Ontology-based approach to development of adjustable knowledge internet portal for support of research activitiy

This paper presents an approach to the development of specialized Internet portals providing content-based access to systematized knowledge and information resources, relating to a certain branch of science. The information basis of such portals is formed by ontologies, containing the description of scientific and research activity as a whole as well as description of some branch of science, and descriptions of the Internet resources which are relevant to ontologies of the portal. The operation of such a portal is based on a multi-agent system which uses the ontologies and supports both a search for the necessary information in the information space of the portal and automatic update of the portal’s content with new knowledge and information resources.
