Exploiting Web Sites Structural and Content Features for Web Pages Clustering

摘要

Web page clustering is a focal task in Web Mining to organize the content of websites, understanding their structure and discovering interactions among web pages. It is a tricky task since web pages have multiple dimension based on textual, hyperlink and HTML formatting (i.e. HTML tags and visual) properties. Existing algorithms use this information almost independently, mainly because it is difficult to combine them. This paper makes a contribution on clustering of web pages in a website by taking into account a distributional representation that combines all these features into a single vector space. The approach first crawls the website by using web pages' HTML formatting and web lists in order to identify and represent the hyperlink structure by means of an adapted skip-gram model. Then, this hyperlink structure and the textual information are fused into a single vector space representation. The obtained representation is used to cluster websites using simultaneously their hyperlink structure and textual information. Experiments on real websites show that the proposed method improves clustering results.
