A Vector Space Projection HITS Algorithm Based on Similarity Value
There usually have several problems,such as low accuracy and data redundancy,in the result set given by the traditional search engine.HITS algorithm based on Web structure mining technology can markedly improve the effectiveness of searching Web pages.Deeply analyzes HITS algorithm and some pertinent improved algorithms,and proposes a vector space projection HITS algorithm.This algorithm,which is based on the analysis of hyperlink structure and combining page text content,can relatively eliminate the theme deviation issue in HITS algorithm without causing extra system overhead.
