The problem of defining efficient techniques for knowledge representation (KR) is becoming more and more a challenging topic in both academic and industrial community. The Semantic Web needs of formal knowledge representations for implementing useful services and put in common the different views between man and machines. In this framework, we assume that new approaches for knowledge definition and representation may be useful, in particular the ones based on the concept of ontology. In this paper we propose novel techniques and tools for ontology definition and management. In particular, we propose a suitable model for representing knowledge and a system based on peer-to-peer (P2P) paradigm to share general and domain knowledge. The network knowledge is exposed using a Web Service and it can be used by intelligent Web agents.
