Popis: The article examines the problems of searching various formal models that are able to reflect fragments of the surrounding reality as structures of consciousness of speakers of a certain language. Graphs were established to be the most suitable for formalizing knowledge about fragments of existence among such models. The construction of graphs reproduces the relationship between the components of these fragments. The author made an excursion into the theory of graphs, characterized their typology and revealed possibilities of using graphs in linguistic studies, in particular for the formalization of elements of the phonological, morphological, syntactic and lexico-semantic language levels.The developed methodical algorithm for constructing a graph of the lexico-semantic field of the pandemic using the Gephi computer programme helped to visualize the structure of the lexico-semantic field and the relationship between its core and periphery, as well as to measure the degree of semantic density of the elements of the lexico-semantic field. The research showed the following advantages of the selected computer programme: support for the Windows operating system; simplicity and user friendliness; possibility to upload the necessary document to the system (CSV file), which facilitates the user’s work, because it is not necessary to manually enter data about vertices and edges into the programme; preview of the constructed graph and editing of its elements; saving in a special format for further display of the interactive graph on the Internet. The selected programme was used to construct a complex undirected lexico-semantic graph with a vertex pandemic.
