Domain-Specific Fine-Tuning On Legal Corpora Performance On The Zero-Shot Performance Of Baichuan-2 On The Legalbench

Abstract

Abstract: This report synthesises findings from 10 peer-reviewed papers addressing the following research question: How does domain-specific fine-tuning on legal corpora affect the zero-shot performance of Baichuan-2 on the LegalBench benchmark compared to models fine-tuned on general domains. Realizing the recent advances in Natural Language Processing (NLP) to the legal sector poses challenging problems such as extremely long sequence lengths, specialized vocabulary that is usually only understood by legal professionals, and high amounts of data imbalance. The. 0 claims were extracted from source literature; 0 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 4.2/10. This report is a machine-generated literature synthesis and does not constitute original research.
