Abstract: For the topic drift and bias towards the old pages of WPR(Weighted PageRank) algorithm exist in the Web search,consolidated two factors of Web pages’ topic features and referenced frequency in recent search cycle,we proposed an improved algorithm WTFPR(Weighted Topic Frequency PageRank).The algorithm uses improved TD-IDF algorithm to solve relevance of page by content analysis to reduce the topic drift. The algorithm improves the PR value of new and has high quality by referenced frequency of pages in recent search cycle,reducing bias towards the old pages.Simulation results show that the improved algorithm obtaines better results compared to WPR.

Key words: Topic features,Referenced frequency,Bias towards the old pages,Search cycle,Topic drift
