Abstract :
The problem of knowledge sharing is eminent in the P2P area. In this paper, we propose a general framework, called HELIOS (Helios Evolving Interaction-based Ontology knowledge Sharing), conceived for supporting dynamic ontology-based knowledge sharing and evolution in P2P systems. The knowledge sharing and evolution processes in HELIOS are based on peer ontologies, describing the knowledge of each peer, and on interactions among peers, allowing information search and knowledge acquisition/ extension, according to pre-defined query models and semantic techniques for ontology matching.
