This paper studied the effects of using of link information for Web IR in TREC experiment,including link anchor text,link structure and the combination of link-based retrieval and traditional content-based retrieval.Several conclusions are drawn:Firstly,anchor text can represent precisely the topic of Web page,but insufficient in describing the Web page content.Secondly,comparing with traditional content-based IR technique,using link-based approach on homepage finding task can get more than 96% improvement,while it is not helpful on ad hoc task.Finally,combining link-based and content-based techniques makes consistent 48% to 124.8% improvement on homepage finding task and some progress on ad hoc task.
