This paper proposes an algorithm applied in semantic P2P network based on the description logics with the purpose for realizing the concepts distribution of resources, which makes the resources semantic locating easy. With the idea of the consistent hashing in the Chord, our algorithm stores the addresses and resources with the values of the same type to select instance. In addition, each peer has its own ontology, which will be completed by the knowledge distributed over the network during the exchange of CHGs (classification hierarchy graphs). The hierarchy classification of concepts allows to find matching resource by querying to the upper level concept because the all concepts described in the CHG have the same root This paper proposes an algorithm applied in semantic P2P network based on the concepts distribution of resources, which makes the resources semantic locating easy.
