## 🛠 Installation

Install from PyPI:

```bash
pip install tweetopic
```

## 👩‍💻 Usage ([documentation](https://centre-for-humanities-computing.github.io/tweetopic/))

Train your a topic model on a corpus of short texts:

```python
from tweetopic import DMM
from sklearn.feature_extraction.text import CountVectorizer
from sklearn.pipeline import Pipeline

# Creating a vectorizer for extracting document-term matrix from the
# text corpus.
vectorizer = CountVectorizer(min_df=15, max_df=0.1)

# Creating a Dirichlet Multinomial Mixture Model with 30 components
dmm = DMM(n_components=30, n_iterations=100, alpha=0.1, beta=0.1)

# Creating topic pipeline
pipeline = Pipeline([
    ("vectorizer", vectorizer),
    ("dmm", dmm),
])
```

You may fit the model with a stream of short texts:

```python
pipeline.fit(texts)
```

To investigate internal structure of topics and their relations to words and indicidual documents we recommend using [topicwizard](https://github.com/x-tabdeveloping/topic-wizard).

Install it from PyPI:

```bash
pip install topic-wizard
```

Then visualize your topic model:

```python
import topicwizard

topicwizard.visualize(pipeline=pipeline, corpus=texts)
```
