NL-Augmenter 🦎 → 🐍

The NL-Augmenter is a collaborative effort intended to add transformations of datasets dealing with natural language. Transformations augment text datasets in diverse ways, including: randomizing names and numbers, changing style/syntax, paraphrasing, KB-based paraphrasing ... and whatever creative augmentation you contribute. We invite submissions of transformations to this framework by way of GitHub pull request.

Some Ideas for Transformations

If you need inspiration for what transformations to implement, check out GEM-benchmark#75, where some ideas and previous papers are discussed. So far, contributions have focused on morphological inflections, character level changes, and random noise. The best new pull requests will be dissimilar from these existing contributions.

Installation

Requirements

• Python 3.7

Instructions

# When creating a new transformation, replace this with your forked repository (see below)
git clone https://github.com/GEM-benchmark/NL-Augmenter.git
cd NL-Augmenter
python setup.py sdist
pip install -e .
pip install https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-3.0.0/en_core_web_sm-3.0.0.tar.gz

How do I create a transformation?

Setup

First, fork the repository in GitHub! 🍴

Your fork will have its own location, which we will call PATH_TO_YOUR_FORK. Next, clone the forked repository and create a branch for your transformation, which here we will call my_awesome_transformation:

git clone $PATH_TO_YOUR_FORK
cd NL-Augmenter
git checkout -b my_awesome_transformation

We will base our transformation on an existing example. Create a new transformation directory by copying over an existing transformation. You can choose to copy from other transformation directories depending on the task you wish to create a transformation for. Check some of the existing pull requests and merged transformations first to avoid duplicating efforts or creating transformations too similar to previous ones.

cd nlaugmenter/transformations/
cp -r butter_fingers_perturbation my_awesome_transformation
cd my_awesome_transformation

Creating a transformation

1. In the file transformation.py, rename the class ButterFingersPerturbation to MyAwesomeTransformation and choose one of the interfaces from the interfaces/ folder. See the full list of options here.
2. Now put all your creativity in implementing the generate method. If you intend to use external libraries, add them with their version numbers in requirements.txt
3. Update my_awesome_transformation/README.md to describe your transformation.

Testing and evaluating (Optional)

Once you are done, add at least 5 example pairs as test cases in the file test.json so that no one breaks your code inadvertently.

Once the transformation is ready, test it:

pytest -s --t=my_awesome_transformation

If you would like to evaluate your transformation against a common 🤗HuggingFace model, we encourage you to check evaluation

Code Styling To standardized the code we use the black code formatter which will run at the time of pre-commit. To use the pre-commit hook, install pre-commit with pip install pre-commit (should already be installed if you followed the above instructions). Then run pre-commit install to install the hook. On future commits, you should see the black code formatter is run on all python files you've staged for commit.

Submitting

Once the tests pass and you are happy with the transformation, submit them for review. First, commit and push your changes:

git add transformations/my_awesome_transformation/*
git commit -m "Added my_awesome_transformation"
git push --set-upstream origin my_awesome_transformation

Finally, submit a pull request. The last git push command prints a URL that can be copied into a browser to initiate such a pull request. Alternatively, you can do so from the GitHub website.

✨ Congratulations, you've submitted a transformation to NL-Augmenter! ✨

How do I create a filter?

We also accept pull-requests for creating filters which identify interesting subpopulations of a dataset. The process to add a new filter is just the same as above. All filter implementations require implementing .filter instead of .generate and need to be placed in the filters folder. So, just the way transformations can transform examples of text, filters can identify whether an example follows some pattern of text! The only difference is that while transformations return another example of the same input format, filters simply return True or False! For step-by-step instructions, follow these steps.

BIG-Bench 🪑

If you are interested in NL-Augmenter, you may also be interested in the BIG-bench large scale collaborative benchmark for language models.

Most Creative Implementations 🏆

After all pull-requests have been merged, 3 of the most creative implementations would be selected and featured on this README page and on the NL-Augmenter webpage.
