MAP-Law: Coverage-Driven Retrieval Control for Multi-Turn Legal Consultation
The recently introduced MAP-Law framework offers a coverage-driven method for managing retrieval during multi-turn legal consultations. It conceptualizes the consultation as a regulated retrieval operation over a combined structured state that includes issue nodes, legal element nodes, and evidence nodes. Following each round of retrieval, the agent evaluates Element Coverage, Evidence Coverage, and Marginal Gain to determine if additional retrieval is necessary. This strategy seeks to resolve the limitations of fixed retrieval depth or imprecise heuristic control found in current legal agents, which may result in inadequate support or excessive information retrieval. The research is available on arXiv with the identifier 2605.01486v1.
Key facts
- MAP-Law is a coverage-driven framework for retrieval control in multi-turn legal consultation.
- It models consultation as a controlled retrieval process over issue nodes, legal element nodes, and evidence nodes.
- After each retrieval round, the agent computes Element Coverage, Evidence Coverage, and Marginal Gain.
- The framework addresses limitations of fixed retrieval depth or coarse heuristic control.
