Magneto: Combining Small and Large Language Models for Schema Matching

Summary: Magneto uses a two-phase retrieval+reranking pipeline that leverages cheap small LMs to generate candidates and powerful LLMs to rerank, trading minimal compute for high matching accuracy. Novel contributions: LLM-synthesized self-supervised SLM fine-tuning, effective reranking prompts, and a challenging biomedical benchmark. (summarized by gpt-5-mini on Feb 09 2026)
