摘　　要：现实世界中信息资源之间存在着各种各样的关联关系,而当前的搜索引擎只能提供基于关键字的搜索,不能为用户提供他们所关心的与关键字相关的各类信息。针对这个问题,提出了构建语义覆盖网,以用户需求为导向,以用户所关心的信息为中心,将所有与此资源相关的信息全部汇聚起来提供给用户。这里先根据语义相似度将节点聚类,然后在聚类的基础上,根据各类关联关系构建基于关联关系的语义覆盖网。There are kinds of relatedness between the information resource,but the current search method is based on the keywords and can＇t offer the related information that users care about very much.Aiming at this problem,this paper proposes building a semantic overlay network based on association. It takes the information that users concerned as the center,then collects all the related information.At first,these peers should be clustered according to the semantic similarity.Based on these clustering,their assciation is analyzed and semantic overlay networks are built.
