Approach to Creating a Thesaurus and a Knowledge Graph of an Applied Subject Area

An ontological approach to the construction of a thesaurus of the applied subject area of a scientific academic journal based on the content of the LibMeta semantic digital library and subject area sources is considered. A thesaurus and a knowledge graph of the subject area of scientific publications of the journal of the Russian Academy of Sciences Mechanics of Composite Materials and Structures , devoted to the modeling of composite materials and structures, is being built. The approach is based on the use of the content of the semantic library LibMeta, classical primary sources on the theory of elasticity and metadata of the journal articles. As a result, a thesaurus and a knowledge graph of the subject area of the journal are built, and on their basis the user interface is modified and a variant of navigation through the links of articles is proposed. Examples of constructions are given.
