SANTOS: Relationship-based Semantic Table Union Search
Summary: SANTOS: relationship-based semantic table union search; unionability via inter-column relationships and column semantics. Two methods: KB-driven relation extraction and a data-lake synthesized KB; outperforms column-based union search on open benchmarks. (summarized by gpt-5-nano on Feb 09 2026)
