摘　　要：P2P语义搜索方法多种多样。首先,制定了一套综述方案,从语义描述方法、覆盖网络结构、查询扩展技术、资源聚类方式以及本体数量等5个角度对现有方法进行综述。然后,选择10种典型语义搜索方法进行分析比较,总结P2P语义搜索的主要特征。最后,指出下一步研究应探索新的资源组织与搜索机制,并着重关注P2P语义搜索性能评价、查询扩展技术完善、搜索结果排序等方面。A considerable amount of P2P semantic search approaches has been developed. First, the paper introduced a survey schema to review these semantic research approaches from five dimensions, i. e. semantic description method, semantic overlay network structure, query expansion technology, the way of resources clustering and ontology number. Then, the paper compared ten selected typical semantic search approaches by means of the schema. Based on this comparison,we identified and summarized outstanding features of P2P semantic search. Finally, the paper pointed out the necessity to explore new mechanism for resource organization and search,and to focus on a number of open problems, such as P2P semantic search performance evaluation, query expansion technologies improvement and search results ranking.
