Ontological Basis of Knowledge Management in the Context of Educational and Research Activity

Abstract

The main problem in organizing the transfer of knowledge in scientific and educational activities is to extract it from data and information, as well as to effectively present it to the end user in a form that is convenient for perception. The exponential growth of the volumes of information and data and their accumulation in spatially distributed databases and repositories has created the need to use new methods and tools that allow to significantly increase the efficiency of the processes of extraction and transformation into knowledge. At the same time, the main goal is to ensure high quality of educational and scientific materials, which, in turn, depends on the volumes of information sources processed by teachers and researchers. Simultaneously, the problem is the fragmentation and dispersion of information, which significantly complicates its holistic perception. The solution is the application of ontological models, as one of the most modern techniques of knowledge representation. Therefore, it is quite appropriate to use ontological and ontology-controlled approaches in the processes of knowledge transfer. An option of the implementation of such an approach based on cognitive services that implement the processes of creating annotations, extracting named entities, generalizing terms, determining the semantic proximity of terms, categoriz­ing and classifying terms, and full-text search is proposed. As a result, a high level of efficiency in the presentation of educational and scientific materials is achieved for their successful use and perception.
