Method of heterogeneous information resources structuring and systematizing for Internet portals development

The article presents the method of heterogeneous information available on Internet portal structuring and systematizing. In this paper we would like to present methodology for ontology-based development of knowledge Internet portals providing the content-based access to knowledge and information resources as well as to discuss an experience of exploitation of this methodology, problems that arise in the process of its application and way of its solutions. It is proposed to develop specific method of heterogeneous information resources structuring and systematizing while designing knowledge Internet portals in appropriate subject field. Such method is devoted to the next task solving: qualitative knowledge representation; information systematization and structuring; formalization of knowledge based on mathematical models (for chosen subject field); content-based search.
