Being a good entry page to a Web site reflects how well the page enables a user to obtain optimal access, by browsing, to relevant and quality pages within the site. Our aim is to model a measure of how good an entry page is, as a combination of evidence of the properties exhibited by the Web pages, which belong to the same site and are structurally related to it. The proposed model is formally expressed within DempsterShafer’s Theory of Evidence and can be applied in the context of Web Information Retrieval tasks.
