Conceptual modeling of texts of the Tuvan language using methods of formal concept analysis
One of the important components of the ethnocultural heritage of the Republic of Tuva is the analysis of the texts of Tuvan heroic epics. In the scientific database of the Tuva Institute for humanitarian and Applied socio-economic research of the Republic of Tyva tape and handwritten recordings of all genres of Tuvan folklore are stored, including in old dilapidated editions of about 300 Tuvan heroic epics. Nowadays, the electronic database "Tuva heroic epics" has been created by teachers and students of Tuva State University. This collection is embedded in the electronic corpus of the Tuvan language. This collection contains digitized texts of Tuvan heroic epic, their meta-descriptions and information about the storytellers. Using this electronic collection, it is possible to solve linguistic and philological problems, which are reduced to the problem of conceptual modeling of the collection "Tuvan heroic epics". In this article, the task of establishing the author's style of narrators when describing horse equipment in the works of the Tuvan heroic epic is considered. To solve this problem, an algebraic approach is used, which in the literature is called the formal concept analysis. Within the framework of formal concept analysis, the collection " Tuvan heroic epics" is presented as a formal context. Then the solution of the problem is aimed at identifying the set of all formal concepts of the formal context and linking them into a lattice. The resulting lattice serves as a conceptual model and a basis for solving the problem.
