Toward Web portals integration through semantic Web services

Nowadays Web users have a vast amount of information resources at their disposal. These information resources include not only the data on the Web but also Web portals which offer users services such as flight ticket booking. Internet users demand integrated access to all information resources available on the Web; so both the services and the Web data have to be incorporated in integration efforts. Most of the known integration approaches ignore the services and operational aspects offered by Web portals, moreover, they are mostly ad hoc and hardly customized solutions. This paper tries to tackle the above problem proposing a service-oriented architecture for Web data and service integration. Firstly, it proposes a service-oriented platform-independent architecture, and, secondly, it presents a specific deployment of such architecture for data and service integration on the Web using semantic Web services implemented with the WSMO (Web services modeling ontology).
