XHMG: Content-Based Web HyperMedia Modeling and Retrieval System

Many studies concentrate on developing attractive Web applications, but very few discuss the fundamental problems of modeling, integration and retrieval of Web hypermedia data from heterogeneous data sources based on its content and semantics. The main focus of this paper is the modeling facilities in the XHMG system for content-based representation, integration and retrieval of heterogeneous Web data. The paper shows the basic XHMG structural instruments for Web and Web page content representation. The most important application of this approach is handling and integrating the hypermedia information in the Web based on its content and meaning. The research in this paper will have a potentially large impact on the technologies used in information sources for e-business, e-advertising, e-commerce, e-government, e-learning, portals, digital libraries, Web search engines, online catalogs.
