Anish Pahilajani, Samyak Jain, Devasha Trivedi · 2024
This paper presents our submission to the Se-mEval 2024 Task 5: The Legal Argument Reasoning Task in Civil Procedure.We present two approaches to solving the task of legal answer validation, given an introduction to the case, a question and an answer candidate.Firstly, we fine-tuned pre-trained BERT-based models and found that models trained on domain knowledge perform better.Secondly, we performed few-shot prompting on GPT models and found that reformulating the answer validation task to be a multiple-choice QA task remarkably improves the performance of the model.Our best submission is a BERT-based model that achieved the 7th place out of 20.
