消费者健康信息门户网站的主题导航优化研究

摘要

This paper proposes a method to detect the correlation between resources based on semantic calculation and link analysis .NICHD site is selected as a test case, by which we have verified the feasibility of the topic navigation optimization method proposed in this paper. The results show that this navigation optimization method based on semantic similarity calculation and link analysis is superior to the traditional method that dependents on content clustering to optimize navigation. Also it can aggregate related resources to the most extent, reduce the search time and improve the user experience.%本文在综合归纳健康信息门户网站主题网页的内容与链接特性的基础上，提出了一种基于语义计算与链接分析相结合的方法来探测资源间的关联性，并选取NICHD网站作为实验案例，验证了文中提出的主题导航优化方法的可行性。实验表明：基于语义相似度计算与链接分析相结合的导航优化方法一定程度地优胜于传统的依赖内容聚类优化导航的方法，且能够最大程度地将相关资源汇聚，缩短了检索时间、提升了用户体验。
