Abstract: Routing mechanisms is one of key parts in knowledge discovery.The paper proposes a mixed P2P semantic Routing retrievalmodel based on Ontology Knowledge Query Tree.User node can match search term with knowledge of OKQT by querying OKQT on routing nodes,and makes sure the location query fleetly and accurately,and then queries the knowledge which meet user precisely.For the search term which is not match on the internet,by calculating the semanticsimilarity between search term and knowledge in OKQT,and zooming the search term,the corresponding results are given back.Experiment verifies that this method which make sure the location first and query knowledge second can improve the semantic routingefficiency,recall ratio,precision ratio and expansibility.

Key words: semantic routing, knowledge retrieval, OKQT, impureP2P
