摘　　要：搜索引擎的相关结果排序技术是信息检索技术发展中的关键问题,也是将来研究的热点问题之一。在分析传统的相关排序方法基础上,介绍了PageRank算法和HITS算法的核心技术,指出了PageRank算法忽视专业站点、对网页中的超链接评估不当之处,根据面向主题的思想,在重新计算链接对网页的影响的基础上,提出了一种新的关于链接技术的排序方法,并通过实验对该算法的性能进行分析评价。The technology of related result sorting in search engine is the key problem during the development of information retrieval technological, and also is one of hot topics which the future will study. In the foundation of analysis tradition correlation arrangement method, the core technology of PageRank algorithm and the HITS algorithm are introduced, and the disadvantage of this algorithm is given, such as neglecting specialized sites, inaccurate judge ofhyperlinks, according to the thought of facing the subject. In the foundationg of recomputing the influence of the link to the web page, one kind of new about the link technology arrangement method based on the thought of facing subject is proposed. And the performance of this algorithm is carried on the analysis appraisal with the experiment.
