Techniques for discovering correspondences between ontologies

Abstract

Ontology Alignment is required to facilitate ontology reuse and to enable interoperability between ontology-enabled systems and applications. Aligning a pair of ontologies involve finding the correspondences among their entities. While equivalence correspondences tell us which pairs of entities have the same semantic meaning, non-equivalence correspondences tell us how pairs of entities are semantically related. In this paper, we survey techniques used to find equivalence correspondences efficiently as well as techniques used to find non-equivalence correspondences effectively. We provide a critique of each category of methods and highlight the areas worthy of more in-depth research.
