The first step to integrate multiple data sources is to decrease the heterogeneity between their schemas. This task can be facilitated if data source schemas are represented as ontologies. In this case, ontology matching enables the identification of correspondences between elements of data source schemas. We propose an ontology matching approach to improve(More)

Information exchange occurs through the establishment of schema mappings between local schemas. To help matters, ontologies have been considered as uniform representation of local schemas (i.e., peer ontologies). Consequently, ontology matching(More)
