Abstract
The present invention relates to computer implemented methods and system for determining correspondences between terms in two or more ontologies. The methods and systems are designed to accept as inputs ontologies in Web Ontology Language (OWL) syntax or any other ontology syntax, to calculate a similarity measure between terms in the ontologies, extract an alignment based on this similarity measure, and verify this alignment according to the semantics contained in the ontologies. This process is designed to be executed iteratively until the similarity measures converge, or until another suitable finalization condition is met. The result of these methods and of the systems implementing these methods is an alignment between two or more ontologies establishing semantic correspondences between the terms in the ontologies.
