MapMerge: Correlating Independent Schema Mappings

Summary: MapMerge introduces an operator to correlate independently designed mappings into a larger target, enabling divide-and-merge. It uses an instance-similarity metric to measure data-association preservation and shows improved mapping quality on real/synthetic data. (summarized by gpt-5-nano on Feb 09 2026)
