Stitching Web Tables for Improving Matching Quality

Summary: Stitch similar-site web tables into larger, more homogeneous ones before KB/base-table matching to boost alignment. Evaluates T2K Match and COMA; stitching yields 0.38 F1 gain for T2K and 0.14 for COMA, reducing corpus from 5M to ~100k stitched tables. (summarized by gpt-5-nano on Feb 09 2026)
