Cast NLP data as multiangular DeepA2 datasets and integrate these in training pipeline

Project description

unit tests code quality Code Climate maintainability PyPI version

Deep Argument Analysis (deepa2)

This project provides deepa2, which

  • 🥚 takes NLP data (e.g. NLI, argument mining) as ingredients;
  • 🎂 bakes DeepA2 datatsets conforming to the Deep Argument Analysis Framework;
  • 🍰 serves DeepA2 data as text2text datasets suitable for training language models.

There's a public collection of 🎂 DeepA2 datatsets baked with deepa2 at the HF hub.

The Documentation describes usage options and gives background info on the Deep Argument Analysis Framework.


Integrating deepa2 into Your Training Pipeline

  1. Install deepa2 into your ML project's virtual environment, e.g.:
source my-projects-venv/bin/activate 
python --version  # should be ^3.7
python -m pip install deepa2
  1. Add deepa2 preprocessor to your training pipeline. Your training script may look like, for example:

# configure and activate environment

# download deepa2 datasets and 
# prepare for text2text training
deepa2 serve \
    --path some-deepa2-dataset \    # <<< 🎂
    --export_format csv \
    --export_path t2t \             # >>> 🍰

# run default training script, 
# e.g., with 🤗 Transformers
python .../ \
    --train_file t2t/train.csv \    # <<< 🍰
    --text_column "text" \
    --summary_column "target" \

# clean-up
rm -r t2t
  1. That's it.

Create DeepA2 datasets with deepa2 from existing NLP data

Install poetry.

Clone the repository:

git clone

Install this package from within the repo's root folder:

poetry install

Bake a DeepA2 dataset, e.g.:

poetry run deepa2 bake \\
  --name esnli \\                   # <<< 🥚
  --debug-size 100 \\
  --export-path ./data/processed    # >>> 🎂  

Contribute a DeepA2Builder for another Dataset

We welcome contributions to this repository, especially scripts that port existing datasets to the DeepA2 Framework. Within this repo, a code module that transforms data into the DeepA2 format contains

  1. a Builder class that describes how DeepA2 examples will be constructed and that implements the abstract builder.Builder interface (such as, e.g., builder.entailmentbank_builder.EnBankBuilder);
  2. a DataLoader which provides a method for loading the raw data as a 🤗 Dataset object (such as, for example, builder.entailmentbank_builder.EnBankLoader) -- you may use deepa2.DataLoader as is in case the data is available in a way compatible with 🤗 Dataset;
  3. dataclasses which describe the features of the raw data and the preprocessed data, and which extend the dummy classes deepa2.RawExample and deepa2.PreprocessedExample;
  4. a collection of unit tests that check the concrete Builder's methods (such as, e.g., tests/;
  5. a documentation of the pipeline (as for example in docs/

Consider suggesting to collaboratively construct such a pipeline by opening a new issue.
