Many collaborative organizations require advanced semantic interoperability tools to enable cooperation and communication across distributed Web Information Systems (WIS). Adopting the service-oriented technology, they have improved interoperability at the application level by exporting WIS functionalities as Web services. Furthermore, in order to support effective peer-to-peer collaboration, they require semantic interoperability techniques for service discovery and sharing. In this paper, we focus on semantic interoperability issues for distributed collaboration and provide techniques for building a service semantic overlay, across heterogeneous WIS. In particular, semantic links among peers that offer comparable services in a given domain are defined and maintained over the time. The service semantic overlay is ontology-based for formally organizing the shared services to enhance the capability of service interchange and interoperation among the collaborative systems. The approach and a preliminary experimentation have been proposed to demonstrate practical benefits in the framework of the ESTEEM (Emergent Semantics and cooperaTion in multi-knowledgE EnvironMents) project. © 2008 Springer-Verlag Berlin Heidelberg.
