Abstract: Differences in the structure of Web pages and text make traditional IR methods not meet development of Web. In order to rank results properly, link analysis is introduced into results analysis, which based on academic citation analysis. It gives high evaluation to pages having many back links. Meantime, similarity between anchor text and query is paid attention to. The qualities of source pages vary much and anchor texts from different source pages also differentiate. But maybe anchor text from low quality source pages is more precious than those from high ones. This paper amends the anchor text having large similarity. That is: calculating the similarity between anchor texts and query and amending those anchor text of high similarity from source web pages with low Page Rank. And then use the new value to rank web pages again.
