| 摘 要： | 针对传统数字图书馆中基于关键字的P2P查询扩展存在对用户检索词语义信息解释不足的缺陷，本文提出一种P2P环境下基于语义的节点查询扩展方法，通过把关键字关联表和本体相结合，实现了一种个性化查询扩展方法，同时利用这种扩展方法实现P2P中基于兴趣网络的搜索，能够较大幅度提升检索效率。

| Abstract: | As to traditional keyword - based P2P query expansion in Digital Lihrmy of user retrieval lacking of semantic infonnation which can hardly explain the query, this paper proposed a P2P environment based on semantic node query expansion methods, through the combination of keyword association table and the ontology, to achieve a personalized query expansion methods, while the use of this extension method based on interested in network search, could greatly enhance the efficiency of P2P retrieval. |
