On combining a semantic engine and flexible network policies for P2P knowledge sharing networks

Peer-to-Peer (P2P) systems have recently become popular for content sharing, and a number of different approaches have been studied to perform effective content retrieval in such networks. In this paper, we discuss how conventional P2P network policies for content retrieval could be combined with a semantic engine component to enforce peer-based knowledge sharing. The semantic engine exploits peer ontologies for providing a semantically rich representation of peer knowledge, and matching techniques for comparing ontologies of different peers for knowledge sharing and discovery purposes.
