New framework improves legal AI by decomposing complex questions

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework called Decompose-and-Refine (DaR) to improve legal question answering using large language models. DaR addresses the challenge of accurately retrieving relevant legal statutes for complex, multi-hop questions by breaking them down into smaller, manageable sub-questions. It then uses parametric knowledge to refine queries for each sub-question, ensuring better alignment with statutory text and reducing the risk of hallucination. Evaluations on the Korean KoBLEX benchmark showed DaR enhances both retrieval accuracy and final answer quality. AI

IMPACT Enhances LLM accuracy in legal applications by improving statutory grounding and reducing hallucinations.

    Decompose-and-Refine: Structured Legal Question Answering with Parametric Retrieval

    arXiv:2605.24454v1 Announce Type: new Abstract: Large language models (LLMs) have shown strong performance in the legal domain, demonstrating notable potential in Legal Question Answering (LQA). However, unlike general QA, LQA requires answers that are not only accurate but also …
