OmniMatch: Joinability Discovery in Data Products

Summary: OmniMatch: joinability discovery for curated data products that fuses multiple column-pair similarity measures with a self-supervised GNN exploiting graph neighborhood to boost recall. Automated negative-pair generation raises precision, yielding up to 14% F1/AUC gains without per-metric thresholds. (summarized by gpt-5-mini on Feb 09 2026)
