Semantic Community in a Peer-to-Peer Network

摘要

The problem of knowledge sharing is eminent in the P2P area. In this paper, we propose a general framework, called semantic community, which is conceived for supporting dynamic ontology-based knowledge sharing and evolution in P2P systems. The knowledge sharing and evolution processes in semantic community are based on peer ontologies which are describing the knowledge of each peer, and on interactions among peers. This paper exploits an ontology matching algorithm to identify semantic affinity of two concepts.According to the semantic affinity threshold, the founder has to evaluate which peers are admitted in the community.
