The use of knowledge graphs in the educational environment for personalized learning

Abstract

The article presents some methods for creating knowledge graphs – hierarchical structures used in the educational environment for course development. It is found that the educational environment requires subject-oriented knowledge graphs, for the creation of which the methods of creating general and open graphs are not suitable. The methods of constructing the system of notions of educational discipline on the basis of: analysis of educational texts; human activity in the studied subject area; analysis of the structure of the main sections of knowledge are considered. The central aspect of the study was the possibility of using the resulting tree of concepts to form the content of the training course and to build an individual educational trajectory. The results of the work demonstrate the possibility of applying the developed hierarchical structures to personalize learning. The practical significance of the obtained results lies in the fact that the proposed solutions are focused on computer implementation and are relevant for the management of the learner’s learning activities in the electronic environment. The proposed methodology involves the participation of professional and scientific communities, teachers and students in the development of the knowledge graph. This makes it possible to develop subsequently, on the basis of these graphs, training programs, taking into account the demands of the labor market, the capabilities of the training organization, as well as the goals of trainees. One important indicator of the quality of knowledge graphs is their relevance to a dynamically changing environment. The ability to build up knowledge graphs allows to maintain the relevance of training courses and individual educational trajectories created on their basis.
