Cross-enterprise collaboration has emerged as a key survival factor in today´s global markets. Semantic Web technologies are the basis to establish enterprise interoperability including data mediation support and automatic composition of services. Capabilities of services are semantically described and reasoning techniques support the discovery and selection of services at run-time. In contrast to Semantic Web technologies that cover interactions between (technical) services, human collaboration emerges based on social preferences. Social networks have become a mass phenomenon and are increasingly
used in businesses and professional environments. In a manner similar to service-oriented systems, they enable flexible discovery and dynamic collaboration between participants. In this paper, we discuss the concept of social overlays forWeb service based collaboration
infrastructures. This mechanism enables information flows between actors in order to allow for flexible group formation in highly dynamic large-scale networks. We present the implementation of a trusted information sharing framework and demonstrate how people adaptively share information according to the strength of social relations using SOA concepts. We evaluate technical concepts with in-depth experiments.
