HAMSTER: Using Search Clicklogs for Schema and Taxonomy Matching

Summary: Unsupervised schema matching to integrate many sources into a warehouse schema via clicklogs. HAMSTER uses click-through distributions over keyword-queries to align schema elements; outperforms traditional schema- and instance-based matching. (summarized by gpt-5-nano on Feb 09 2026)
