A Quantum-Leap into Schema Matching: Beyond 1-to-1 Matchings
Summary: Models 1:N/N:1 global schema matching as an optimization problem; proves NP-hard. Translates to minimizing a rational-valued binary-variable function, enabling quantum algorithms for global matching; preliminary experiments show feasibility. (summarized by gpt-5-nano on Feb 09 2026)
