Algebras of ontology alignment relations

Algebras of ontology alignment relations

This video was recorded at 7th International Semantic Web Conference (ISWC), Karlsruhe 2008. Correspondences in ontology alignments relate two ontology entities with a relation. Typical relations are equivalence or subsumption. However, different systems may need different kinds of relations. We propose to use the concepts of algebra of relations in order to express the relations between ontology entities in a general way. We show the benefits in doing so in expressing disjunctive relations, merging alignments in different ways, amalgamating alignments with relations of different granularity, and composing alignments.
