Abstract: Maintenance of semantic information and selection of intelligence route in the P2P semantic overlay network are challenging problems. According to the small world theory in network, a new P2P semantic route model with classified nodes was proposed. First, node ontology was built in order to describe the network structure and the information in the node. Then, the formation of message routing and the method of nodes classification were created. At last, the algorithm of similar knowledge Searching and the algorithms of message routing were imported to support semantic information querying and routing. It is shown, through experimental evaluation, that the model and its algorithm can efficiently support the semantic searching functionalities in the P2P network.
