Code for the paper "Legally Enforceable Hate Speech Detection for Public Forums" published in Findings of EMNLP 2023 (paper link)

Generating silver data

1. Sample easy negatives using dataset/sampling negatives.ipynb
2. Generate the labels with silver label generation.ipynb
3. Unify the natural text generations with legal annotations with silver data refactor.ipynb
4. (Optional) Run the notebook data/construct final dataset.ipynb to generate prompt files into the directories data/train and data/test.

Zero-shot experiments

All code is available under zeroshot. This requires the prepared data, or you can use the prompt formatting directly from data/construct final dataset.ipynb.

Self-training

Run the notebook data/construct final dataset.ipynb to generate prompt files into the directories data/train and data/test. This notebook requires the data files.
