document: A comparison of implicit and explicit links for web page classification It is well known that Web-page classification can be enhanced by using hyperlinks that provide linkages between Web pages . However , in the Web space , hyperlinks are usually sparse , noisy and thus in many situations can only provide limited help in classification . In this paper , we extend the concept of linkages from explicit hyperlinks to implicit links built between Web pages . By observing that people who search the Web with the same queries often click on different , but related documents together , we draw implicit links between Web pages that are clicked after the same queries . Those pages are implicitly linked . We provide an approach for automatically building the implicit links between Web pages using Web query logs , together with a thorough comparison between the uses of implicit and explicit links in Web page classification . Our experimental results on a large dataset confirm that the use of the implicit links is better than using explicit links in classification performance , with an increase of more than 10.5 % in terms of the Macro-F1 measurement .
