%X A semantic overlay network structure, which is based on structured P2P routing mechanism and topic partition, is presented. By assigning nodeid and key according to the topic, SSON collects the nodes with the similar topic into a cluster. When searching content, it first finds the cluster with the structured P2P routing mechanism, and then it limits the query in the range of cluster. Compared with the semantic overlay network based on unstructured P2P network, this structure provides more efficient search for topic cluster. At the same time, it provides the structured P2P network with effective approach to search for content based on complicated queries, and it realizes the semantic search and dramatically increases the search recall.
