Parts of speech sequences analysis and the category of idiostyle

The article addresses the linguistic approach to the analysis of the author’s idiostyle, which takes into account the morphological features of texts and the parts of speech sequences presented therein. The author outlines the purpose of analyzing the parts of speech sequences in the context of determining the individual author’s style. He also reveals specific problems related to such analysis - multiplicity of linguistic concepts, variability of the analysis depth, and specificity of the selection of texts and methods for their analysis. The paper describes the Statistical Methods of Literary Text Analysis (SMALT) information system, which can be used, inter alia, for the morphological analysis of publicistic texts, substantiates the usage of a mathematical method for constructing decision trees, and provides the results of the research. The author gives particular examples of the parts of speech combinations that distinguish texts written by different authors. Eventually the conclusion is made about the impact of the text morphological structure on its perception by readers, as well as about the importance of analyzing the parts of speech sequences for determining the author’s idiostyle.
