MAP-Law framework optimizes multi-turn legal consultation with coverage-driven retrieval

Researchers have developed MAP-Law, a novel framework designed to improve retrieval control in multi-turn legal consultations. This system models the consultation process as a structured retrieval over issue, legal element, and evidence nodes. By calculating Element Coverage, Evidence Coverage, and Marginal Gain after each retrieval, MAP-Law intelligently decides whether to continue searching, redirect, or generate a response, making the stopping decision auditable and aligned with legal argumentation.
