Abstract :
The main focus of this paper is the query and search facilities in the XHMG system. The XHMG system allows modeling, integration, search, and retrieval of Web multimedia data (hypermedia) from heterogeneous data sources based on its content and semantics. The paper shows the basic XHMG structural instruments for Web and Web page content extraction and representation. The emphasis in the paper is showing the visual query mechanisms which allow search and retrieval of collection of Web-based documents (pages, data, multimedia) based on their Web document metadata, intra-document metadata, inter-document metadata, or in short-based on their content. The main application of this approach is handling, integrating, and searching the multimedia information in the Web based on its content and meaning. The research in the paper can have an impact on the e-technologies.
