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

In three linesDaR (Decompose-and-Refine) is a framework for answering complex legal questions by decomposing them into atomic sub-questions and generating statute-aligned parametric queries. Evaluated on KoBLEX (Korean multi-hop benchmark) using Qwen3-32B and Gemma3-27B, DaR improves retrieval accuracy and answer quality while reducing hallucinations.
