Web document searching using enhanced hyperlink semantics based on XML

We present a system that aims at increasing the flexibility and accuracy of information retrieval tasks in the World Wide Web. The system offers extended searching capabilities by enriching information related to hyperlinks between documents. It offers to document authors the ability to attach additional information to hyperlinks and also provides suggestions on the information to be attached. In an effort to increase the integrity of hyperlink information, a conversion module extracts, from the pages, metadata concerning the linked documents as well as the link itself. The hyperlink metadata is appended to the original document metadata and an XML document is created. Another module allows the end users to query the XML-document base, taking advantage of the enhanced hyperlink information. We present an overview of the system and the solutions it provides in problems found to similar approaches.
