MediWeb: um integrador semântico de dados na web baseado em mediador.

Abstract

Semantic Web is a next web generation vision, where information is integrated, processed, interpreted and interchanged among machines in order to provide more sophisticated applications for web users. This vision, considered to be the third web generation, creates large challenges for the scientific community. One of the main obstacles that has to be overcome is semantic heterogeneousness, which creates major problems for interoperability and data integration on the web. In this dissertation, we specify a semantic data integrator on the web based on mediator architecture using the ontological approach to support the semantic tasks. We have also used XML and DAML + OIL languages to propose a n-layer architecture that can provide syntactical, structural and semantical interoperability as defined in the Semantic Web specification.
