To make the DHT-based structured P2P network to support semantic retrieval,a search algorithm SOC(semantic ontology chord) based on DHT and ontology is proposed.Aimed at the problems of the exact matched key search in structured P2P network,this algorithm improves the resources identifier in the DHT,uses the ontology to conduct the fuzzy query,puts the nodes of similar interest in the neighboring position,and improves recall of the resources search in the P2P network.The results of simulation experiment which uses the PeerSim simulator indicated that this algorithm achieve higher recall than chord with the increase of nodes and data.
