The study is based on the corpus of texts of Russian classical prose of the XIX century. It is shown, how by means of the comparative statistical analysis of creativity of different authors it is possible to reveal the specificity of individual style. By the example of the specific cases of use of the word "лицо" (in English, "a face") in Anton P. Chekhov’s work are presented features of psychological narration. The conclusions about the interdisciplinary perspectives of the corpus methodology were made.This study was funded by the Russian Foundation for Basic Research Grant № 19‑12‑0104
