包含关联的语义覆盖网构建方法研究
发布时间：2018-12-11 05:09
【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。
[Abstract]:There are various relationships between information resources in the real world, but the current search engine can only provide keyword-based search, and can not provide users with all kinds of keyword-related information they care about. In order to solve this problem, a semantic overlay network is proposed, which is oriented to the user's needs, takes the information concerned by the user as the center, and aggregates all the information related to this resource to the user. Firstly, the nodes are clustered according to the semantic similarity, and then, based on the clustering, the semantic overlay network based on the association relation is constructed.
