MapMerge: Correlating Independent Schema Mappings

Summary: MapMerge correlates independently designed, smaller-scope schema mappings into coherent complex mappings, enabling modular “divide-and-merge” construction. A novel cross-schema instance similarity measure shows improved preservation of data associations and mapping quality. (summarized by gpt-5.6-luna on Jul 24 2026)
