P2P Semantic Coordination for Collective Knowledge Organization

Abstract

In this chapter, we present a P2P coordination approach for setting up and exploiting collective peer knowledge provided by autonomously emerging semantic communities. This approach aims at providing a practical means for allowing a peer to move from a restricted peer knowledge space, where it is considered as a single agent with its personal knowledge, towards an intermediate collective knowledge space, where it is considered as a member of a community storing a part of the overall collective knowledge, up to a final collective peer-knowledge space, where the peer builds its personal and coordinated view of the collective knowledge of interest harvested from the underlying communities. In this respect, ontologies and Semantic matching techniques are exploited to set up collective knowledge and to effectively enforce distributed resource sharing.
