Abstract:
Semantics of schema models is not explicit but always hidden in their structures and labels. To obtain semantic interoperability we need to make their semantics explicit by taking into account both the interpretation of the labels and the structures described by the arcs. We address in this paper the issue of semantic interoperability between systems relying on semantically heterogeneous hierarchies, having been designed for the purpose of independent specific goals and activities. Given a set of generalization hierarchies, our approach gives much emphasis on semantics added-value by ”emerging” the intended informal meaning of concepts, we rely on Wordnet lexical repository. In the first part of the paper, we provide a rigorous logical framework for representing and automatically reasoning on generalization hierarchies except their formalism (UML, ER diagram, etc). Then, we describe The SEM-INTEROP algorithm that consists on two main steps: semantic interpretation and semantic compar
aison.
