Alignement des ontologies : Utilisation de WordNet et une nouvelle mesure structurelle

Semantic interoperability between heterogeneous sources of information is significant problems because of the number growing of sources of information available on the Web. The use of ontology is a very promising way to allow interoperability, only ontology them self can be heterogeneous. The alignment of ontology is the core of this interoperability, however the automatic generation of the mappings between two ontology is of an extreme difficulty which is due to the divergences (conceptual, practices, etc.) between communities different of development of ontology. This work is a proposal of an algorithm of alignment of two ontology of the same field by using various techniques, in particular we use WordNet and we introduce a new measure of structural similarity between two entities of two deferent ontology which is based on the structural position of the entities to compare within their ontology.
