Technology for building ontologies for an information system to support scientific and educational activities

Abstract

The article presents an approach to organizing scientific portals based on ontologies. Ontology is the information basis of the Internet portal of knowledge, which should provide integration and systematization of scientific knowledge and information resources of a certain subject, as well as meaningful access to them from any "point" of Internet space. The ontology automatically builds a diagram of the portal's internal database and forms for filling it out, organizes navigation through the portal's information space, and ensures that search queries are formulated in terms of the knowledge portal's subject area. The division of the portal's ontology into subject-independent and subject-specific ontologies makes the portal customizable for almost any field of scientific knowledge. This technology allows declarative adjustment of the ontology during the operation of the knowledge portal, which allows you to track the dynamics of the emergence of new knowledge and information resources on the subject of the portal and thus provides support for its relevance and usefulness.
