基于时间反馈和分类技术的PageRank改进算法

An improved PageRank algorithm based on time feedback and classification technology

首先对经典排序算法—PageRank算法进行优劣分析,对其缺点提出针对性的改进。在原有算法中融入网页之间的链接相似度,并加入时间反馈因子,最终提出基于时间反馈和分类技术的PageRank搜索引擎改进算法,解决了PageRank算法搜索应用中结果偏向于旧网页的问题,并提高了用户搜索的查准率。

This paper has analyzed the advantages and disadvantages of PageRank algorithm which was one of the classical scheduling algorithms systematically and deeply,and its shortcomings targeted improvements were proposed.Then we introduced the link similarity between webpages and time feedback factor.Finally,an improved PageRank algorithm for search engine,which is based on time feedback and classification technology,was given.It solved the problem of biasing to old webpages when applying the former PageRank algorithm,and the precision of the search result was also improved.
