DELTA: Pre-train a Discriminative Encoder for Legal Case Retrieval via Structural Word Alignment


title_rewrite


The authors propose an approach to enhance the understanding of case relevance in legal case retrieval, integrating lexical matching, semantic retrieval, and learning-to-rank techniques, along with heuristic pre-processing and post-processing methods.

Enhancing Legal Case Retrieval through Improved Understanding of Case Relevance



This paper introduces a novel method for automatically constructing large-scale, high-quality datasets of synthetic query-candidate pairs to enhance the performance of legal case retrieval (LCR) systems, particularly in asymmetric retrieval scenarios where user queries are short and concise.
