Schema Extraction for Tabular Data on the Web

Summary: CRF-based schema extraction for tabular Web data using a novel logarithmic binning feature encoding to infer table construction from nearby rows. Extends beyond HTML tables to full tables (including spreadsheets), extracting row groups and surpassing WebTables in schema accuracy. (summarized by gpt-5-nano on Feb 09 2026)
