Problem statement. Formation of a single space of scientific knowledge, integration of disparate sources of information in the field of mathematical knowledge. Objective. Building a knowledge graph of a collection of mathematical equations. Results. A method for constructing a knowledge graph of mathematical equations based on information from the scientific and educational portal EqWorld "World of Mathematical Equations" and the ontology of professional mathematics OntoMathPRO is proposed. A set of software services and tools has been developed that ensure the formation of a knowledge graph of mathematical equations and its storage in a data warehouse with the ability to perform SPARQL queries. The developed software services were tested, and the accuracy of linking entities presented on the EqWorld portal to ontology concepts was evaluated. Practical significance. The mathematical equation knowledge graph is included as a mathematical artifact in the OntoMath digital ecosystem of the Lobachevskii-DML digital mathematical library. Semantic services of the specified ecosystem are being designed based on this knowledge graph.
