Research and improvement of HITS algorithm based on Web link analysis
YU Jinpin · Computer Engineering and Applications Journal · 2013
Vertical search engines have two kinds of subject search strategy, one is based on content evaluation, the other is based on Web link analysis, and HITS algorithm is a classical search strategy that is based on Web link analysis. Its significant drawback is easy to engender topic drift. In order to avoid engendering topic drift in the maximal degree, this paper puts forward a modified F-HITS algorithm that combines Web's text analysis with diffusion rate. Experiment's results show that those improvements not only can decrease system spending but also raise the accuracy of Web page searching.
