Data mediation towards semantic web service interoperability

Abstract

The interoperability of heterogeneous information systems via semantic web services keeps a real challenge. We propose a service oriented architecture for developing the interoperability mechanism in the information systems of companies. The core of this architecture is a web services semantic mediation infrastructure using a semantic model and the SAWSDL language for resolving mismatches. In the setting of this paper, we present our global approach then retail the data mediation and the semantic model which is based on the ontologies and the notion of context.

Information Integration of Drug Discovery and Clinical Studies to Support Complex Queries Using an Information Supply Chain Framework

“…Answering questions in clinical studies requires integration of information which in many cases may be held in different institutions, in different formats and in various semantic contexts. Such diversity hinders constructing generic ontology that avoids semantic conflicts [1], yet are necessary to enable sharing of data and information across domains, within a context [2,3].…”
