Lean Finder V2 enhances Mathlib semantic search with query disambiguation

Researchers have developed Lean Finder V2, an advanced semantic search framework designed for Mathlib, a large mathematical library. This new system employs a combination of model-level adversarial training and input-level query rewriting to effectively disambiguate user queries, which are often short and implicit. Lean Finder V2 significantly outperforms previous Mathlib search engines, achieving at least an 11% relative improvement on the MathlibQR benchmark and demonstrating superior performance on unlabeled queries from both human mathematicians and coding agents. Its integration with Claude Code has also shown to enhance success rates in downstream theorem-proving tasks. AI

IMPACT Improves AI's ability to interact with and utilize formal mathematical knowledge bases.

    Lean Finder V2: Semantic Search for Mathlib That Disambiguates User Queries

    We introduce Lean Finder V2, a semantic search framework for Mathlib that disambiguates user queries through complementary model-level adversarial training and input-level query rewriting. Human mathematicians and coding agents rarely search Mathlib by providing detailed context.…
