Domain-oriented information search on the Internet


The article is devoted to the study of the problem of information search on the Internet by using knowledge about the domains of the Web space. The domain information model (IM), the virtual Web environment model (VWE) and the user query model (UQ) are proposed, as well as the relationships and mapping principles between them are investigated. The possibility of providing a thematic focus, improving the quality and efficiency of the search process, improving results using an information model of domain representation is considered. Based on this model, a domain-oriented information search system for the Internet Web space has been developed. To improve the quality of the search engine and search results, a fuzzy logic approach is used, thanks to which a fuzzy domain-oriented information model of the Web space is proposed. Within the framework of the proposed models, methods have been developed for determining the content connectivity of Web documents, dividing the Web space into related Web areas, and virtual unification of Web areas.
