一种改进的PageRank算法
An Improved PageRank Algorithm
摘要
Abstract
Aiming at the problems of Topic-drift and emphasizing on old web pages for PageRank algorithm, combined with anchor texts similarity and timing feedback factor, this article presents an improved algorithm STPR, and analyzs STPR algorithm by experiment. First this article compares the traditional PageRank algorithm and adding anchor text similarity PageRank algorithm, results show that by adding anchor text similarity PageRank algorithm helps to reduce the occurrence of the phenomenon of topic-drift. Second this article compares adding anchor text similarity PageRank algorithm and STPR algorithm, results show that STPR algorithm not only reduce topic-drift phenomenon, but also make up PageRank value for new web pages.关键词
