A scalable framework for distributed ontologies

초록

In large-scale Peer-to-Peer (P2P) systems, information is usually generated decentralized. An architecture that enables applications to have a unified view on various information sources is currently attracting enormous attention. For building that architecture, many P2P oriented applications focus on resolving two challenges. The first one is making available information sources have a uniform format and the second is to allow querying on that information without regarding the heterogeneity of the underlying systems. In this paper, we propose a framework for integrating information from heterogeneous sources by exploiting two new technologies: the Semantic Web and the Grid computing. In our scenario, we fabricate the Semantic Web service on the top of Grid Services. Each data provider becomes an autonomous node in Virtual Organization of the Grid system. The implementation and experimental result demonstrate the feasibility of our approach. © 2008 Springer-Verlag Berlin Heidelberg.
