Construction of a Personal Knowledge Graph in a Digital Semantic Library LibMeta

The paper discusses an approach to constructing a personal knowledge graph based on an ontological description of a scientific subject area and its data, presented in the form of a knowledge graph. The presentation is based on concepts related to information and data mining, such as subject domain ontology, scientific subject area, thesaurus, semantic digital library, personal knowledge graph. The procedure for constructing a personal knowledge graph is presented using the example of the mathematics subject area, the ontology of which is based on extensive material from the mathematical encyclopedia edited by academician I.M. Vinogradov within the framework of the semantic library LibMeta. The proposed approach will make it possible to use the content of the Mathematics semantic library for scientific research, minimizing the process of searching for information in the local subject area, without losing more general results contained outside this area. This work refers to the experience of building semantic libraries based on thesauruses and ontological design. Construction of ontologies based on the thesaurus of the subject area is a necessary condition for constructing a personal knowledge graph of the scientific subject area.
