Improving Web usability by categorizing information

Modern browsers allow users to search and navigate the vast amount of Web data, but the significant problem of extracting desired information from such data still remains, mainly due to the lack of an explicit structure both in Web pages and sites. We present an approach to Web structuring in which both Web pages and sites are considered. In particular, we analyze the structure and semantics, aiming at highlight (possibly hidden) structural and semantic organization, therefore building an explicit logical schema, which improves Web usability (browsing, searching) and designing.
