Code for the paper: ConDA: Contrastive Domain Adaptation for AI-generated Text Detection accepted at IJCNLP-AACL 2023 paper link.

🌟 Great News! [Nov 4, 2023] 🌟 Our paper won the Outstanding Paper Award at IJCNLP-AACL 2023 held in Bali, Indonesia.

Setup

Set up a separate environment and install requirements via pip install -r requirements.txt

Make directories for the models, output logs and huggingface model files.

mkdir models huggingface_repos output_logs

Download roberta-base from here and/or roberta-large from here and place these repositories in huggingface_repos.

contrast_training_with_da.py is the ConDA training script. The multi_domain_runner.py is the runner script for training ConDA models. Update the arguments in multi_domain_runner.py to train models as needed.

Use the evaluation.py script for evaluating models. Change arguments within the evaluation.py script as needed.

TuringBench

Files should be split into 3 jsonl splits: train, valid, test. Each line in the jsonl is a data instance with text and label fields.
