distribution` which will be discussed later. + + +## **(Custom) Labels** +The default label of each topic are the top 3 words in each topic combined with an underscore between them. + +This, of course, might not be the best label that you can think of for a certain topic. Instead, we can use `.set_topic_labels` to manually label all or certain topics. + +We can also use `.set_topic_labels` to use one of the other topic representations that we had before, like `KeyBERTInspired` or even `OpenAI`. + +```python +# Label the topics yourself +topic_model.set_topic_labels({1: "Space Travel", 7: "Religion"}) + +# or use one of the other topic representations, like KeyBERTInspired +keybert_topic_labels = {topic: " | ".join(list(zip(*values))[0][:3]) for topic, values in topic_model.topic_aspects_["KeyBERT"].items()} +topic_model.set_topic_labels(keybert_topic_labels) + +# or ChatGPT's labels +chatgpt_topic_labels = {topic: " | ".join(list(zip(*values))[0]) for topic, values in topic_model.topic_aspects_["OpenAI"].items()} +chatgpt_topic_labels[-1] = "Outlier Topic" +topic_model.set_topic_labels(chatgpt_topic_labels) +``` + +Now that we have set the updated topic labels, we can access them with the many functions used throughout BERTopic. Most notably, you can show the updated labels in visualizations with the `custom_labels=True` parameters. + +If we were to run `topic_model.get_topic_info()` it will now include the column `CustomName`. That is the custom label that we just created for each topic. + +## **Topic-Document Distribution** +If using `calculate_probabilities=True` is not possible, then you can [approximate the topic-document distributions](https://maartengr.github.io/BERTopic/getting_started/distribution/distribution.html) using `.approximate_distribution`. It is a fast and flexible method for creating different topic-document distributions. + +```python +# `topic_distr` contains the distribution of topics in each document +topic_distr, _ = topic_model.approximate_distribution(abstracts, window=8, stride=4) +``` + +Next, lets take a look at a specific abstract and see how the topic distribution was extracted: + +```python +# Visualize the topic-document distribution for a single document +topic_model.visualize_distribution(topic_distr[abstract_id], custom_labels=True) +``` + +It seems to have extracted a number of topics that are relevant and shows the distributions of these topics across the abstract. We can go one step further and visualize them on a token-level: + +```python +# Calculate the topic distributions on a token-level +topic_distr, topic_token_distr = topic_model.approximate_distribution(abstracts[abstract_id], calculate_tokens=True) + +# Visualize the token-level distributions +df = topic_model.visualize_approximate_distribution(abstracts[abstract_id], topic_token_distr[0]) +df +``` + +!!! Tip "use_embedding_model" + As a default, we compare the c-TF-IDF calculations between the token sets and all topics. Due to its bag-of-word representation, this is quite fast. However, you might want to use the selected embedding_model instead to do this comparison. Do note that due to the many token sets, it is often computationally quite a bit slower: + + ```python + topic_distr, _ = topic_model.approximate_distribution(docs, use_embedding_model=True) + ``` +## **Outlier Reduction** +By default, HDBSCAN generates outliers which is a helpful mechanic in creating accurate topic representations. However, you might want to assign every single document to a topic. We can use `.reduce_outliers` to map some or all outliers to a topic: + +```python +# Reduce outliers +new_topics = topic_model.reduce_outliers(abstracts, topics) + +# Reduce outliers with pre-calculate embeddings instead +new_topics = topic_model.reduce_outliers(abstracts, topics, strategy="embeddings", embeddings=embeddings) +``` + +!!! Note "Update Topics with Outlier Reduction" + After having generated updated topic assignments, we can pass them to BERTopic in order to update the topic representations: + + ```python + topic_model.update_topics(docs, topics=new_topics) + ``` + + It is important to realize that updating the topics this way may lead to errors if topic reduction or topic merging techniques are used afterwards. The reason for this is that when you assign a -1 document to topic 1 and another -1 document to topic 2, it is unclear how you map the -1 documents. Is it matched to topic 1 or 2. + + +## **Visualize Topics** + +With visualizations, we are closing into the realm of subjective "best practices". These are things that I generally do because I like the representations but your experience might differ. + +Having said that, there are two visualizations that are my go-to when visualizing the topics themselves: + +* `topic_model.visualize_topics()` +* `topic_model.visualize_hierarchy()` + +```python +# Visualize topics with custom labels +topic_model.visualize_topics(custom_labels=True) + +# Visualize hierarchy with custom labels +topic_model.visualize_hierarchy(custom_labels=True) +``` + +## **Visualize Documents** + +When visualizing documents, it helps to have embedded the documents beforehand to speed up computation. Fortunately, we have already done that as a "best practice". + +Visualizing documents in 2-dimensional space helps in understanding the underlying structure of the documents and topics. + +```python +# Reduce dimensionality of embeddings, this step is optional but much faster to perform iteratively: +reduced_embeddings = UMAP(n_neighbors=10, n_components=2, min_dist=0.0, metric='cosine').fit_transform(embeddings) +``` + +The following plot is **interactive** which means that you can zoom in, double click on a label to only see that one and generally interact with the plot: + +```python +# Visualize the documents in 2-dimensional space and show the titles on hover instead of the abstracts +# NOTE: You can hide the hover with `hide_document_hover=True` which is especially helpful if you have a large dataset +# NOTE: You can also hide the annotations with `hide_annotations=True` which is helpful to see the larger structure +topic_model.visualize_documents(titles, reduced_embeddings=reduced_embeddings, custom_labels=True) +``` + +!!! Note "2-dimensional space" + Although visualizing the documents in 2-dimensional gives an idea of their underlying structure, there is a risk involved. + + Visualizing the documents in 2-dimensional space means that we have lost significant information since the original embeddings were more than 384 dimensions. Condensing all that information in 2 dimensions is simply not possible. In other words, it is merely an **approximation**, albeit quite an accurate one. + +## **Serialization** + +When saving a BERTopic model, there are several ways in doing so. You can either save the entire model with `pickle`, `pytorch`, or `safetensors`. + +Personally, I would advise going with `safetensors` whenever possible. The reason for this is that the format allows for a very small topic model to be saved and shared. + +When saving a model with `safetensors`, it skips over saving the dimensionality reduction and clustering models.

+
+ +To perform this approximation, each document is split into tokens according to the provided tokenizer in the `CountVectorizer`.

These are called token sets. +For each of these token sets, we calculate their c-TF-IDF representation and find out how similar they are to the previously generated topics. +Then, the similarities to the topics for each token set are summed to create a topic distribution for the entire document. + +Although it is often said that documents can contain a mixture of topics, these are often modeled by assigning each word to a single topic. +With this approach, we take into account that there may be multiple topics for a single word. + +We can make this multiple-topic word assignment a bit more accurate by then splitting these token sets up into individual tokens and assigning +the topic distributions for each token set to each individual token. That way, we can visualize the extent to which a certain word contributes +to a document's topic distribution. + +## **Example** + +To calculate our topic distributions, we first need to fit a basic topic model: + +```python +from bertopic import BERTopic +from sklearn.datasets import fetch_20newsgroups + +docs = fetch_20newsgroups(subset='all', remove=('headers', 'footers', 'quotes'))['data'] +topic_model = BERTopic().fit(docs) +``` + +After doing so, we can approximate the topic distributions for your documents: + +```python +topic_distr, _ = topic_model.approximate_distribution(docs) +``` + +The resulting `topic_distr` is a *n* x *m* matrix where *n* are the topics and *m* the documents.

You can install Jinja via `pip install jinja2` + +## **Parameters** +There are a few parameters that are of interest which will be discussed below. + + +### **batch_size** +Creating token sets for each document can result in quite a large list of token sets. The similarity of these token sets with the topics can result a large matrix that might not fit into memory anymore. To circumvent this, we can process batches of documents instead to minimize the memory overload. The value for `batch_size` indicates the number of documents that will be processed at once: + +```python +topic_distr, _ = topic_model.approximate_distribution(docs, batch_size=500) +``` + +### **window** +The number of tokens that are combined into token sets are defined by the `window` parameter. Seeing as we are performing a sliding window, we can change the size of the window. A larger window takes more tokens into account but setting it too large can result in considering too much information. Personally, I like to have this window between 4 and 8: + +```python +topic_distr, _ = topic_model.approximate_distribution(docs, window=4) +``` + +### **stride** +The sliding window that is performed on a document shifts, as a default, 1 token to the right each time to create its token sets. As a result, especially with large windows, a single token gets judged several times. We can use the `stride` parameter to increase the number of tokens the window shifts to the right. By increasing +this value, we are judging each token less frequently which often results in a much faster calculation. Combining this parameter with `window` is preferred. For example, if we have a very large dataset, we can set `stride=4` and `window=8` to judge token sets that contain 8 tokens but that are shifted with 4 steps +each time. As a result, this increases the computational speed quite a bit: + +```python +topic_distr, _ = topic_model.approximate_distribution(docs, window=4) +``` + +### **use_embedding_model** +As a default, we compare the c-TF-IDF calculations between the token sets and all topics. Due to its bag-of-word representation, this is quite fast. However, you might want to use the selected `embedding_model` instead to do this comparison. Do note that due to the many token sets, it is often computationally quite a bit slower: + +```python +topic_distr, _ = topic_model.approximate_distribution(docs, use_embedding_model=True) +``` diff --git a/BERTopic/docs/getting_started/distribution/distribution.png b/BERTopic/docs/getting_started/distribution/distribution.png new file mode 100644 index 0000000000000000000000000000000000000000..74e78c41242dcdead08c141a3e7ab941502cc66e Binary files /dev/null and b/BERTopic/docs/getting_started/distribution/distribution.png differ diff --git a/BERTopic/docs/getting_started/distribution/distribution_viz.html b/BERTopic/docs/getting_started/distribution/distribution_viz.html new file mode 100644 index 0000000000000000000000000000000000000000..a4b7346d168b5dc27322de84effc2c5742f857e3 --- /dev/null +++ b/BERTopic/docs/getting_started/distribution/distribution_viz.html @@ -0,0 +1,7 @@ + + + +

Although there are many ways this can be achieved, we typically use sentence-transformers (`"all-MiniLM-L6-v2"`) as it is quite capable of capturing the semantic similarity between documents. + +However, there is not one perfect +embedding model and you might want to be using something entirely different for your use case. Since BERTopic assumes some independence among steps, we can allow for this modularity: + +
+ ![Image title](embeddings.svg) +
+
+ + +This modularity allows us not only to choose any embedding model to convert our documents into numerical representations, we can use essentially any data to perform our clustering. +When new state-of-the-art pre-trained embedding models are released, BERTopic will be able to use them. As a result, BERTopic grows with any new models being released. +Out of the box, BERTopic supports several embedding techniques. In this section, we will go through several of them and how they can be implemented. + +### **Sentence Transformers** +You can select any model from sentence-transformers [here](https://www.sbert.net/docs/pretrained_models.html) +and pass it through BERTopic with `embedding_model`: + +```python +from bertopic import BERTopic +topic_model = BERTopic(embedding_model="all-MiniLM-L6-v2") +``` + +Or select a SentenceTransformer model with your parameters: + +```python +from sentence_transformers import SentenceTransformer + +sentence_model = SentenceTransformer("all-MiniLM-L6-v2") +topic_model = BERTopic(embedding_model=sentence_model) +``` + +!!! tip "Tip 1!" + This embedding back-end was put here first for a reason, sentence-transformers works amazing out of the box!

Also, make sure to frequently visit [this](https://www.sbert.net/docs/pretrained_models.html) page as new models are often released. + +!!! tip "Tip 2!" + New embedding models are released frequently and their performance keeps getting better. To keep track of the best embedding models out there, you can visit the [MTEB leaderboard](https://huggingface.co/spaces/mteb/leaderboard). It is an excellent place for selecting the embedding that works best for you. For example, if you want the best of the best, then the top 5 models might the place to look. + + Many of these models can be used with `SentenceTransformers` in BERTopic, like so: + + ```python + from sentence_transformers import SentenceTransformer + + embedding_model = SentenceTransformer("BAAI/bge-base-en-v1.5") + topic_model = BERTopic(embedding_model=embedding_model) + ``` + +### πŸ€— Hugging Face Transformers +To use a Hugging Face transformers model, load in a pipeline and point +to any model found on their model hub (https://huggingface.co/models): + +```python +from transformers.pipelines import pipeline + +embedding_model = pipeline("feature-extraction", model="distilbert-base-cased") +topic_model = BERTopic(embedding_model=embedding_model) +``` + +!!! tip "Tip!" + These transformers also work quite well using `sentence-transformers` which has great optimizations tricks that make using it a bit faster. + +### **Flair** +[Flair](https://github.com/flairNLP/flair) allows you to choose almost any embedding model that +is publicly available. Flair can be used as follows: + +```python +from flair.embeddings import TransformerDocumentEmbeddings + +roberta = TransformerDocumentEmbeddings('roberta-base') +topic_model = BERTopic(embedding_model=roberta) +``` + +You can select any πŸ€— transformers model [here](https://huggingface.co/models). + +Moreover, you can also use Flair to use word embeddings and pool them to create document embeddings. +Under the hood, Flair simply averages all word embeddings in a document. Then, we can easily +pass it to BERTopic to use those word embeddings as document embeddings: + +```python +from flair.embeddings import WordEmbeddings, DocumentPoolEmbeddings + +glove_embedding = WordEmbeddings('crawl') +document_glove_embeddings = DocumentPoolEmbeddings([glove_embedding]) + +topic_model = BERTopic(embedding_model=document_glove_embeddings) +``` + +### **Spacy** +[Spacy](https://github.com/explosion/spaCy) is an amazing framework for processing text. There are +many models available across many languages for modeling text. + +To use Spacy's non-transformer models in BERTopic: + +```python +import spacy + +nlp = spacy.load("en_core_web_md", exclude=['tagger', 'parser', 'ner', + 'attribute_ruler', 'lemmatizer']) + +topic_model = BERTopic(embedding_model=nlp) +``` + +Using spacy-transformer models: + +```python +import spacy + +spacy.prefer_gpu() +nlp = spacy.load("en_core_web_trf", exclude=['tagger', 'parser', 'ner', + 'attribute_ruler', 'lemmatizer']) + +topic_model = BERTopic(embedding_model=nlp) +``` + +If you run into memory issues with spacy-transformer models, try: + +```python +import spacy +from thinc.api import set_gpu_allocator, require_gpu + +nlp = spacy.load("en_core_web_trf", exclude=['tagger', 'parser', 'ner', + 'attribute_ruler', 'lemmatizer']) +set_gpu_allocator("pytorch") +require_gpu(0) + +topic_model = BERTopic(embedding_model=nlp) +``` + +### **Universal Sentence Encoder (USE)** +The Universal Sentence Encoder encodes text into high-dimensional vectors that are used here +for embedding the documents. The model is trained and optimized for greater-than-word length text, +such as sentences, phrases, or short paragraphs. + +Using USE in BERTopic is rather straightforward: + +```python +import tensorflow_hub +embedding_model = tensorflow_hub.load("https://tfhub.dev/google/universal-sentence-encoder/4") +topic_model = BERTopic(embedding_model=embedding_model) +``` + +### **Gensim** +BERTopic supports the `gensim.downloader` module, which allows it to download any word embedding model supported by Gensim. +Typically, these are Glove, Word2Vec, or FastText embeddings: + +```python +import gensim.downloader as api +ft = api.load('fasttext-wiki-news-subwords-300') +topic_model = BERTopic(embedding_model=ft) +``` + +!!! tip "Tip!" + Gensim is primarily used for Word Embedding models. This works typically best for short documents since the word embeddings are pooled. + + +### **Scikit-Learn Embeddings** +Scikit-Learn is a framework for more than just machine learning. +It offers many preprocessing tools, some of which can be used to create representations +for text. Many of these tools are relatively lightweight and do not require a GPU. +While the representations may be less expressive than many BERT models, the fact that +it runs much faster can make it a relevant candidate to consider. + +If you have a scikit-learn compatible pipeline that you'd like to use to embed +text then you can also pass this to BERTopic. + +```python +from sklearn.pipeline import make_pipeline +from sklearn.decomposition import TruncatedSVD +from sklearn.feature_extraction.text import TfidfVectorizer + +pipe = make_pipeline( + TfidfVectorizer(), + TruncatedSVD(100) +) + +topic_model = BERTopic(embedding_model=pipe) +``` + +!!! Warning + One caveat to be aware of is that scikit-learns base `Pipeline` class does not + support the `.partial_fit()`-API. If you have a pipeline that theoretically should + be able to support online learning then you might want to explore + the [scikit-partial](https://github.com/koaning/scikit-partial) project. + Moreover, since this backend does not generate representations on a word level, + it does not support the `bertopic.representation` models. + + +### OpenAI +To use OpenAI's external API, we need to define our key and explicitly call `bertopic.backend.OpenAIBackend` +to be used in our topic model: + +```python +import openai +from bertopic.backend import OpenAIBackend + +client = openai.OpenAI(api_key="sk-...") +embedding_model = OpenAIBackend(client, "text-embedding-ada-002") + +topic_model = BERTopic(embedding_model=embedding_model) +``` + + +### Cohere +To use Cohere's external API, we need to define our key and explicitly call `bertopic.backend.CohereBackend` +to be used in our topic model: + +```python +import cohere +from bertopic.backend import CohereBackend + +client = cohere.Client("MY_API_KEY") +embedding_model = CohereBackend(client) + +topic_model = BERTopic(embedding_model=embedding_model) +``` + +### Multimodal +To create embeddings for both text and images in the same vector space, we can use the `MultiModalBackend`. +This model uses a clip-vit based model that is capable of embedding text, images, or both: + +```python +from bertopic.backend import MultiModalBackend +model = MultiModalBackend('clip-ViT-B-32', batch_size=32) + +# Embed documents only +doc_embeddings = model.embed_documents(docs) + +# Embeding images only +image_embeddings = model.embed_images(images) + +# Embed both images and documents, then average them +doc_image_embeddings = model.embed(docs, images) +``` + + +### **Custom Backend** +If your backend or model cannot be found in the ones currently available, you can use the `bertopic.backend.BaseEmbedder` class to +create your backend. Below, you will find an example of creating a SentenceTransformer backend for BERTopic: + +```python +from bertopic.backend import BaseEmbedder +from sentence_transformers import SentenceTransformer + +class CustomEmbedder(BaseEmbedder): + def __init__(self, embedding_model): + super().__init__() + self.embedding_model = embedding_model + + def embed(self, documents, verbose=False): + embeddings = self.embedding_model.encode(documents, show_progress_bar=verbose) + return embeddings + +# Create custom backend +embedding_model = SentenceTransformer("all-MiniLM-L6-v2") +custom_embedder = CustomEmbedder(embedding_model=embedding_model) + +# Pass custom backend to bertopic +topic_model = BERTopic(embedding_model=custom_embedder) +``` + +### **Custom Embeddings** +The base models in BERTopic are BERT-based models that work well with document similarity tasks. Your documents, +however, might be too specific for a general pre-trained model to be used. Fortunately, you can use the embedding +model in BERTopic to create document features. + +You only need to prepare the document embeddings yourself and pass them through `fit_transform` of BERTopic: +```python +from sklearn.datasets import fetch_20newsgroups +from sentence_transformers import SentenceTransformer + +# Prepare embeddings +docs = fetch_20newsgroups(subset='all', remove=('headers', 'footers', 'quotes'))['data'] +sentence_model = SentenceTransformer("all-MiniLM-L6-v2") +embeddings = sentence_model.encode(docs, show_progress_bar=False) + +# Train our topic model using our pre-trained sentence-transformers embeddings +topic_model = BERTopic() +topics, probs = topic_model.fit_transform(docs, embeddings) +``` + +As you can see above, we used a SentenceTransformer model to create the embedding. You could also have used +`πŸ€— transformers`, `Doc2Vec`, or any other embedding method. + +#### **TF-IDF** +As mentioned above, any embedding technique can be used. However, when running UMAP, the typical distance metric is +`cosine` which does not work quite well for a TF-IDF matrix. Instead, BERTopic will recognize that a sparse matrix +is passed and use `hellinger` instead which works quite well for the similarity between probability distributions. + +We simply create a TF-IDF matrix and use them as embeddings in our `fit_transform` method: + +```python +from sklearn.datasets import fetch_20newsgroups +from sklearn.feature_extraction.text import TfidfVectorizer + +# Create TF-IDF sparse matrix +docs = fetch_20newsgroups(subset='all', remove=('headers', 'footers', 'quotes'))['data'] +vectorizer = TfidfVectorizer(min_df=5) +embeddings = vectorizer.fit_transform(docs) + +# Train our topic model using TF-IDF vectors +topic_model = BERTopic(stop_words="english") +topics, probs = topic_model.fit_transform(docs, embeddings) +``` + +Here, you will probably notice that creating the embeddings is quite fast whereas `fit_transform` is quite slow. +This is to be expected as reducing the dimensionality of a large sparse matrix takes some time. The inverse of using +transformer embeddings is true: creating the embeddings is slow whereas `fit_transform` is quite fast. diff --git a/BERTopic/docs/getting_started/embeddings/embeddings.svg b/BERTopic/docs/getting_started/embeddings/embeddings.svg new file mode 100644 index 0000000000000000000000000000000000000000..a982c53f99b3e44d485f624b1c634f415903fba9 --- /dev/null +++ b/BERTopic/docs/getting_started/embeddings/embeddings.svg @@ -0,0 +1,105 @@ + + + + + + +SpaCy + + + + + +SBERT + + + + + +Transformers + + + + + + + + + + + + + + + + + + + + + + + + +UMAP + + + + + +HDBSCAN + + + + + +CountVectorizer + + + + + +c-TF-IDF + + + + + +Optional Fine-tuning + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + diff --git a/BERTopic/docs/getting_started/guided/guided.md b/BERTopic/docs/getting_started/guided/guided.md new file mode 100644 index 0000000000000000000000000000000000000000..9233ac41e2811777a1830688d99d5d30112ee1b4 --- /dev/null +++ b/BERTopic/docs/getting_started/guided/guided.md @@ -0,0 +1,48 @@ +Guided Topic Modeling or Seeded Topic Modeling is a collection of techniques that guides the topic modeling approach by setting several seed topics to which the model will converge to. These techniques allow the user to set a predefined number of topic representations that are sure to be in documents. For example, take an IT business that has a ticket system for the software their clients use. Those tickets may typically contain information about a specific bug regarding login issues that the IT business is aware of. + +To model that bug, we can create a seed topic representation containing the words `bug`, `login`, `password`, +and `username`. By defining those words, a Guided Topic Modeling approach will try to converge at least one topic to those words. + +
+

+
+ +Guided BERTopic has two main steps: + +First, we create embeddings for each seeded topic by joining them and passing them through the document embedder. These embeddings will be compared with the existing document embeddings through cosine similarity and assigned a label. If the document is most similar to a seeded topic, then it will get that topic's label. +If it is most similar to the average document embedding, it will get the -1 label. +These labels are then passed through UMAP to create a semi-supervised approach that should nudge +the topic creation to the seeded topics. + +Second, we take all words in seed_topic_list and assign them a multiplier larger than 1. +Those multipliers will be used to increase the IDF values of the words across all topics thereby increasing +the likelihood that a seeded topic word will appear in a topic. This does, however, also increase the chance of an irrelevant topic having unrelated words. In practice, this should not be an issue since the IDF value is likely to remain low regardless of the multiplier. The multiplier is now a fixed value but may change to something more elegant, like taking the distribution of IDF values and its position into account when defining the multiplier. + +### **Example** +To demonstrate Guided BERTopic, we use the 20 Newsgroups dataset as our example. We have frequently used this +dataset in BERTopic examples and we sometimes see a topic generated about health with words such as `drug` and `cancer` +being important. However, due to the stochastic nature of UMAP, this topic is not always found. + +In order to guide BERTopic to that topic, we create a seed topic list that we pass through our model.

+ +In BERTopic, we can approximate this potential hierarchy by making use of our topic-term matrix (c-TF-IDF matrix). This matrix contains information about the importance of every word in every topic and makes for a nice numerical representation of our topics. The smaller the distance between two c-TF-IDF representations, the more similar we assume they are. In practice, this process of merging topics is done through the hierarchical clustering capabilities of `scipy` (see [here](https://docs.scipy.org/doc/scipy/reference/cluster.hierarchy.html)). It allows for several linkage methods through which we can approximate our topic hierarchy. As a default, we are using the [ward](https://docs.scipy.org/doc/scipy/reference/generated/scipy.cluster.hierarchy.ward.html#scipy.cluster.hierarchy.ward) but many others are available. + +Whenever we merge two topics, we can calculate the c-TF-IDF representation of these two merged by summing their bag-of-words representation.

+ ![Image title](images_only.svg) +
+
+ +To run BERTopic on images only, we first need to embed our images and then define a model that convert images to text. To do so, we are going to need some images. We will take the same images as the above but instead save them locally and pass the paths to the images instead.

Essentially, it is a way to update your topic model with data on which it was not trained before. In Scikit-Learn, this technique is often modeled through a `.partial_fit` function, which is also used in BERTopic. + +!!! Tip + Another method for online topic modeling can be found with the [**.merge_models**](https://maartengr.github.io/BERTopic/getting_started/merge/merge.html) functionality of BERTopic. It allows for merging multiple BERTopic models to create a single new one. This method can be used to discover new topics by training a new model and exploring whether that new model added new topics to the original model when merging. A major benefit, compared to `.partial_fit` is that you can keep using the original UMAP and HDBSCAN models which tends result in improved performance and gives you significant more flexibility. + +In BERTopic, there are three main goals for using this technique. + +* To reduce the memory necessary for training a topic model. +* To continuously update the topic model as new data comes in. +* To continuously find new topics as new data comes in. + +In BERTopic, online topic modeling can be a bit tricky as there are several steps involved in which online learning needs to be made available. To recap, BERTopic consists of the following 6 steps: + +1. Extract embeddings +2. Reduce dimensionality +3. Cluster reduced embeddings +4. Tokenize topics +5. Extract topic words +6. (Optional) Fine-tune topic words + +For some steps, an online variant is more important than others. Typically, in step 1 we use pre-trained language models that are in less need of continuous updates. This means that we can use an embedding model like Sentence-Transformers for extracting the embeddings and still use it in an online setting. Similarly, steps 5 and 6 do not necessarily need online variants since they are built upon step 4, tokenization. If that tokenization is by itself incremental, then so will steps 5 and 6. + +
+
+--8<-- "docs/getting_started/online/online.svg" +
+
+ +This means that we will need online variants for steps 2 through 4. Steps 2 and 3, dimensionality reduction and clustering, can be modeled through the use of Scikit-Learn's `.partial_fit` function. In other words, it supports any algorithm that can be trained using `.partial_fit` since these algorithms can be trained incrementally. For example, incremental dimensionality reduction can be achieved using Scikit-Learn's `IncrementalPCA` and incremental clustering with `MiniBatchKMeans`. + +Lastly, we need to develop an online variant for step 5, tokenization. In this step, a Bag-of-words representation is created through the `CountVectorizer`. However, as new data comes in, its vocabulary will need to be updated. For that purpose, `bertopic.vectorizers.OnlineCountVectorizer` was created that not only updates out-of-vocabulary words but also implements decay and cleaning functions to prevent the sparse bag-of-words matrix to become too large. Most notably, the `decay` parameter is a value between 0 and 1 to weigh the percentage of frequencies that the previous bag-of-words matrix should be reduced to. For example, a value of `.1` will decrease the frequencies in the bag-of-words matrix by 10% at each iteration. This will make sure that recent data has more weight than previous iterations. Similarly, `delete_min_df` will remove certain words from its vocabulary if their frequency is lower than a set value. This ties together with the `decay` parameter as some words will decay over time if not used. For more information regarding the `OnlineCountVectorizer`, please see the [vectorizers documentation](https://maartengr.github.io/BERTopic/getting_started/vectorizers/vectorizers.html#onlinecountvectorizer). + + + +## **Example** + +Online topic modeling in BERTopic is rather straightforward. We first need to have our documents split into chunks such that we can train and update our topic model incrementally. + +```python +from sklearn.datasets import fetch_20newsgroups + +# Prepare documents +all_docs = fetch_20newsgroups(subset=subset, remove=('headers', 'footers', 'quotes'))["data"] +doc_chunks = [all_docs[i:i+1000] for i in range(0, len(all_docs), 1000)] +``` + +Here, we created chunks of 1000 documents to be fed in BERTopic. Then, we will need to define several sub-models that support online learning. Specifically, we are going to be using `IncrementalPCA`, `MiniBatchKMeans`, and the `OnlineCountVectorizer`: + +```python +from sklearn.cluster import MiniBatchKMeans +from sklearn.decomposition import IncrementalPCA +from bertopic.vectorizers import OnlineCountVectorizer + +# Prepare sub-models that support online learning +umap_model = IncrementalPCA(n_components=5) +cluster_model = MiniBatchKMeans(n_clusters=50, random_state=0) +vectorizer_model = OnlineCountVectorizer(stop_words="english", decay=.01) +``` + +After having defined our sub-models, we can start training our topic model incrementally by looping over our document chunks: + +```python +from bertopic import BERTopic + +topic_model = BERTopic(umap_model=umap_model, + hdbscan_model=cluster_model, + vectorizer_model=vectorizer_model) + +# Incrementally fit the topic model by training on 1000 documents at a time +for docs in doc_chunks: + topic_model.partial_fit(docs) +``` + +And that is it! During each iteration, you can access the predicted topics through the `.topics_` attribute. + +!!! note + Do note that in BERTopic it is not possible to use `.partial_fit` after the `.fit` as they work quite differently concerning internally updating topics, frequencies, representations, etc. + +!!! tip Tip + You can use any other dimensionality reduction and clustering algorithm as long as they have a `.partial_fit` function. Moreover, you can use dimensionality reduction algorithms that do not support `.partial_fit` functions but do have a `.fit` function to first train it on a large amount of data and then continuously add documents. The dimensionality reduction will not be updated but may be trained sufficiently to properly reduce the embeddings without the need to continuously add documents. + +!!! warning + Only the most recent batch of documents is tracked. If you want to be using online topic modeling for low-memory use cases, then it is advised to also update the `.topics_` attribute. Otherwise, variations such as **hierarchical topic modeling** will not work. + + ```python + # Incrementally fit the topic model by training on 1000 documents at a time and track the topics in each iteration + topics = [] + for docs in doc_chunks: + topic_model.partial_fit(docs) + topics.extend(topic_model.topics_) + + topic_model.topics_ = topics + ``` + + +## **River** + +To continuously find new topics as they come in, we can use the package [river](https://github.com/online-ml/river). It contains several clustering models that can create new clusters as new data comes in. To make sure we can use their models, we first need to create a class that has a `.partial_fit` function and the option to extract labels through `.labels_`: + +```python +from river import stream +from river import cluster + +class River: + def __init__(self, model): + self.model = model + + def partial_fit(self, umap_embeddings): + for umap_embedding, _ in stream.iter_array(umap_embeddings): + self.model = self.model.learn_one(umap_embedding) + + labels = [] + for umap_embedding, _ in stream.iter_array(umap_embeddings): + label = self.model.predict_one(umap_embedding) + labels.append(label) + + self.labels_ = labels + return self +``` + +Then, we can choose any `river.cluster` model that we are interested in and pass it to the `River` class before using it in BERTopic: + +```python +# Using DBSTREAM to detect new topics as they come in +cluster_model = River(cluster.DBSTREAM()) +vectorizer_model = OnlineCountVectorizer(stop_words="english") +ctfidf_model = ClassTfidfTransformer(reduce_frequent_words=True, bm25_weighting=True) + +# Prepare model +topic_model = BERTopic( + hdbscan_model=cluster_model, + vectorizer_model=vectorizer_model, + ctfidf_model=ctfidf_model, +) + + +# Incrementally fit the topic model by training on 1000 documents at a time +for docs in doc_chunks: + topic_model.partial_fit(docs) +``` \ No newline at end of file diff --git a/BERTopic/docs/getting_started/online/online.svg b/BERTopic/docs/getting_started/online/online.svg new file mode 100644 index 0000000000000000000000000000000000000000..e3ab13e092eabf5b51309329cd576f187a682de5 --- /dev/null +++ b/BERTopic/docs/getting_started/online/online.svg @@ -0,0 +1,26 @@ + + + +SBERT +IncrementalPCA +MiniBatchKMeans +Online CountVectorizer +Embeddings + +Dimensionality reduction + + +Clustering + + +Incremental Bag-of-Words + +c-TF-IDF + +Topic representation + + +Online variants of these steps in the main BERTopic pipeline are needed in order to enable incremental learning. + + + diff --git a/BERTopic/docs/getting_started/outlier_reduction/fig_base.html b/BERTopic/docs/getting_started/outlier_reduction/fig_base.html new file mode 100644 index 0000000000000000000000000000000000000000..b1964816e8cbecf444fdea7937898f9596ea9ecd --- /dev/null +++ b/BERTopic/docs/getting_started/outlier_reduction/fig_base.html @@ -0,0 +1,7 @@ + + + +

Is it matched to topic 1 or 2. + + +### **Update Topic Representation** + +When outlier documents are generated, they are not used when modeling the topic representations. These documents are completely ignored when finding good descriptions of topics. Thus, after having reduced the number of outliers in your topic model, you might want to update the topic representations with the documents that now belong to actual topics.

In this section, we will go through the most impactful parameters in BERTopic and directions on how to optimize them. + +### **language** +The `language` parameter is used to simplify the selection of models for those who are not familiar with sentence-transformers models. + +In essence, there are two options to choose from: + +* `language = "english"` or +* `language = "multilingual"` + +The English model is "all-MiniLM-L6-v2" and can be found [here](https://www.sbert.net/docs/pretrained_models.html). It is the default model that is used in BERTopic and works great for English documents. + +The multilingual model is "paraphrase-multilingual-MiniLM-L12-v2" and supports over 50+ languages which can be found [here](https://www.sbert.net/docs/pretrained_models.html). The model is very similar to the base model but is trained on many languages and has a slightly different architecture. + +### **top_n_words** + +`top_n_words` refers to the number of words per topic that you want to be extracted. In practice, I would advise you to keep this value below 30 and preferably between 10 and 20. The reasoning for this is that the more words you put in a topic the less coherent it can become. The top words are the most representative of the topic and should be focused on. + +### **n_gram_range** +The `n_gram_range` parameter refers to the CountVectorizer used when creating the topic representation. It relates to the number of words you want in your topic representation. For example, "New" and "York" are two separate words but are often used as "New York" which represents an n-gram of 2. Thus, the `n_gram_range` should be set to (1, 2) if you want "New York" in your topic representation. + +### **min_topic_size** +`min_topic_size` is an important parameter! It is used to specify what the minimum size of a topic can be. The lower this value the more topics are created. If you set this value too high, then it is possible that simply no topics will be created! Set this value too low and you will get many microclusters. + +It is advised to play around with this value depending on the size of your dataset. If it nears a million documents, then it is advised to set it much higher than the default of 10, for example, 100 or even 500. + +### **nr_topics** +`nr_topics` can be a tricky parameter. It specifies, after training the topic model, the number of topics that will be reduced. For example, if your topic model results in 100 topics but you have set `nr_topics` to 20 then the topic model will try to reduce the number of topics from 100 to 20. + +This reduction can take a while as each reduction in topics activates a c-TF-IDF calculation. If this is set to None, no reduction is applied. Use "auto" to automatically reduce topics using HDBSCAN. + +### **low_memory** +`low_memory` sets UMAP's `low_memory` to True to make sure that less memory is used in the computation. This slows down computation but allows UMAP to be run on low-memory machines. + +### **calculate_probabilities** +`calculate_probabilities` lets you calculate the probabilities of each topic in each document. This is computationally quite expensive and is turned off by default. + +## **UMAP** + +UMAP is an amazing technique for dimensionality reduction. In BERTopic, it is used to reduce the dimensionality of document embedding into something easier to use with HDBSCAN to create good clusters. + +However, it does has a significant number of parameters you could take into account. As exposing all parameters in BERTopic would be difficult to manage, we can instantiate our UMAP model and pass it to BERTopic: + +```python +from umap import UMAP + +umap_model = UMAP(n_neighbors=15, n_components=10, metric='cosine', low_memory=False) +topic_model = BERTopic(umap_model=umap_model).fit(docs) +``` + +### **n_neighbors** +`n_neighbors` is the number of neighboring sample points used when making the manifold approximation. Increasing this value typically results in a +more global view of the embedding structure whilst smaller values result in a more local view. Increasing this value often results in larger clusters +being created. + +### **n_components** +`n_components` refers to the dimensionality of the embeddings after reducing them. This is set as a default to `5` to reduce dimensionality +as much as possible whilst trying to maximize the information kept in the resulting embeddings. Although lowering or increasing this value influences the quality of embeddings, its effect is largest on the performance of HDBSCAN. Increasing this value too much and HDBSCAN will have a +hard time clustering the high-dimensional embeddings. Lower this value too much and too little information in the resulting embeddings are available +to create proper clusters. If you want to increase this value, I would advise setting using a metric for HDBSCAN that works well in high dimensional data. + +### **metric** +`metric` refers to the method used to compute the distances in high dimensional space. The default is `cosine` as we are dealing with high dimensional data. However, BERTopic is also able to use any input, even regular tabular data, to cluster the documents. Thus, you might want to change the metric +to something that fits your use case. + +### **low_memory** +`low_memory` is used when datasets may consume a lot of memory. Using millions of documents can lead to memory issues and setting this value to `True` +might alleviate some of the issues. + +## **HDBSCAN** +After reducing the embeddings with UMAP, we use HDBSCAN to cluster our documents into clusters of similar documents. Similar to UMAP, HDBSCAN has many parameters that could be tweaked to improve the cluster's quality. + +```python +from hdbscan import HDBSCAN + +hdbscan_model = HDBSCAN(min_cluster_size=10, metric='euclidean', prediction_data=True) +topic_model = BERTopic(hdbscan_model=hdbscan_model).fit(docs) +``` + +### **min_cluster_size** +`min_cluster_size` is arguably the most important parameter in HDBSCAN. It controls the minimum size of a cluster and thereby the number of clusters +that will be generated. It is set to `10` as a default. Increasing this value results in fewer clusters but of larger size whereas decreasing this value +results in more micro clusters being generated. Typically, I would advise increasing this value rather than decreasing it. + +### **min_samples** +`min_samples` is automatically set to `min_cluster_size` and controls the number of outliers generated. Setting this value significantly lower than +`min_cluster_size` might help you reduce the amount of noise you will get. Do note that outliers are to be expected and forcing the output +to have no outliers may not properly represent the data. + +### **metric** +`metric`, like with HDBSCAN is used to calculate the distances.

Here, we are going to focus on text generation Large Language Models such as ChatGPT, GPT-4, and open-source solutions. + +Using these techniques, we can further fine-tune topics to generate labels, summaries, poems of topics, and more. To do so, we first generate a set of keywords and documents that describe a topic best using BERTopic's c-TF-IDF calculate.

The prompts that were generated after training can be accessed with `topic_model.representation_model.prompts_`. + +### **Selecting Documents** + +By default, four of the most representative documents will be passed to `[DOCUMENTS]`. These documents are selected by calculating their similarity (through c-TF-IDF representations) with the main c-TF-IDF representation of the topics. The four best matching documents per topic are selected. + +To increase the number of documents passed to `[DOCUMENTS]`, we can use the `nr_docs` parameter which is accessible in all LLMs on this page. Using this value allows you to select the top *n* most representative documents instead. If you have a long enough context length, then you could even give the LLM dozens of documents. + +However, some of these documents might be very similar to one another and might be near duplicates. They will not provide much additional information about the content of the topic. Instead, we can use the `diversity` parameter in each LLM to only select documents that are sufficiently diverse. It takes values between 0 and 1 but a value of 0.1 already does wonders! + +### **Truncating Documents** + +We can truncate the input documents in `[DOCUMENTS]` in order to reduce the number of tokens that we have in our input prompt. To do so, all text generation modules have two parameters that we can tweak: + +* `doc_length` + * The maximum length of each document. If a document is longer, it will be truncated. If None, the entire document is passed. +* `tokenizer` + * The tokenizer used to calculate to split the document into segments used to count the length of a document. + * If tokenizer is `'char'`, then the document is split up into characters which are counted to adhere to `doc_length` + * If tokenizer is `'whitespace'`, the document is split up into words separated by whitespaces. These words are counted and truncated depending on `doc_length` + * If tokenizer is `'vectorizer'`, then the internal CountVectorizer is used to tokenize the document. These tokens are counted and trunctated depending on `doc_length` + * If tokenizer is a callable, then that callable is used to tokenized the document. These tokens are counted and truncated depending on `doc_length` + +This means that the definition of `doc_length` changes depending on what constitutes a token in the `tokenizer` parameter. If a token is a character, then `doc_length` refers to max length in characters. If a token is a word, then `doc_length` refers to the max length in words. + +Let's illustrate this with an example. In the code below, we will use [`tiktoken`](https://github.com/openai/tiktoken) to count the number of tokens in each document and limit them to 100 tokens. All documents that have more than 100 tokens will be truncated. + +We start by installing the relevant packages: + +```bash +pip install tiktoken openai +``` + +Then, we use `bertopic.representation.OpenAI` to represent our topics with nicely written labels. We specify that documents that we put in the prompt cannot exceed 100 tokens each. Since we will put 4 documents in the prompt, they will total roughly 400 tokens: + +```python +import openai +import tiktoken +from bertopic.representation import OpenAI +from bertopic import BERTopic + +# Tokenizer +tokenizer= tiktoken.encoding_for_model("gpt-3.5-turbo") + +# Create your representation model +client = openai.OpenAI(api_key="sk-...") +representation_model = OpenAI( + client, + model="gpt-3.5-turbo", + delay_in_seconds=2, + chat=True, + nr_docs=4, + doc_length=100, + tokenizer=tokenizer +) + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +## **πŸ€— Transformers** + +Nearly every week, there are new and improved models released on the πŸ€— [Model Hub](https://huggingface.co/models) that, with some creativity, allow for +further fine-tuning of our c-TF-IDF based topics. These models range from text generation to zero-classification. In BERTopic, wrappers around these +methods are created as a way to support whatever might be released in the future. + +Using a GPT-like model from the huggingface hub is rather straightforward: + +```python +from bertopic.representation import TextGeneration +from bertopic import BERTopic + +# Create your representation model +representation_model = TextGeneration('gpt2') + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +GPT2, however, is not the most accurate model out there on HuggingFace models. You can get +much better results with a `flan-T5` like model: + +```python +from transformers import pipeline +from bertopic.representation import TextGeneration + +prompt = "I have a topic described by the following keywords: [KEYWORDS]. Based on the previous keywords, what is this topic about?" + +# Create your representation model +generator = pipeline('text2text-generation', model='google/flan-t5-base') +representation_model = TextGeneration(generator) +``` + +
+
+--8<-- "docs/getting_started/representation/hf.svg" +
+
+ +As can be seen from the example above, if you would like to use a `text2text-generation` model, you will to +pass a `transformers.pipeline` with the `"text2text-generation"` parameter. Moreover, you can use a custom prompt and decide where the keywords should +be inserted by using the `[KEYWORDS]` or documents with the `[DOCUMENTS]` tag. + +### **Zephyr** (Mistral 7B) + +We can go a step further with open-source Large Language Models (LLMs) that have shown to match the performance of closed-source LLMs like ChatGPT. + +In this example, we will show you how to use Zephyr, a fine-tuning version of Mistral 7B. Mistral 7B outperforms other open-source LLMs at a much smaller scale and is a worthwhile solution for use cases such as topic modeling. We want to keep inference as fast as possible and a relatively small model helps with that. Zephyr is a fine-tuned version of Mistral 7B that was trained on a mix of publicly available and synthetic datasets using Direct Preference Optimization (DPO). + +To use Zephyr in BERTopic, we will first need to install and update a couple of packages that can handle quantized versions of Zephyr: + +```python +pip install ctransformers[cuda] +pip install --upgrade git+https://github.com/huggingface/transformers +``` + +Instead of loading in the full model, we can instead load a quantized model which is a compressed version of the original model: + +```python +from ctransformers import AutoModelForCausalLM +from transformers import AutoTokenizer, pipeline + +# Set gpu_layers to the number of layers to offload to GPU.

components of BERTopic is its Bag-of-Words representation and weighting with c-TF-IDF.

Although we can use a centroid-based +technique for this, it can be costly and does not take the structure of a cluster into account. Instead, we leverage +c-TF-IDF to create a set of representative documents per topic and use those as our updated topic embedding. Then, we calculate +the similarity between candidate keywords and the topic embedding using the same embedding model that embedded the documents. + +
+
+--8<-- "docs/getting_started/representation/keybertinspired.svg" +
+
+ +Thus, the algorithm follows some principles of [KeyBERT](https://github.com/MaartenGr/KeyBERT) but does some optimization in +order to speed up inference. Usage is straightforward: + +```python +from bertopic.representation import KeyBERTInspired +from bertopic import BERTopic + +# Create your representation model +representation_model = KeyBERTInspired() + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +
+
+--8<-- "docs/getting_started/representation/keybert.svg" +
+
+ +## **PartOfSpeech** +Our candidate topics, as extracted with c-TF-IDF, do not take into account a keyword's part of speech as extracting noun-phrases from +all documents can be computationally quite expensive. Instead, we can leverage c-TF-IDF to perform part of speech on a subset of +keywords and documents that best represent a topic. + +
+
+--8<-- "docs/getting_started/representation/partofspeech.svg" +
+
+ +More specifically, we find documents that contain the keywords from our candidate topics as calculated with c-TF-IDF. These documents serve +as the representative set of documents from which the Spacy model can extract a set of candidate keywords for each topic. +These candidate keywords are first put through Spacy's POS module to see whether they match with the `DEFAULT_PATTERNS`: + +```python +DEFAULT_PATTERNS = [ + [{'POS': 'ADJ'}, {'POS': 'NOUN'}], + [{'POS': 'NOUN'}], + [{'POS': 'ADJ'}] +] +``` + +These patterns follow Spacy's [Rule-Based Matching](https://spacy.io/usage/rule-based-matching). Then, the resulting keywords are sorted by +their respective c-TF-IDF values. + +```python +from bertopic.representation import PartOfSpeech +from bertopic import BERTopic + +# Create your representation model +representation_model = PartOfSpeech("en_core_web_sm") + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +
+
+--8<-- "docs/getting_started/representation/pos.svg" +
+
+ +You can define custom POS patterns to be extracted: + +```python +pos_patterns = [ + [{'POS': 'ADJ'}, {'POS': 'NOUN'}], + [{'POS': 'NOUN'}], [{'POS': 'ADJ'}] +] +representation_model = PartOfSpeech("en_core_web_sm", pos_patterns=pos_patterns) +``` + + +## **MaximalMarginalRelevance** +When we calculate the weights of keywords, we typically do not consider whether we already have similar keywords in our topic. Words like "car" and "cars" +essentially represent the same information and often redundant. + +
+
+--8<-- "docs/getting_started/representation/mmr.svg" +
+
+ + + +To decrease this redundancy and improve the diversity of keywords, we can use an algorithm called Maximal Marginal Relevance (MMR). MMR considers the similarity of keywords/keyphrases with the document, along with the similarity of already selected keywords and keyphrases. This results in a selection of keywords +that maximize their within diversity with respect to the document. + + +```python +from bertopic.representation import MaximalMarginalRelevance +from bertopic import BERTopic + +# Create your representation model +representation_model = MaximalMarginalRelevance(diversity=0.3) + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +
+
+--8<-- "docs/getting_started/representation/mmr_output.svg" +
+
+ +## **Zero-Shot Classification** + +For some use cases, you might already have a set of candidate labels that you would like to automatically assign to some of the topics. +Although we can use guided or supervised BERTopic for that, we can also use zero-shot classification to assign labels to our topics. +For that, we can make use of πŸ€— transformers on their models on the [model hub](https://huggingface.co/models?pipeline_tag=zero-shot-classification&sort=downloads). + +To perform this classification, we feed the model with the keywords as generated through c-TF-IDF and a set of candidate labels. +If, for a certain topic, we find a similar enough label, then it is assigned. If not, then we keep the original c-TF-IDF keywords. + +We use it in BERTopic as follows: + +```python +from bertopic.representation import ZeroShotClassification +from bertopic import BERTopic + +# Create your representation model +candidate_topics = ["space and nasa", "bicycles", "sports"] +representation_model = ZeroShotClassification(candidate_topics, model="facebook/bart-large-mnli") + +# Use the representation model in BERTopic on top of the default pipeline +topic_model = BERTopic(representation_model=representation_model) +``` + +
+
+--8<-- "docs/getting_started/representation/zero.svg" +
+
+ +## **Chain Models** + +All of the above models can make use of the candidate topics, as generated by c-TF-IDF, to further fine-tune the topic representations. For example, `MaximalMarginalRelevance` takes the keywords in the candidate topics and re-ranks them. Similarly, the keywords in the candidate topic can be used as the input for GPT-prompts in `OpenAI`. + +Although the default candidate topics are generated by c-TF-IDF, what if we were to chain these models? For example, we can use `MaximalMarginalRelevance` to improve upon the keywords in each topic before passing them to `OpenAI`. + +This is supported in BERTopic by simply passing a list of representation models when instantation the topic model: + +```python +from bertopic.representation import MaximalMarginalRelevance, OpenAI +from bertopic import BERTopic +import openai + +# Create your representation models +client = openai.OpenAI(api_key="sk-...") +openai_generator = OpenAI(client) +mmr = MaximalMarginalRelevance(diversity=0.3) +representation_models = [mmr, openai_generator] + +# Use the chained models +topic_model = BERTopic(representation_model=representation_models) +``` + +## **Custom Model** + +Although several representation models have been implemented in BERTopic, new technologies get released often and we should not have to wait until they get implemented in BERTopic. Therefore, you can create your own representation model and use that to fine-tune the topics. + +The following is the basic structure for creating your custom model. Note that it returns the same topics as the those +calculated with c-TF-IDF: + +```python +from bertopic.representation._base import BaseRepresentation + + +class CustomRepresentationModel(BaseRepresentation): + def extract_topics(self, topic_model, documents, c_tf_idf, topics + ) -> Mapping[str, List[Tuple[str, float]]]: + """ Extract topics + + Arguments: + topic_model: The BERTopic model + documents: A dataframe of documents with their related topics + c_tf_idf: The c-TF-IDF matrix + topics: The candidate topics as calculated with c-TF-IDF + + Returns: + updated_topics: Updated topic representations + """ + updated_topics = topics.copy() + return updated_topics +``` + +Then, we can use that model as follows: + +```python +from bertopic import BERTopic + +# Create our custom representation model +representation_model = CustomRepresentationModel() + +# Pass our custom representation model to BERTopic +topic_model = BERTopic(representation_model=representation_model) +``` + +There are a few things to take into account when creating your custom model: + +* It needs to have the exact same parameter input: `topic_model`, `documents`, `c_tf_idf`, `topics`. +* Make sure that `updated_topics` has the exact same structure as `topics`: + +```python +updated_topics = { + "1", [("space", 0.9), ("nasa", 0.7)], + "2": [("science", 0.66), ("article", 0.6)] +} +``` + +!!!

Using the `ClassTfidfTransformer`, we can define those `seed_words` and also choose by how much their values are multiplied. + +The full example is then as follows: + +```python +from umap import UMAP +from datasets import load_dataset +from bertopic import BERTopic +from bertopic.vectorizers import ClassTfidfTransformer + +# Let's take a subset of ArXiv abstracts as the training data +dataset = load_dataset("CShorten/ML-ArXiv-Papers")["train"] +abstracts = dataset["abstract"][:5_000] + +# For illustration purposes, we make sure the output is fixed when running this code multiple times +umap_model = UMAP(n_neighbors=15, n_components=5, min_dist=0.0, metric='cosine', random_state=42) + +# We can choose any number of seed words for which we want their representation +# to be strengthen. We increase the importance of these words as we want them to be more +# likely to end up in the topic representations. +ctfidf_model = ClassTfidfTransformer( + seed_words=["agent", "robot", "behavior", "policies", "environment"], + seed_multiplier=2 +) + +# We run the topic model with the seeded words +topic_model = BERTopic( + umap_model=umap_model, + min_topic_size=15, + ctfidf_model=ctfidf_model, +).fit(abstracts) +``` + +Then, when we run `topic_model.get_topic(0)`, we get the following output: + +```python +[('policy', 0.023413102511982354), + ('reinforcement', 0.021796126795834238), + ('agent', 0.021131601305431902), + ('policies', 0.01888385271486409), + ('environment', 0.017819874593917057), + ('learning', 0.015321710504308708), + ('robot', 0.013881115279230468), + ('control', 0.013297705894983875), + ('the', 0.013247933839985382), + ('to', 0.013058208312484141)] +``` + +As we can see, the output includes some of the seed words that we assigned. However, if a word is not found to be important in a topic than we can still multiply its importance but it will remain relatively low. This is a great feature as it allows you to improve their importance with less risk of making words important in topics that really should not be. + +A benefit of this method is that this often influences all other representation methods, like KeyBERTInspired and OpenAI. The reason for this is that each representation model uses the words generated by the `ClassTfidfTransformer` as candidate words to be further optimized. In many cases, words like *"TNM"* might not end up in the candidate words. By increasing their importance, they are more likely to end up as candidate words in representation models. + +Another benefit of using this method is that it artificially increases the interpretability of topics. Sure, some words might be more important than others but there might not mean something to a domain expert. For them, certain words, like *"TNM"* are highly descriptive and that is something difficult to capture using any method (embedding model, large language model, etc.). + +Moreover, these `seed_words` can be defined together with the domain expert as they can decide what type of words are generally important and might need a nudge from you the algorithmic developer. diff --git a/BERTopic/docs/getting_started/semisupervised/semisupervised.md b/BERTopic/docs/getting_started/semisupervised/semisupervised.md new file mode 100644 index 0000000000000000000000000000000000000000..ece4d3a1333ecac174d8f98cd5d0e7a09e8e5504 --- /dev/null +++ b/BERTopic/docs/getting_started/semisupervised/semisupervised.md @@ -0,0 +1,88 @@ +In BERTopic, you have several options to nudge the creation of topics toward certain pre-specified topics.

As a little bonus, we can use `bertopic.representation.MaximalMarginalRelevance` in BERTopic to +diversify words in each topic such that we limit the number of duplicate words we find in each topic. +This is done using an algorithm called Maximal Marginal Relevance which compares word embeddings +with the topic embedding. + +We do this by specifying a value between 0 and 1, with 0 being not at all diverse and 1 being completely diverse: + +```python +from bertopic import BERTopic +from bertopic.representation import MaximalMarginalRelevance + +representation_model = MaximalMarginalRelevance(diversity=0.2) +topic_model = BERTopic(representation_model=representation_model) +``` + +Since MMR is using word embeddings to diversify the topic representations, it is necessary to pass the embedding model to BERTopic if you are using pre-computed embeddings: + +```python +from bertopic import BERTopic +from bertopic.representation import MaximalMarginalRelevance +from sentence_transformers import SentenceTransformer + +sentence_model = SentenceTransformer("all-MiniLM-L6-v2") +embeddings = sentence_model.encode(docs, show_progress_bar=False) +representation_model = MaximalMarginalRelevance(diversity=0.2) +topic_model = BERTopic(embedding_model=sentence_model, representation_model=representation_model) +``` + + +## **Topic-term matrix** +Although BERTopic focuses on clustering our documents, the end result does contain a topic-term matrix. +This topic-term matrix is calculated using c-TF-IDF, a TF-IDF procedure optimized for class-based analyses. + +To extract the topic-term matrix (or c-TF-IDF matrix) with the corresponding words, we can simply do the following: + +```python +topic_term_matrix = topic_model.c_tf_idf_ +words = topic_model.vectorizer_model.get_feature_names() +``` + + +## **Pre-compute embeddings** +Typically, we want to iterate fast over different versions of our BERTopic model whilst we are trying to optimize it to a specific use case. To speed up this process, we can pre-compute the embeddings, save them, +and pass them to BERTopic so it does not need to calculate the embeddings each time: + +```python +from sklearn.datasets import fetch_20newsgroups +from sentence_transformers import SentenceTransformer + +# Prepare embeddings +docs = fetch_20newsgroups(subset='all', remove=('headers', 'footers', 'quotes'))['data'] +sentence_model = SentenceTransformer("all-MiniLM-L6-v2") +embeddings = sentence_model.encode(docs, show_progress_bar=False) + +# Train our topic model using our pre-trained sentence-transformers embeddings +topic_model = BERTopic() +topics, probs = topic_model.fit_transform(docs, embeddings) +``` + +## **Speed up UMAP** +At times, UMAP may take a while to fit on the embeddings that you have. This often happens when you have +the embeddings millions of documents that you want to reduce in dimensionality. There is a trick that +can speed up this process somewhat: Initializing UMAP with rescaled PCA embeddings. + +Without going in too much detail (look [here](https://github.com/lmcinnes/umap/issues/771#issuecomment-931886015) for more information), you can reduce the embeddings using PCA +and use that as a starting point. This can speed up the dimensionality reduction a bit: + + +```python +import numpy as np +from umap import UMAP +from bertopic import BERTopic +from sklearn.decomposition import PCA + + +def rescale(x, inplace=False): + """ Rescale an embedding so optimization will not have convergence issues. + """ + if not inplace: + x = np.array(x, copy=True) + + x /= np.std(x[:, 0]) * 10000 + + return x + + +# Initialize and rescale PCA embeddings +pca_embeddings = rescale(PCA(n_components=5).fit_transform(embeddings)) + +# Start UMAP from PCA embeddings +umap_model = UMAP( + n_neighbors=15, + n_components=5, + min_dist=0.0, + metric="cosine", + init=pca_embeddings, +) + +# Pass the model to BERTopic: +topic_model = BERTopic(umap_model=umap_model) +``` + +## **GPU acceleration** + +You can use [cuML](https://rapids.ai/start.html#rapids-release-selector) to speed up both +UMAP and HDBSCAN through GPU acceleration: + +```python +from bertopic import BERTopic +from cuml.cluster import HDBSCAN +from cuml.manifold import UMAP + +# Create instances of GPU-accelerated UMAP and HDBSCAN +umap_model = UMAP(n_components=5, n_neighbors=15, min_dist=0.0) +hdbscan_model = HDBSCAN(min_samples=10, gen_min_span_tree=True, prediction_data=True) + +# Pass the above models to be used in BERTopic +topic_model = BERTopic(umap_model=umap_model, hdbscan_model=hdbscan_model) +topics, probs = topic_model.fit_transform(docs) +``` + +Depending on the embeddings you are using, you might want to normalize them first in order to +force a cosine-related distance metric in UMAP: + +```python +from cuml.preprocessing import normalize +embeddings = normalize(embeddings) +``` + +!!! note + As of the v0.13 release, it is not yet possible to calculate the topic-document probability matrix for unseen data (i.e., `.transform`) using cuML's HDBSCAN. + However, it is still possible to calculate the topic-document probability matrix for the data on which the model was trained (i.e., `.fit` and `.fit_transform`). + +!!! note + If you want to install cuML together with BERTopic using Google Colab, you can run the following code: + + ```bash + !pip install bertopic + !pip install cudf-cu11 dask-cudf-cu11 --extra-index-url=https://pypi.nvidia.com + !pip install cuml-cu11 --extra-index-url=https://pypi.nvidia.com + !pip install cugraph-cu11 --extra-index-url=https://pypi.nvidia.com + !pip install --upgrade cupy-cuda11x -f https://pip.cupy.dev/aarch64 + ``` + + +## **Lightweight installation** + +The default embedding model in BERTopic is one of the amazing sentence-transformers models, namely `"all-MiniLM-L6-v2"`. Although this model performs well out of the box, it typically needs a GPU to transform the documents into embeddings in a reasonable time. Moreover, the installation requires `pytorch` which often results in a rather large environment, memory-wise. + +Fortunately, it is possible to install BERTopic without `sentence-transformers` and use it as a lightweight solution instead. The installation can be done as follows: + +```bash +pip install --no-deps bertopic +pip install --upgrade numpy hdbscan umap-learn pandas scikit-learn tqdm plotly pyyaml +``` + +Then, we can use BERTopic without `sentence-transformers` as follows using a CPU-based embedding technique: + +```python +from sklearn.pipeline import make_pipeline +from sklearn.decomposition import TruncatedSVD +from sklearn.feature_extraction.text import TfidfVectorizer + +pipe = make_pipeline( + TfidfVectorizer(), + TruncatedSVD(100) +) + +topic_model = BERTopic(embedding_model=pipe) +``` + +As a result, the entire package and resulting model can be run quickly on the CPU and no GPU is necessary! + + +## **WordCloud** +To minimize the number of dependencies in BERTopic, it is not possible to generate wordclouds out-of-the-box. However, +there is a minimal script that you can use to generate wordclouds in BERTopic. First, you will need to install +the [wordcloud](https://github.com/amueller/word_cloud) package with `pip install wordcloud`. Then, run the following code +to generate the wordcloud for a specific topic: + +```python +from wordcloud import WordCloud +import matplotlib.pyplot as plt + +def create_wordcloud(model, topic): + text = {word: value for word, value in model.get_topic(topic)} + wc = WordCloud(background_color="white", max_words=1000) + wc.generate_from_frequencies(text) + plt.imshow(wc, interpolation="bilinear") + plt.axis("off") + plt.show() + +# Show wordcloud +create_wordcloud(topic_model, topic=1) +``` + +![](wordcloud.jpg) + + +!!! tip Tip + To increase the number of words shown in the wordcloud, you can increase the `top_n_words` + parameter when instantiating BERTopic. You can also increase the number of words in a topic + after training the model using `.update_topics()`. + + +## **Finding similar topics between models** + +Whenever you have trained separate BERTopic models on different datasets, it might +be worthful to find the similarities among these models. Is there overlap between +topics in model A and topic in model B? In other words, can we find topics in model A that are similar to those in model B? + +We can compare the topic representations of several models in two ways. First, by comparing the topic embeddings that are created when using the same embedding model across both fitted BERTopic instances. Second, we can compare the c-TF-IDF representations instead assuming we have fixed the vocabulary in both instances. + +This example will go into the former, using the same embedding model across two BERTopic instances. To do this comparison, let's first create an example where I trained two models, one on an English dataset and one on a Dutch dataset: + +```python +from datasets import load_dataset +from bertopic import BERTopic +from sentence_transformers import SentenceTransformer +from bertopic import BERTopic +from umap import UMAP + +# The same embedding model needs to be used for both topic models +# and since we are dealing with multiple languages, the model needs to be multi-lingual +sentence_model = SentenceTransformer("paraphrase-multilingual-MiniLM-L12-v2") + +# To make this example reproducible +umap_model = UMAP(n_neighbors=15, n_components=5, + min_dist=0.0, metric='cosine', random_state=42) + +# English +en_dataset = load_dataset("stsb_multi_mt", name="en", split="train").to_pandas().sentence1.tolist() +en_model = BERTopic(embedding_model=sentence_model, umap_model=umap_model) +en_model.fit(en_dataset) + +# Dutch +nl_dataset = load_dataset("stsb_multi_mt", name="nl", split="train").to_pandas().sentence1.tolist() +nl_model = BERTopic(embedding_model=sentence_model, umap_model=umap_model) +nl_model.fit(nl_dataset) +``` + +In the code above, there is one important thing to note and that is the `sentence_model`. This model needs to be exactly the same in all BERTopic models, otherwise, it is not possible to compare topic models. + +Next, we can calculate the similarity between topics in the English topic model `en_model` and the Dutch model `nl_model`. To do so, we can simply calculate the cosine similarity between the `topic_embedding` of both models: + +```python +from sklearn.metrics.pairwise import cosine_similarity +sim_matrix = cosine_similarity(en_model.topic_embeddings_, nl_model.topic_embeddings_) +``` + +Now that we know which topics are similar to each other, we can extract the most similar topics. Let's say that we have topic 10 in the `en_model` which represents a topic related to trains: + +```python +>>> topic = 10 +>>> en_model.get_topic(topic) +[('train', 0.2588080580844999), + ('tracks', 0.1392140438801078), + ('station', 0.12126454635946024), + ('passenger', 0.058057876475695866), + ('engine', 0.05123717127783682), + ('railroad', 0.048142847325312044), + ('waiting', 0.04098973702226946), + ('track', 0.03978248702913929), + ('subway', 0.03834661195748458), + ('steam', 0.03834661195748458)] +``` + +To find the matching topic, we extract the most similar topic in the `sim_matrix`: + +```python +>>> most_similar_topic = np.argmax(sim_matrix[topic + 1])-1 +>>> nl_model.get_topic(most_similar_topic) +[('trein', 0.24186603209316418), + ('spoor', 0.1338118418551581), + ('sporen', 0.07683661859111401), + ('station', 0.056990389779394225), + ('stoommachine', 0.04905829711711234), + ('zilveren', 0.04083879598477808), + ('treinen', 0.03534099197032758), + ('treinsporen', 0.03534099197032758), + ('staat', 0.03481332997324445), + ('zwarte', 0.03179591746822408)] +``` + +It seems to be working as, for example, `trein` is a translation of `train` and `sporen` a translation of `tracks`! You can do this for every single topic to find out which topic in the `en_model` might belong to a model in the `nl_model`. + +## **Multimodal data** +[Concept](https://github.com/MaartenGr/Concept) is a variation +of BERTopic for multimodal data, such as images with captions. Although we can use that +package for multimodal data, we can perform a small trick with BERTopic to have a similar feature. + +BERTopic is a relatively modular approach that attempts to isolate steps from one another. This means, +for example, that you can use k-Means instead of HDBSCAN or PCA instead of UMAP as it does not make +any assumptions with respect to the nature of the clustering. + +Similarly, you can pass pre-calculated embeddings to BERTopic that represent the documents that you have. +However, it does not make any assumption with respect to the relationship between those embeddings and +the documents. This means that we could pass any metadata to BERTopic to cluster on instead of document +embeddings. In this example, we can separate our embeddings from our documents so that the embeddings +are generated from images instead of their corresponding images. Thus, we will cluster image embeddings but +create the topic representation from the related captions. + +In this example, we first need to fetch our data, namely the Flickr 8k dataset that contains images +with captions: + +```python +import os +import glob +import zipfile +import numpy as np +import pandas as pd +from tqdm import tqdm +from PIL import Image +from sentence_transformers import SentenceTransformer, util + +# Flickr 8k images +img_folder = 'photos/' +caps_folder = 'captions/' +if not os.path.exists(img_folder) or len(os.listdir(img_folder)) == 0: + os.makedirs(img_folder, exist_ok=True) + + if not os.path.exists('Flickr8k_Dataset.zip'): #Download dataset if does not exist + util.http_get('https://github.com/jbrownlee/Datasets/releases/download/Flickr8k/Flickr8k_Dataset.zip', 'Flickr8k_Dataset.zip') + util.http_get('https://github.com/jbrownlee/Datasets/releases/download/Flickr8k/Flickr8k_text.zip', 'Flickr8k_text.zip') + + for folder, file in [(img_folder, 'Flickr8k_Dataset.zip'), (caps_folder, 'Flickr8k_text.zip')]: + with zipfile.ZipFile(file, 'r') as zf: + for member in tqdm(zf.infolist(), desc='Extracting'): + zf.extract(member, folder) +images = list(glob.glob('photos/Flicker8k_Dataset/*.jpg')) + +# Prepare dataframe +captions = pd.read_csv("captions/Flickr8k.lemma.token.txt",sep='\t',names=["img_id","img_caption"]) +captions.img_id = captions.apply(lambda row: "photos/Flicker8k_Dataset/" + row.img_id.split(".jpg")[0] + ".jpg", 1) +captions = captions.groupby(["img_id"])["img_caption"].apply(','.join).reset_index() +captions = pd.merge(captions, pd.Series(images, name="img_id"), on="img_id") + +# Extract images together with their documents/captions +images = captions.img_id.to_list() +docs = captions.img_caption.to_list() +``` + +Now that we have our images and captions, we need to generate our image embeddings: + +```python +model = SentenceTransformer('clip-ViT-B-32') + +# Prepare images +batch_size = 32 +nr_iterations = int(np.ceil(len(images) / batch_size)) + +# Embed images per batch +embeddings = [] +for i in tqdm(range(nr_iterations)): + start_index = i * batch_size + end_index = (i * batch_size) + batch_size + + images_to_embed = [Image.open(filepath) for filepath in images[start_index:end_index]] + img_emb = model.encode(images_to_embed, show_progress_bar=False) + embeddings.extend(img_emb.tolist()) + + # Close images + for image in images_to_embed: + image.close() +embeddings = np.array(embeddings) +``` + +Finally, we can fit BERTopic the way we are used to, with documents and embeddings: + +```python +from bertopic import BERTopic +from sklearn.cluster import KMeans +from sklearn.feature_extraction.text import CountVectorizer + +vectorizer_model = CountVectorizer(stop_words="english") +topic_model = BERTopic(vectorizer_model=vectorizer_model) +topics, probs = topic_model.fit_transform(docs, embeddings) +captions["Topic"] = topics +``` + +After fitting our model, let's inspect a topic about skateboarders: + +```python +>>> topic_model.get_topic(2) +[('skateboard', 0.09592033177340711), + ('skateboarder', 0.07792520092546491), + ('trick', 0.07481578896400298), + ('ramp', 0.056952605147927216), + ('skate', 0.03745127816149923), + ('perform', 0.036546213623432654), + ('bicycle', 0.03453483070441857), + ('bike', 0.033233021253898994), + ('jump', 0.026709362981948037), + ('air', 0.025422798170830936)] +``` + +Based on the above output, we can take an image to see if the representation makes sense: + +```python +image = captions.loc[captions.Topic == 2, "img_id"].values.tolist()[0] +Image.open(image) +``` + +![](skateboarders.jpg) + +## **KeyBERT** & **BERTopic** + +Although BERTopic focuses on topic extraction methods that does not assume specific structures for the generated clusters, it is possible to do this on a more local level. More specifically, we can use KeyBERT to generate a number of keywords for each document and then build a vocabulary on top of that as the input for BERTopic. This way, we can select words that we know have meaning to a topic, without focusing on the centroid of that cluster. This also allows more frequent words to pop-up regardless of the structure and density of a cluster. + +To do this, we first need to run [KeyBERT](https://github.com/MaartenGr/KeyBERT) on our data and create our vocabulary: + +```python +from sklearn.datasets import fetch_20newsgroups +from keybert import KeyBERT + +# Prepare documents +docs = fetch_20newsgroups(subset='all', remove=('headers', 'footers', 'quotes'))['data'] + +# Extract keywords +kw_model = KeyBERT() +keywords = kw_model.extract_keywords(docs) + +# Create our vocabulary +vocabulary = [k[0] for keyword in keywords for k in keyword] +vocabulary = list(set(vocabulary)) +``` + +Then, we pass our `vocabulary` to BERTopic and train the model: + +```python +from bertopic import BERTopic +from sklearn.feature_extraction.text import CountVectorizer + +vectorizer_model= CountVectorizer(vocabulary=vocabulary) +topic_model = BERTopic(vectorizer_model=vectorizer_model) +topics, probs = topic_model.fit_transform(docs) +``` diff --git a/BERTopic/docs/getting_started/tips_and_tricks/wordcloud.jpg b/BERTopic/docs/getting_started/tips_and_tricks/wordcloud.jpg new file mode 100644 index 0000000000000000000000000000000000000000..04db575030ab0b934a3bf4f92973fefe6b4361a4 Binary files /dev/null and b/BERTopic/docs/getting_started/tips_and_tricks/wordcloud.jpg differ diff --git a/BERTopic/docs/getting_started/topicreduction/topicreduction.md b/BERTopic/docs/getting_started/topicreduction/topicreduction.md new file mode 100644 index 0000000000000000000000000000000000000000..d9762d373a90349c98213d9d14df01f713a17265 --- /dev/null +++ b/BERTopic/docs/getting_started/topicreduction/topicreduction.md @@ -0,0 +1,67 @@ +BERTopic uses HDBSCAN for clustering the data and it cannot specify the number of clusters you would want.

These outliers prevent topics from being merged if no other topics are similar. + +To use this option, we simply set `nr_topics` to `"auto"`: + +```python +from bertopic import BERTopic +topic_model = BERTopic(nr_topics="auto") +``` + +### **Topic Reduction after Training** +Finally, we can also reduce the number of topics after having trained a BERTopic model.

To truly understand which labels are most suited, going into some of the documents in topics is especially helpful. + +Although we can go through every single topic ourselves and try to label them, we can start by creating an overview of labels that have the length and number of words that we are looking for. To do so, we can generate our list of topic labels with `.generate_topic_labels` and define the number of words, the separator, word length, etc: + +```python +topic_labels = topic_model.generate_topic_labels(nr_words=3, + topic_prefix=False, + word_length=10, + separator=", ") +``` + +!!! Tip + If you created [**multiple topic representations**](https://maartengr.github.io/BERTopic/getting_started/multiaspect/multiaspect.html) or aspects, you can choose one of these aspects with `aspect="Aspect1"` or whatever you named the aspect. + +In the above example, `1_space_nasa_orbit` would turn into `space, nasa, orbit` since we selected 3 words, no topic prefix, and the `, ` separator. We can then either change our `topic_labels` to whatever we want or directly pass them to `.set_topic_labels` so that they can be used across most visualization functions: + +```python +topic_model.set_topic_labels(topic_labels) +``` + +It is also possible to only change a few topic labels at a time by passing a dictionary +where the key represents the *topic ID* and the value is the *topic label*: + +```python +topic_model.set_topic_labels({1: "Space Travel", 7: "Religion"}) +``` + +Then, to make use of those custom topic labels across visualizations, such as `.visualize_hierarchy()`, +we can use the `custom_labels=True` parameter that is found in most visualizations. + +```python +fig = topic_model.visualize_barchart(custom_labels=True) +``` + +#### Optimize labels +The great advantage of passing custom labels to BERTopic is that when more accurate zero-shot are released, +we can simply use those on top of BERTopic to further fine-tune the labeling. For example, let's say you +have a set of potential topic labels that you want to use instead of the ones generated by BERTopic.

These methods allow you to understand how a topic is represented across different times. +For example, in 1995 people may talk differently about environmental awareness than those in 2015. Although the +topic itself remains the same, environmental awareness, the exact representation of that topic might differ. + +BERTopic allows for DTM by calculating the topic representation at each timestep without the need to +run the entire model several times. To do this, we first need to fit BERTopic as if there were no temporal +aspect in the data. Thus, a general topic model will be created. We use the global representation as to the main topics that can be found at, most likely, different timesteps. For each topic and timestep, we calculate the c-TF-IDF representation. This will result in a specific topic representation at each timestep without the need to create clusters from embeddings as they were already created. + +
+
+--8<-- "docs/getting_started/topicsovertime/topicsovertime.svg" +
+
+ +Next, there are two main ways to further fine-tune these specific topic representations, +namely **globally** and **evolutionary**. + +A topic representation at timestep *t* can be fine-tuned **globally** by averaging its c-TF-IDF representation with that of the global representation. This allows each topic representation to move slightly towards the global representation whilst still keeping some of its specific words. + +A topic representation at timestep *t* can be fine-tuned **evolutionary** by averaging its c-TF-IDF representation with that of the c-TF-IDF representation at timestep *t-1*. This is done for each topic representation allowing for the representations to evolve over time. + +Both fine-tuning methods are set to `True` as a default and allow for interesting representations to be created. + +## **Example** +To demonstrate DTM in BERTopic, we first need to prepare our data. A good example of where DTM is useful is topic +modeling on Twitter data. We can analyze how certain people have talked about certain topics in the years +they have been on Twitter. Due to the controversial nature of his tweets, we are going to be using all +tweets by Donald Trump. + +First, we need to load the data and do some very basic cleaning. For example, I am not interested in his +re-tweets for this use-case: + +```python +import re +import pandas as pd + +# Prepare data +trump = pd.read_csv('https://drive.google.com/uc?export=download&id=1xRKHaP-QwACMydlDnyFPEaFdtskJuBa6') +trump.text = trump.apply(lambda row: re.sub(r"http\S+", "", row.text).lower(), 1) +trump.text = trump.apply(lambda row: " ".join(filter(lambda x:x[0]!="@", row.text.split())), 1) +trump.text = trump.apply(lambda row: " ".join(re.sub("[^a-zA-Z]+", " ", row.text).split()), 1) +trump = trump.loc[(trump.isRetweet == "f") & (trump.text != ""), :] +timestamps = trump.date.to_list() +tweets = trump.text.to_list() +``` + +Then, we need to extract the global topic representations by simply creating and training a BERTopic model: + +```python +from bertopic import BERTopic + +topic_model = BERTopic(verbose=True) +topics, probs = topic_model.fit_transform(tweets) +``` + +From these topics, we are going to generate the topic representations at each timestamp for each topic. We do this +by simply calling `topics_over_time` and passing the tweets, the corresponding timestamps, and the related topics: + +```python +topics_over_time = topic_model.topics_over_time(tweets, timestamps, nr_bins=20) +``` + +And that is it! Aside from what you always need for BERTopic, you now only need to add `timestamps` +to quickly calculate the topics over time. + +## **Parameters** +There are a few parameters that are of interest which will be discussed below. + +### **Tuning** +Both `global_tuning` and `evolutionary_tuning` are set to True as a default, but can easily be changed. Perhaps +you do not want the representations to be influenced by the global representation and merely see how they +evolved over time: + +```python +topics_over_time = topic_model.topics_over_time(tweets, timestamps, + global_tuning=True, evolution_tuning=True, nr_bins=20) +``` + +### **Bins** +If you have more than 100 unique timestamps, then there will be topic representations created for each of those +timestamps which can negatively affect the topic representations. It is advised to keep the number of unique +timestamps below 50. To do this, you can simply set the number of bins that are created when calculating the +topic representations. The timestamps will be taken and put into equal-sized bins: + +```python +topics_over_time = topic_model.topics_over_time(tweets, timestamps, nr_bins=20) +``` + +### **Datetime format** +If you are passing strings (dates) instead of integers, then BERTopic will try to automatically detect +which datetime format your strings have. Unfortunately, this will not always work if they are in an unexpected format. +We can use `datetime_format` to pass the format the timestamps have: + +```python +topics_over_time = topic_model.topics_over_time(tweets, timestamps, datetime_format="%b%M", nr_bins=20) +``` + +## **Visualization** +To me, DTM becomes truly interesting when you have a good way of visualizing how topics have changed over time. +A nice way of doing so is by leveraging the interactive abilities of Plotly. Plotly allows us to show the frequency +of topics over time whilst giving the option of hovering over the points to show the time-specific topic representations. +Simply call `visualize_topics_over_time` with the newly created topics over time: + +```python +topic_model.visualize_topics_over_time(topics_over_time, top_n_topics=20) +``` + +I used `top_n_topics` to only show the top 20 most frequent topics.

However, I am quite sure we do much better without having +to re-train our model. Next, we will go through common parameters in `CountVectorizer` and focus on the effects that they might have. As a baseline, we will be comparing +them to the topic representation above. + +### **Parameters** + +There are several basic parameters in the CountVectorizer that we can use to improve upon the quality of the resulting topic representations. + +#### ngram_range + +The `ngram_range` parameter allows us to decide how many tokens each entity is in a topic representation. For example, we have words like +`game` and `team` with a length of 1 in a topic but it would also make sense to have words like `hockey league` with a length of 2. To allow for these words to be generated, +we can set the `ngram_range` parameter: + + +```python +from sklearn.feature_extraction.text import CountVectorizer +vectorizer_model = CountVectorizer(ngram_range=(1, 3), stop_words="english") +topic_model.update_topics(docs, vectorizer_model=vectorizer_model) +``` + +As you might have noticed, I also added `stop_words="english"`. This is necessary as longer words tend to have many stop words and removing them allows +for nicer topic representations: + +```python +>>> topic_model.get_topic_info()[1:11] + Topic Count Name +1 0 1822 0_game_team_games_players +2 1 580 1_key_clipper_chip_encryption +3 2 532 2_hello ites_forget hello_ites 15_huh hi +4 3 493 3_israel_israeli_jews_arab +5 4 453 4_card_monitor_video_drivers +6 5 438 5_post_jim_context_forged +7 6 314 6_car_cars_engine_ford +8 7 279 7_health_newsgroup_cancer_1993 +9 8 218 8_fbi_koresh_gas_compound +10 9 174 9_amp_audio_condition_asking +``` + +Although they look very similar, if we zoom in on topic 8, we can see longer words in our representation: + +```python +>>> topic_model.get_topic(8) +[('fbi', 0.019637149205975653), + ('koresh', 0.019054514637064403), + ('gas', 0.014156057632897179), + ('compound', 0.012381224868591681), + ('batf', 0.010349992314076047), + ('children', 0.009336408916322387), + ('tear gas', 0.008941747802855279), + ('tear', 0.008446786597564537), + ('davidians', 0.007911119583253022), + ('started', 0.007398687505638955)] +``` + +`tear` and `gas` have now been combined into a single representation. This helps us understand what those individual words might have been representing. + +#### stop_words + +In some of the topics, we can see stop words appearing like `he` or `the`. +Stop words are something we typically want to prevent in our topic representations as they do not give additional information to the topic. +To prevent those stop words, we can use the `stop_words` parameter in the `CountVectorizer` to remove them from the representations: + +```python +from sklearn.feature_extraction.text import CountVectorizer +vectorizer_model = CountVectorizer(stop_words="english") +topic_model.update_topics(docs, vectorizer_model=vectorizer_model) +``` + +After running the above, we get the following output: + +```python +>>> topic_model.get_topic_info()[1:11] + Topic Count Name +1 0 1822 0_game_team_games_players +2 1 580 1_key_clipper_chip_encryption +3 2 532 2_ites_cheek_hello_hi +4 3 493 3_israel_israeli_jews_arab +5 4 453 4_monitor_card_video_vga +6 5 438 5_post_jim_context_forged +7 6 314 6_car_cars_engine_ford +8 7 279 7_health_newsgroup_cancer_tobacco +9 8 218 8_fbi_koresh_gas_compound +10 9 174 9_amp_audio_condition_stereo +``` + +As you can see, the topic representations already look much better! Stop words are removed and the representations are more interpretable. +We can also pass in a list of stop words if you have multiple languages to take into account. + + +#### min_df + +One important parameter to keep in mind is the `min_df`. This is typically an integer representing how frequent a word must be before +being added to our representation. You can imagine that if we have a million documents and a certain word only appears a single time across all of them, then +it would be highly unlikely to be representative of a topic. Typically, the `c-TF-IDF` calculation removes that word from the topic representation but when +you have millions of documents, that will also lead to a very large topic-term matrix. To prevent a huge vocabulary, we can set the `min_df` to only accept +words that have a minimum frequency. + +When you have millions of documents or error issues, I would advise increasing the value of `min_df` as long as the topic representations might sense: + +```python +from sklearn.feature_extraction.text import CountVectorizer +vectorizer_model = CountVectorizer(min_df=10) +topic_model.update_topics(docs, vectorizer_model=vectorizer_model) +``` + +With the following topic representation: + +```python +>>> topic_model.get_topic_info()[1:11] + Topic Count Name +1 0 1822 0_game_team_games_he +2 1 580 1_key_clipper_chip_encryption +3 2 532 2_hello_hi_yep_huh +4 3 493 3_israel_jews_jewish_peace +5 4 453 4_card_monitor_video_drivers +6 5 438 5_you_your_post_jim +7 6 314 6_car_cars_engine_ford +8 7 279 7_health_newsgroup_cancer_1993 +9 8 218 8_fbi_koresh_fire_gas +10 9 174 9_audio_condition_stereo_asking +``` + +As you can see, the output is nearly the same which is what we would like to achieve. All words that appear less than 10 times are now removed +from our topic-term matrix (i.e., `c-TF-IDF` matrix) which drastically lowers the matrix in size. + + +#### max_features + +A parameter similar to `min_df` is `max_features` which allows you to select the top n most frequent words to be used in the topic representation. +Setting this, for example, to `10_000` creates a topic-term matrix with `10_000` terms. This helps you control the size of the topic-term matrix +directly without having to fiddle around with the `min_df` parameter: + +```python +from sklearn.feature_extraction.text import CountVectorizer +vectorizer_model = CountVectorizer(max_features=10_000) +topic_model.update_topics(docs, vectorizer_model=vectorizer_model) +``` + +With the following representation: + +```python +>>> topic_model.get_topic_info()[1:11] +Topic Count Name +1 0 1822 0_game_team_games_he +2 1 580 1_key_clipper_chip_encryption +3 2 532 2_hello_hi_yep_huh +4 3 493 3_israel_israeli_jews_arab +5 4 453 4_card_monitor_video_drivers +6 5 438 5_you_your_post_jim +7 6 314 6_car_cars_engine_ford +8 7 279 7_health_newsgroup_cancer_1993 +9 8 218 8_fbi_koresh_fire_gas +10 9 174 9_amp_audio_condition_asking +``` + +As with `min_df`, we would like the topic representations to be very similar. + +#### tokenizer + +The default tokenizer in the CountVectorizer works well for western languages but fails to tokenize some non-western languages, like Chinese. +Fortunately, we can use the `tokenizer` variable in the CountVectorizer to use [`jieba`](https://github.com/fxsjy/jieba), which is a package +for Chinese text segmentation. Using it is straightforward: + +```python +from sklearn.feature_extraction.text import CountVectorizer +import jieba + +def tokenize_zh(text): + words = jieba.lcut(text) + return words + +vectorizer = CountVectorizer(tokenizer=tokenize_zh) +``` + +Then, we can simply pass the vectorizer to update our topic representations: + +```python +topic_model.update_topics(docs, vectorizer_model=vectorizer_model) +``` + + +## **OnlineCountVectorizer** + +When using the online/incremental variant of BERTopic, we need a `CountVectorizer` than can incrementally update its representation. For that purpose, `OnlineCountVectorizer` was created that not only updates out-of-vocabulary words but also implements decay and cleaning functions to prevent the sparse bag-of-words matrix to become too large. It is a class that can be found in `bertopic.vectorizers` which extends `sklearn.feature_extraction.text.CountVectorizer`. In other words, you can use the exact same parameter in `OnlineCountVectorizer` as found in Scikit-Learn's `CountVectorizer`. We can use it as follows: + +```python +from bertopic import BERTopic +from bertopic.vectorizers import OnlineCountVectorizer + +# Train BERTopic with a custom OnlineCountVectorizer +vectorizer_model = OnlineCountVectorizer() +topic_model = BERTopic(vectorizer_model=vectorizer_model) +``` + +### **Parameters** + +Other than parameters found in `CountVectorizer`, such as `stop_words` and `ngram_range`, we can two parameters in `OnlineCountVectorizer` to adjust the way old data is processed and kept. + +#### decay + +At each iteration, we sum the bag-of-words representation of the new documents with the bag-of-words representation of all documents processed thus far. In other words, the bag-of-words matrix keeps increasing with each iteration. However, especially in a streaming setting, older documents might become less and less relevant as time goes on. Therefore, a `decay` parameter was implemented that decays the bag-of-words' frequencies at each iteration before adding the document frequencies of new documents. The `decay` parameter is a value between 0 and 1 and indicates the percentage of frequencies the previous bag-of-words matrix should be reduced to. For example, a value of `.1` will decrease the frequencies in the bag-of-words matrix by 10% at each iteration before adding the new bag-of-words matrix. This will make sure that recent data has more weight than previous iterations. + +#### delete_min_df + +In BERTopic, we might want to remove words from the topic representation that appear infrequently. The `min_df` in the `CountVectorizer` works quite well for that. However, when we have a streaming setting, the `min_df` does not work as well since a word's frequency might start below `min_df` but will end up higher than that over time. Setting that value high might not always be advised. + +As a result, the vocabulary of the resulting bag-of-words matrix can become quite large. Similarly, if we implement the `decay` parameter, then some values will decrease over time until they are below `min_df`. For these reasons, the `delete_min_df` parameter was implemented. The parameter takes positive integers and indicates, at each iteration, which words will be removed. If the value is set to 5, it will check after each iteration if the total frequency of a word is exceeded by that value. If so, the word will be removed in its entirety from the bag-of-words matrix. This helps to keep the bag-of-words matrix of a manageable size. + +!!! note + Although the `delete_min_df` parameter removes words from the bag-of-words matrix, it is not permanent. If new documents come in where those previously deleted words are used frequently, they get added back to the matrix. \ No newline at end of file diff --git a/BERTopic/docs/getting_started/vectorizers/vectorizers.svg b/BERTopic/docs/getting_started/vectorizers/vectorizers.svg new file mode 100644 index 0000000000000000000000000000000000000000..1e2d364271ef1858609a57b25fd621189d0a3cbd --- /dev/null +++ b/BERTopic/docs/getting_started/vectorizers/vectorizers.svg @@ -0,0 +1,53 @@ + + + + + + +SBERT + + + + + +UMAP + + + + + +HDBSCAN + + + + + +CountVectorizer + + + + + +Jieba + + + + + +c-TF-IDF + + + + + +Optional Fine-tuning + + + + + +POS + + + + diff --git a/BERTopic/docs/getting_started/visualization/bar_chart.html b/BERTopic/docs/getting_started/visualization/bar_chart.html new file mode 100644 index 0000000000000000000000000000000000000000..3e369e4c7741e67f84f98951c1a50a1842ed0762 --- /dev/null +++ b/BERTopic/docs/getting_started/visualization/bar_chart.html @@ -0,0 +1,7 @@ + + + +

Looking at the topics and seeing +if they make sense is an important factor in alleviating this issue. + +## **Visualize Topics** +After having trained our `BERTopic` model, we can iteratively go through hundreds of topics to get a good +understanding of the topics that were extracted. However, that takes quite some time and lacks a global representation. +Instead, we can visualize the topics that were generated in a way very similar to +[LDAvis](https://github.com/cpsievert/LDAvis). + +We embed our c-TF-IDF representation of the topics in 2D using Umap and then visualize the two dimensions using +plotly such that we can create an interactive view. + +First, we need to train our model: + +```python +from bertopic import BERTopic +from sklearn.datasets import fetch_20newsgroups + +docs = fetch_20newsgroups(subset='all', remove=('headers', 'footers', 'quotes'))['data'] +topic_model = BERTopic() +topics, probs = topic_model.fit_transform(docs) +``` + +Then, we can call `.visualize_topics` to create a 2D representation of your topics. The resulting graph is a +plotly interactive graph which can be converted to HTML: + +```python +topic_model.visualize_topics() +``` + + + +You can use the slider to select the topic which then lights up red. If you hover over a topic, then general +information is given about the topic, including the size of the topic and its corresponding words. + +## **Visualize Documents** +Using the previous method, we can visualize the topics and get insight into their relationships. However, +you might want a more fine-grained approach where we can visualize the documents inside the topics to see +if they were assigned correctly or whether they make sense. To do so, we can use the `topic_model.visualize_documents()` +function. This function recalculates the document embeddings and reduces them to 2-dimensional space for easier visualization +purposes. This process can be quite expensive, so it is advised to adhere to the following pipeline: + +```python +from sklearn.datasets import fetch_20newsgroups +from sentence_transformers import SentenceTransformer +from bertopic import BERTopic +from umap import UMAP + +# Prepare embeddings +docs = fetch_20newsgroups(subset='all', remove=('headers', 'footers', 'quotes'))['data'] +sentence_model = SentenceTransformer("all-MiniLM-L6-v2") +embeddings = sentence_model.encode(docs, show_progress_bar=False) + +# Train BERTopic +topic_model = BERTopic().fit(docs, embeddings) + +# Run the visualization with the original embeddings +topic_model.visualize_documents(docs, embeddings=embeddings) + +# Reduce dimensionality of embeddings, this step is optional but much faster to perform iteratively: +reduced_embeddings = UMAP(n_neighbors=10, n_components=2, min_dist=0.0, metric='cosine').fit_transform(embeddings) +topic_model.visualize_documents(docs, reduced_embeddings=reduced_embeddings) +``` + + + + +!!! note + The visualization above was generated with the additional parameter `hide_document_hover=True` which disables the + option to hover over the individual points and see the content of the documents. This was done for demonstration purposes + as saving all those documents in the visualization can be quite expensive and result in large files. However, + it might be interesting to set `hide_document_hover=False` in order to hover over the points and see the content of the documents. + +### **Custom Hover** + +When you visualize the documents, you might not always want to see the complete document over hover. Many documents have shorter information that might be more interesting to visualize, such as its title. To create the hover based on a documents' title instead of its content, you can simply pass a variable (`titles`) containing the title for each document: + +```python +topic_model.visualize_documents(titles, reduced_embeddings=reduced_embeddings) +``` + +## **Visualize Topic Hierarchy** +The topics that were created can be hierarchically reduced. In order to understand the potential hierarchical +structure of the topics, we can use `scipy.cluster.hierarchy` to create clusters and visualize how +they relate to one another. This might help to select an appropriate `nr_topics` when reducing the number +of topics that you have created. To visualize this hierarchy, run the following: + +```python +topic_model.visualize_hierarchy() +``` + + + +!!! note + Do note that this is not the actual procedure of `.reduce_topics()` when `nr_topics` is set to + auto since HDBSCAN is used to automatically extract topics. The visualization above closely resembles + the actual procedure of `.reduce_topics()` when any number of `nr_topics` is selected. + +### **Hierarchical labels** + +Although visualizing this hierarchy gives us information about the structure, it would be helpful to see what happens +to the topic representations when merging topics. To do so, we first need to calculate the representations of the +hierarchical topics: + + +First, we train a basic BERTopic model: + +```python +from bertopic import BERTopic +from sklearn.datasets import fetch_20newsgroups + +docs = fetch_20newsgroups(subset='all', remove=('headers', 'footers', 'quotes'))["data"] +topic_model = BERTopic(verbose=True) +topics, probs = topic_model.fit_transform(docs) +hierarchical_topics = topic_model.hierarchical_topics(docs) +``` + +To visualize these results, we simply need to pass the resulting `hierarchical_topics` to our `.visualize_hierarchy` function: + +```python +topic_model.visualize_hierarchy(hierarchical_topics=hierarchical_topics) +``` + + + +If you **hover** over the black circles, you will see the topic representation at that level of the hierarchy. These representations +help you understand the effect of merging certain topics. Some might be logical to merge whilst others might not. Moreover, +we can now see which sub-topics can be found within certain larger themes. + +### **Text-based topic tree** + +Although this gives a nice overview of the potential hierarchy, hovering over all black circles can be tiresome. Instead, we can +use `topic_model.get_topic_tree` to create a text-based representation of this hierarchy. Although the general structure is more difficult +to view, we can see better which topics could be logically merged: + +```python +>>> tree = topic_model.get_topic_tree(hierarchical_topics) +>>> print(tree) +. +└─atheists_atheism_god_moral_atheist + β”œβ”€atheists_atheism_god_atheist_argument + β”‚ β”œβ”€β– β”€β”€atheists_atheism_god_atheist_argument ── Topic: 21 + β”‚ └─■──br_god_exist_genetic_existence ── Topic: 124 + └─■──moral_morality_objective_immoral_morals ── Topic: 29 +``` + +

+ +## **Visualize Hierarchical Documents** +We can extend the previous method by calculating the topic representation at different levels of the hierarchy and +plotting them on a 2D plane. To do so, we first need to calculate the hierarchical topics: + +```python +from sklearn.datasets import fetch_20newsgroups +from sentence_transformers import SentenceTransformer +from bertopic import BERTopic +from umap import UMAP + +# Prepare embeddings +docs = fetch_20newsgroups(subset='all', remove=('headers', 'footers', 'quotes'))['data'] +sentence_model = SentenceTransformer("all-MiniLM-L6-v2") +embeddings = sentence_model.encode(docs, show_progress_bar=False) + +# Train BERTopic and extract hierarchical topics +topic_model = BERTopic().fit(docs, embeddings) +hierarchical_topics = topic_model.hierarchical_topics(docs) +``` +Then, we can visualize the hierarchical documents by either supplying it with our embeddings or by +reducing their dimensionality ourselves: + +```python +# Run the visualization with the original embeddings +topic_model.visualize_hierarchical_documents(docs, hierarchical_topics, embeddings=embeddings) + +# Reduce dimensionality of embeddings, this step is optional but much faster to perform iteratively: +reduced_embeddings = UMAP(n_neighbors=10, n_components=2, min_dist=0.0, metric='cosine').fit_transform(embeddings) +topic_model.visualize_hierarchical_documents(docs, hierarchical_topics, reduced_embeddings=reduced_embeddings) +``` + + + +!!! note + The visualization above was generated with the additional parameter `hide_document_hover=True` which disables the + option to hover over the individual points and see the content of the documents. This makes the resulting visualization + smaller and fit into your RAM. However, it might be interesting to set `hide_document_hover=False` to hover + over the points and see the content of the documents. + +## **Visualize Terms** +We can visualize the selected terms for a few topics by creating bar charts out of the c-TF-IDF scores +for each topic representation. Insights can be gained from the relative c-TF-IDF scores between and within +topics. Moreover, you can easily compare topic representations to each other. +To visualize this hierarchy, run the following: + +```python +topic_model.visualize_barchart() +``` + + + + +## **Visualize Topic Similarity** +Having generated topic embeddings, through both c-TF-IDF and embeddings, we can create a similarity +matrix by simply applying cosine similarities through those topic embeddings. The result will be a +matrix indicating how similar certain topics are to each other. +To visualize the heatmap, run the following: + +```python +topic_model.visualize_heatmap() +``` + + + + +!!! note + You can set `n_clusters` in `visualize_heatmap` to order the topics by their similarity. + This will result in blocks being formed in the heatmap indicating which clusters of topics are + similar to each other. This step is very much recommended as it will make reading the heatmap easier. + + +## **Visualize Term Score Decline** +Topics are represented by a number of words starting with the best representative word. +Each word is represented by a c-TF-IDF score. The higher the score, the more representative a word +to the topic is. Since the topic words are sorted by their c-TF-IDF score, the scores slowly decline +with each word that is added. At some point adding words to the topic representation only marginally +increases the total c-TF-IDF score and would not be beneficial for its representation. + +To visualize this effect, we can plot the c-TF-IDF scores for each topic by the term rank of each word. +In other words, the position of the words (term rank), where the words with +the highest c-TF-IDF score will have a rank of 1, will be put on the x-axis. Whereas the y-axis +will be populated by the c-TF-IDF scores. The result is a visualization that shows you the decline +of c-TF-IDF score when adding words to the topic representation. It allows you, using the elbow method, +the select the best number of words in a topic. + +To visualize the c-TF-IDF score decline, run the following: + +```python +topic_model.visualize_term_rank() +``` + + + +To enable the log scale on the y-axis for a better view of individual topics, run the following: + +```python +topic_model.visualize_term_rank(log_scale=True) +``` + + + +This visualization was heavily inspired by the "Term Probability Decline" visualization found in an +analysis by the amazing [tmtoolkit](https://tmtoolkit.readthedocs.io/). +Reference to that specific analysis can be found +[here](https://wzbsocialsciencecenter.github.io/tm_corona/tm_analysis.html). + +## **Visualize Topics over Time** +After creating topics over time with Dynamic Topic Modeling, we can visualize these topics by +leveraging the interactive abilities of Plotly. Plotly allows us to show the frequency +of topics over time whilst giving the option of hovering over the points to show the time-specific topic representations. +Simply call `.visualize_topics_over_time` with the newly created topics over time: + + +```python +import re +import pandas as pd +from bertopic import BERTopic + +# Prepare data +trump = pd.read_csv('https://drive.google.com/uc?export=download&id=1xRKHaP-QwACMydlDnyFPEaFdtskJuBa6') +trump.text = trump.apply(lambda row: re.sub(r"http\S+", "", row.text).lower(), 1) +trump.text = trump.apply(lambda row: " ".join(filter(lambda x:x[0]!="@", row.text.split())), 1) +trump.text = trump.apply(lambda row: " ".join(re.sub("[^a-zA-Z]+", " ", row.text).split()), 1) +trump = trump.loc[(trump.isRetweet == "f") & (trump.text != ""), :] +timestamps = trump.date.to_list() +tweets = trump.text.to_list() + +# Create topics over time +model = BERTopic(verbose=True) +topics, probs = model.fit_transform(tweets) +topics_over_time = model.topics_over_time(tweets, timestamps) +``` + +Then, we visualize some interesting topics: + +```python +model.visualize_topics_over_time(topics_over_time, topics=[9, 10, 72, 83, 87, 91]) +``` + + +## **Visualize Topics per Class** +You might want to extract and visualize the topic representation per class.

When faced with many documents, you often have an idea of which topics will definitely be in there. Whether that is a result of simply knowing your data or if a domain expert is involved in defining those topics. + +This method allows you to not only find those specific topics but also create new topics for documents that would not fit with your predefined topics. +This allows for extensive flexibility as there are three scenario's to explore. + +First, both zero-shot topics and clustered topics were detected. This means that some documents would fit with the predefined topics where others would not. For the latter, new topics were found. + +Second, only zero-shot topics were detected. Here, we would not need to find additional topics since all original documents were assigned to one of the predefined topics. + +Third, no zero-shot topics were detected. This means that none of the documents would fit with the predefined topics and a regular BERTopic would be run. + +
+--8<-- "docs/getting_started/zeroshot/zeroshot.svg" +
+ +This method works as follows. First, we create a number of labels for our predefined topics and embed them using any embedding model. Then, we compare the embeddings of the documents with the predefined labels using cosine similarity. If they pass a user-defined threshold, the zero-shot topic is assigned to a document. If it does not, then that document, along with others, will be put through a regular BERTopic model. + +This creates two models. One for the zero-shot topics and one for the non-zero-shot topics. We combine these two BERTopic models to create a single model that contains both zero-shot and non-zero-shot topics. + +### **Example** +In order to use zero-shot BERTopic, we create a list of topics that we want to assign to our documents. However, +there may be several other topics that we know should be in the documents. The dataset that we use is small subset of ArXiv papers. +We know the data and believe there to be at least the following topics: *clustering*, *topic modeling*, and *large language models*. +However, we are not sure whether other topics exist and want to explore those. + +Zero-shot BERTopic needs two parameters: +* `zeroshot_topic_list` - The names of the topics to assign documents to. Making sure this is as descriptive as possible helps improve the assignment since they are based on cosine similarities between embeddings. +* `zeroshot_min_similarity` - The minimum cosine similarity needed to match a document to a document. It is a value between 0 and 1. + + +Using this feature is straightforward: + +```python +from datasets import load_dataset + +from bertopic import BERTopic +from bertopic.representation import KeyBERTInspired + +# We select a subsample of 5000 abstracts from ArXiv +dataset = load_dataset("CShorten/ML-ArXiv-Papers")["train"] +docs = dataset["abstract"][:5_000] + +# We define a number of topics that we know are in the documents +zeroshot_topic_list = ["Clustering", "Topic Modeling", "Large Language Models"] + +# We fit our model using the zero-shot topics +# and we define a minimum similarity. For each document, +# if the similarity does not exceed that value, it will be used +# for clustering instead. +topic_model = BERTopic( + embedding_model="thenlper/gte-small", + min_topic_size=15, + zeroshot_topic_list=zeroshot_topic_list, + zeroshot_min_similarity=.85, + representation_model=KeyBERTInspired() +) +topics, _ = topic_model.fit_transform(docs) +``` + +When we run `topic_model.get_topic_info()` you will see something like this: + + +
+ +The `zeroshot_min_similarity` parameter controls how many of the documents are assigned to the predefined zero-shot topics. Lower this value and you will have more documents assigned to zero-shot topics and fewer documents will be clustered. Increase this value you will have fewer documents assigned to zero-shot topics and more documents will be clustered. + +!!! Note + Setting the `zeroshot_min_similarity` parameter requires a bit of experimentation.

+ The phone call memos are written by hundreds of independent volunteers and come in various shapes, lengths, forms, and wordings - additionally to have them in multiple languages. While using BERTopic we ran a few tests to figure out if the topic modeling works. Selecting only one language with ~60K data points and a mixed language model we achieved good results. It helped identify topics within the calls and therefore show the organization what reasons there are for people calling them. We identified in a workshop a few interesting topics, which they were not aware of, for example, religious topics.

+ The identification of existing and new, arising topics is crucial for the service quality of the organization. It furthermore helps detect trends over time, which can then be reported directly to Public Health institutions, which can then come up with campaigns to inform the public and help reduce certain psychological concerns. It acts as a representative psychological health barometer of the population."

+ +#### Regional Newspaper + +!!! quote "" +

+

+ "Recently, we wanted to evaluate our overall section structure, especially our local news section. As you can imagine, local news is quite a big part of what we do in a regional newspaper. We used BERTopic on a year's worth of local news data to explore the topics in local news and define a new section structure. The results from this analysis helped to define the new section structure, which was implemented this month. "

+ +#### Zero Hunger Lab + +!!! quote "" +

+

+ "I am a PhD student at Tilburg University, at a lab called Zero Hunger Lab, where we try to use data science methods to improve food insecurity. One key issue is classifying and predicting food insecurity in food-insecure nations. The Integrated Food Security Phase Classification (IPC) system serves this purpose. The IPC categorizes food insecurity into five phases, ranging from minimal food insecurity to famine, and serves as a guide for directing humanitarian resources to the most affected regions.

+ The IPC system strives to be based on evidence, however, obtaining accurate information about food insecurity in remote regions can prove challenging. Despite the availability of weather data, data in the socio-economic domain, such as food prices and conflict, can be scarce or unreliable due to limited infrastructure and bureaucratic obstacles. These complications often result in infrequent releases of IPC classifications and projections, making it difficult to effectively respond to food insecurity in these areas.

+ One large source of daily-updated information is local news. Thus, one can build a model that classifies/predicts IPC by relying on news features obtained by NLP methods in addition to stuff like weather data. Previous research shows this is possible (see https://arxiv.org/pdf/2111.15602.pdf). The authors find words related to food insecurity using semantic frame parsing. After which, they count the occurrence of these words to create features. The features are put into a linear classifier. We wanted to apply more advanced methods and use local news sources (which we suppose contain more localized information). We used BERTopic on over a million articles scraped from Somali news websites. Because articles are both in English and Somali, we use a multilingual sentence encoder (LaBSE, which outperforms newer models in Somali). The results are quite nice. For example, topics most strongly correlated with known conflict casualty data are topics about terrorist attacks, car bombings, etc. And topics most negatively correlated with known conflict casualty data are about peace talks. We can also get an indication of food price development and forced migration. Most importantly, we can track the development of topics relating to food insecurity over time. While topic modelling cannot replace evidence-based food insecurity assessment, it can give a quick insight into a local situation when 'hard data' is lacking.

+ I applaud you on your success with BERTopic. The package is incredibly clean and easy to use, and the method works well with little parameter tuning. To me, the fact that you were able to deliver such a useful tool on your own is incredible, especially in the field of NLP, which is dominated by large organizations such as Google and Meta. "
