It is established that the frequency distribution of bigrams in the scientific works of the Russian language is an identifier for the cipher of a specialty. Scientific works, abstracts of various scientists written in Russian were taken. Abstracts were taken in the following scientific fields: History, Pedagogy, Political Science, Philology and Economics. The possibilities of the classifier Z.D.Usmanov to recognize the code of the specialty of the text by the frequency of letter bigrams are investigated. A digital portrait and metric space of scientific works are designed. Assuming uniqueness of the specialty code, threshold metric values \u200b\u200bare established, on the basis of which classes of \u201chomogeneous\u201d scientific works are determined. The \u03b3-classifier of discrete random variables, which has confirmed high efficiency in identifying authorship of text fragments in works of classical and modern poetry, as well as in modern Tajik prose, is tested for adaptability to recognizing the specialty code in the scientific works of scientists.<\/em><\/p>\n\n\n\n
