Our method has the following features: i) the matching is carried out at the schema level; ii) the alignment of the ontologies is performed without previous agreement on the semantics of the terminology used by each ontology; iii) both the linguistic and the contextual features of an ontology concept are considered; iv) WordNet is incorporated into the linguistic analysis phase; v) heuristic knowledge is integrated into the contextual analysis phase; and vi) reasoning rules based on the domain-independent relationships subclass, superclass, equivalentclass, sibling, and each ontology concept’s property list are used to infer new relationships among concepts. We describe a set of experiments and provide an evaluation of the results that shows the accuracy of our system.
