Approximate Query Translation Across Heterogeneous Information Sources

Summary: Framework for approximate Boolean query translation across heterogeneous sources, with a closeness metric blending precision and recall. Rule-based semantic units encode mappings; queries rewritten into units yield optimal translations under practical assumptions, demonstrated by a case study.
