Overview

MAP-Law studies how retrieval should stop, continue, or be supplemented during multi-turn legal consultation.

Main Idea

The framework introduces retrieval criteria based on:

  • element coverage,
  • evidence coverage,
  • marginal gain.

Role and Status

I contributed to the project as a core developer within the broader LAW MASTER direction. The technical write-up is currently in preprint and submission-preparation stage.
