Data Integration with Uncertainty

Summary: Proposes probabilistic schema mappings to handle uncertainty in data integration: approximate mappings, keyword queries, and imprecise extraction. Formalizes two semantics (by-table and by-tuple), analyzes query complexity, and yields top-k algorithms. (summarized by gpt-5-nano on Feb 09 2026)
