Decai Huang, Huachun Qi, Yuan Yuan, Yue-feng Zheng · 2006
PageRank algorithm is a famous algorithm to mine the Web structure, but it has a drawback of topic-drift. To eliminate the topic-drift of the PageRank algorithm, and after the analysis of existing algorithms, a new algorithm called TC-PageRank algorithm is put forward. The TC-PageRank algorithm is based on fictitious file vector and correlation measure of cosine. Experimental results illustrate that TC-PageRank algorithm eliminates the topic-drift phenomenon effectively, and thus improves the quality of retrieving
