User guide

Overview

SummVis is a tool for analyzing abstractive summarization systems. It provides fine-grained insights on summarization models, data, and evaluation metrics by visualizing the relationships between source documents, reference summaries, and generated summaries, as illustrated in the figure below.

Interface

The SummVis interface is shown below. The example displayed is the first record from the CNN / Daily Mail validation set.

Components

(a) Configuration panel
(b) Source document (or reference summary, depending on configuration)
(c) Generated summaries (and/or reference summary, depending on configuration)
(d) Scroll bar with global view of annotations

Annotations

N-gram overlap: Word sequences that overlap between the document on the left and the selected summary on the right. Underlines are color-coded by index of summary sentence.
Semantic overlap: Words in the summary that are semantically close to one or more words in document on the left.
Novel words: Words in the summary that do not appear in the document on the left.
Novel entities: Entity words in the summary that do not appear in the document on the left.

Limitations

Currently only English text is supported.

Installation

IMPORTANT: Please use python>=3.8 since some dependencies require that for installation.

# Requires python>=3.8
git clone https://github.com/robustness-gym/summvis.git
cd summvis
pip install -r requirements.txt
python -m spacy download en_core_web_sm

Installation takes around 2 minutes on a Macbook Pro.

Quickstart

Follow the steps below to start using SummVis immediately.

1. Download and extract data

Download our pre-cached dataset that contains predictions for state-of-the-art models such as PEGASUS and BART on 1000 examples taken from the CNN / Daily Mail validation set.

mkdir data
mkdir preprocessing
curl https://storage.googleapis.com/sfr-summvis-data-research/cnn_dailymail_1000.validation.anonymized.zip --output preprocessing/cnn_dailymail_1000.validation.anonymized.zip
unzip preprocessing/cnn_dailymail_1000.validation.anonymized.zip -d preprocessing/

2. Deanonymize data

Next, we'll need to add the original examples from the CNN / Daily Mail dataset to deanonymize the data (this information is omitted for copyright reasons). The preprocessing.py script can be used for this with the --deanonymize flag.

Deanonymize 10 examples:

python preprocessing.py \\n--deanonymize \\n--dataset_rg preprocessing/cnn_dailymail_1000.validation.anonymized \\n--dataset cnn_dailymail \\n--version 3.0.0 \\n--split validation \\n--processed_dataset_path data/10:cnn_dailymail_1000.validation \\n--n_samples 10

This will take either a few seconds or a few minutes depending on whether you've previously loaded CNN/DailyMail from the Datasets library.

3. Run SummVis

Finally, we're ready to run the Streamlit app. Once the app loads, make sure it's pointing to the right File at the top of the interface.

streamlit run summvis.py

Running with pre-loaded datasets

In this section we extend the approach described in Quickstart to other pre-loaded datasets.

1. Download one of the pre-loaded datasets:

CNN / Daily Mail (1000 examples from validation set): https://storage.googleapis.com/sfr-summvis-data-research/cnn_dailymail_1000.validation.anonymized.zip

CNN / Daily Mail (full validation set): https://storage.googleapis.com/sfr-summvis-data-research/cnn_dailymail.validation.anonymized.zip

XSum (1000 examples from validation set): https://storage.googleapis.com/sfr-summvis-data-research/xsum_1000.validation.anonymized.zip

XSum (full validation set): https://storage.googleapis.com/sfr-summvis-data-research/xsum.validation.anonymized.zip

We recommend that you choose the smallest dataset that fits your need in order to minimize download / preprocessing time.

Example: Download and unzip CNN / Daily Mail

mkdir data
mkdir preprocessing
curl https://storage.googleapis.com/sfr-summvis-data-research/cnn_dailymail_1000.validation.anonymized.zip --output preprocessing/cnn_dailymail_1000.validation.anonymized.zip
unzip preprocessing/cnn_dailymail_1000.validation.anonymized.zip -d preprocessing/

Example: Download and unzip XSum

mkdir data
mkdir preprocessing
curl https://storage.googleapis.com/sfr-summvis-data-research/xsum_1000.validation.anonymized.zip --output preprocessing/xsum_1000.validation.anonymized.zip
unzip preprocessing/xsum_1000.validation.anonymized.zip -d preprocessing/

2. Deanonymize n examples:

Set the --n_samples argument and name the --processed_dataset_path output file accordingly.

Example: Deanonymize 100 examples from CNN / Daily Mail:

python preprocessing.py \\n--deanonymize \\n--dataset_rg preprocessing/cnn_dailymail_1000.validation.anonymized \\n--dataset cnn_dailymail \\n--version 3.0.0 \\n--split validation \\n--processed_dataset_path data/100:cnn_dailymail_1000.validation \\n--n_samples 100

Example: Deanonymize all pre-loaded examples from CNN / Daily Mail (1000 examples dataset):

python preprocessing.py \\n--deanonymize \\n--dataset_rg preprocessing/cnn_dailymail_1000.validation.anonymized \\n--dataset cnn_dailymail \\n--version 3.0.0 \\n--split validation \\n--processed_dataset_path data/full:cnn_dailymail_1000.validation \\n--n_samples 1000

Example: Deanonymize all pre-loaded examples from CNN / Daily Mail (full dataset):

python preprocessing.py \\n--deanonymize \\n--dataset_rg preprocessing/cnn_dailymail.validation.anonymized \\n--dataset cnn_dailymail \\n--version 3.0.0 \\n--split validation \\n--processed_dataset_path data/full:cnn_dailymail.validation

Example: Deanonymize all pre-loaded examples from XSum (1000 examples dataset):

python preprocessing.py \\n--deanonymize \\n--dataset_rg preprocessing/xsum_1000.validation.anonymized \\n--dataset xsum \\n--split validation \\n--processed_dataset_path data/full:xsum_1000.validation \\n--n_samples 1000

3. Run SummVis

Once the app loads, make sure it's pointing to the right File at the top of the interface.

streamlit run summvis.py

Alternately, if you need to point SummVis to a folder where your data is stored.

streamlit run summvis.py -- --path your/path/to/data

Note that the additional -- is not a mistake, and is required to pass command-line arguments in streamlit.

Get your data into SummVis

The simplest way to use SummVis with your own data is to create a jsonl file of the following format:

{"document":  "This is the first source document", "summary:reference": "This is the reference summary", "summary:testmodel1": "This is the summary for testmodel1", "summary:testmodel2": "This is the summary for testmodel2"}
{"document":  "This is the second source document", "summary:reference": "This is the reference summary", "summary:testmodel1": "This is the summary for testmodel1", "summary:testmodel2": "This is the summary for testmodel2"}

The key for the reference summary must equal summary:reference and the key for any other summary must be of the form summary:<summary_name>, e.g. summary:BART. The document and at least one summary (reference, other, or both) are required.

The following additional install step is required.:

python -m spacy download en_core_web_lg

You have two options to load this jsonl file into the tool:

Option 1: Load the jsonl file directly

The disadvantage of this approach is that all computations are performed in realtime. This is particularly expensive for semantic similarity, which uses a Transformer model. At a result, each example will be slow to load (~5-15 seconds on a Macbook Pro).

Place the jsonl file in the data directory. Note that the file must be named with a .jsonl extension.
Start SummVis: streamlit run summvis.py
Select your jsonl file from the File dropdown at the top of the interface.

Option 2: Preprocess jsonl file (recommended)

You may run preprocessing.py to precompute all data required in the interface (running spaCy, lexical and semantic aligners) and save a cache file, which can be read directly into the tool. Note that this script may run for a while (~5-15 seconds per example on a MacBook Pro for documents of typical length found in CNN/DailyMail or XSum), and will be greatly expedited by running on a GPU.

Run preprocessing script to generate cache file
```
python preprocessing.py \\n    --workflow \\n    --dataset_jsonl path/to/my_dataset.jsonl \\n    --processed_dataset_path path/to/my_cache_file
```
You may wish to first try it with a subset of your data by adding the following argument: --n_samples <number_of_samples>.
Copy output cache file to the data directory
Start SummVis: streamlit run summvis.py
Select your file from the File dropdown at the top of the interface.

As an alternative to steps 2-3, you may point SummVis to a folder in which the cache file is stored:

streamlit run summvis.py -- --path <parent_directory_of_cache_file>

Generating predictions

The instructions in the previous section assume access to model predictions. We also provide tools to load predictions, either by downloading datasets with precomputed predictions or running a script to generate predictions for HuggingFace-compatible models. In this section we describe an end-to-end pipeline for using these tools.

Prior to running the following, an additional install step is required:

python -m spacy download en_core_web_lg

1. Standardize and save dataset to disk.

Loads in a dataset from HF, or any dataset that you have and stores it in a standardized format with columns for document and summary:reference.

Example: Save CNN / Daily Mail validation split to disk as a jsonl file.

python preprocessing.py \\n--standardize \\n--dataset cnn_dailymail \\n--version 3.0.0 \\n--split validation \\n--save_jsonl_path preprocessing/cnn_dailymail.validation.jsonl

Example: Load custom `my_dataset.jsonl`, standardize, and save.

python preprocessing.py \\n--standardize \\n--dataset_jsonl path/to/my_dataset.jsonl \\n--save_jsonl_path preprocessing/my_dataset.jsonl

Expected format of my_dataset.jsonl:

{"document":  "This is the first source document", "summary:reference": "This is the reference summary"}
{"document":  "This is the second source document", "summary:reference": "This is the reference summary"}

If you wish to use column names other than document and summary:reference, you may specify custom column names using the doc_column and reference_column command-line arguments.

2. Add predictions to the saved dataset.

Takes a saved dataset that has already been standardized and adds predictions to it from prediction jsonl files. Cached predictions for several models available here: https://storage.googleapis.com/sfr-summvis-data-research/predictions.zip

You may also generate your own predictions using this this script.

Example: Add 6 prediction files for PEGASUS and BART to the dataset.

python preprocessing.py \\n--join_predictions \\n--dataset_jsonl preprocessing/cnn_dailymail.validation.jsonl \\n--prediction_jsonls \\npredictions/bart-cnndm.cnndm.validation.results.anonymized \\npredictions/bart-xsum.cnndm.validation.results.anonymized \\npredictions/pegasus-cnndm.cnndm.validation.results.anonymized \\npredictions/pegasus-multinews.cnndm.validation.results.anonymized \\npredictions/pegasus-newsroom.cnndm.validation.results.anonymized \\npredictions/pegasus-xsum.cnndm.validation.results.anonymized \\n--save_jsonl_path preprocessing/cnn_dailymail.validation.jsonl

3. Run the preprocessing workflow and save the dataset.

Takes a saved dataset that has been standardized, and predictions already added. Applies all the preprocessing steps to it (running spaCy, lexical and semantic aligners), and stores the processed dataset back to disk.

Example: Autorun with default settings on a few examples to try it.

python preprocessing.py \\n--workflow \\n--dataset_jsonl preprocessing/cnn_dailymail.validation.jsonl \\n--processed_dataset_path data/cnn_dailymail.validation \\n--try_it

Example: Autorun with default settings on all examples.

python preprocessing.py \\n--workflow \\n--dataset_jsonl preprocessing/cnn_dailymail.validation.jsonl \\n--processed_dataset_path data/cnn_dailymail
