基于PageRank的主题过滤算法改进

Filtering Algorithm Based on the Topic of Improving PageRank

对通用搜索引擎中的PageRank排序算法进行分析,针对原PageRank算法中"主题漂移"问题,提出一种与主题相关的改进算法,改进的PageRank值由链接重要性和内容重要性共同确定。

To Analysis of the general search engine ranking algorithm PageRank , the original PageRank algorithm have the ＂topic drift＂ problem,an improved algorithm with the subject which PageRank value the importance of the link together to determine the importance and content have been proposed.
