Ontology-based integration for Sharing Knowledge over the Web

, and . DIWeb2004. Third International Workshop on Data Integration over the Web, Proceedings, (2004)

Abstract

In this paper, we propose a methodology developed in theframework of the VISPO project for engineering a three-layer ontology,based on the conceptualization, integration, synthesis and categorizationof XML data descriptions provided by a number of sources in a virtualdistrict, where di®erent enterprises cooperate for business purposes. On-tologies are proposed as an unifying framework for di®erent viewpointsby providing a shared understanding in a subject domain. Our method-ology generates an ontology organized into concepts and concept rela-tionships at di®erent levels of detail, to provide multiple, uni¯ed views ofthe datasources containing heterogeneous information about the domainof interest.
