Komarnytska O. Models and methods of the text linguistic analysis of the intellectual knowledge evaluation system

A functional structure of an intellectual system of linguistic analysis of a deployed text response utilizing models of artificial intelligence has been developed and tested in this research paper. An algorithm of fuzzy semantic comparison of textual information - answers to questions submitted by a student in natural language, with options of correct answers, which formalizes description of linguistic structure of the study content and answers has been elaborated for the first time. The algorithm provides automatic conversion of student's responses from a natural language into an intersystem form, the formation of lexical units of the text, followed by the implementation of morphologic, syntactic, semantic and pragmatic analysis. In order to form a frequency matrix of the indexed words there has been improved the algorithm of latent-semantic analysis of textual information.
