Mind Your Vocabulary: Query Mapping Across Heterogeneous Information Sources
Summary: Translates constraint-based queries across heterogeneous sources via user mappings to adapt operators and formats. TDQM uses top-down query-tree mapping with semantic relaxations, yielding minimal, compact rewritings and avoiding DNF expansion. (summarized by gpt-5-nano on Feb 09 2026)
