This is the official repository for the paper "Tox-BART: Leveraging Toxicity Attributes for Explanation Generation of Implicit Hate Speech."

Run the following command to initialize the directory:

git clone https://github.com/LCS2-IIITD/TOXBART.git
cd TOXBART

We suggest using conda to manage virtual environments and ease-of-access.

-> Python >=3.9
-> PyTorch >=2.0
-> Transformers

Kindly go through the following instructions to download the required datasets:

• SBIC: Need to download from the attached link and place in the data directory.
• LatentHatred: Need to download from the attached link and place in the data directory, in addition to the already present data.
• Jigsaw Unintended Bias: Need to download from the attached link and place in the tox_bert/jigsaw-data directory.
• StereoKG: Need to download from the attached link and place in the data directory.
• ConceptNet: Use the following command wget https://s3.amazonaws.com/conceptnet/downloads/2019/edges/conceptnet-assertions-5.7.0.csv.gz in the data directory. To unzip the file, use gunzip conceptnet-assertions-5.7.0.csv.gz.

To train the toxic-bert model, run the train.py file in the tox_bert directory. You can also run an inference using test.py to see how well it performs in terms of the RMSE scores.

Kindly follow the running instructions present in each {train, test}.py file to run the knowledge or configuration experiments.

Although the code uses relative paths and in most cases asks the user to enter the paths (using argparse), we encourage you to not add any depth to the current directory structure. In case, you encounter any issues with the paths, cross-check if your data is in the correct directory.

Here is a an approximate view of how the directories are structured in this repository.
