FIELD: physics.
SUBSTANCE: invention relates to artificial intelligence. System for automatic determination of subject matter of text documents based on explicable artificial intelligence methods comprises a set of interconnected modules interacting by exchanging synchronizing signals through inputs and outputs. Modules used are: a module for preliminary processing of input data, a linguistic analysis module, a module for evaluating the significance of words and phrases, a module for determining a subject, comprising a representation of a hierarchy of headings, a module for explaining the heading result, which, having obtained the results of assigning the classified document to a certain subset of headings, as well as significant features of the text, generates an description in the form of string representations of words and phrases and their significance, training process control module, which implements the system training process stages, a module for controlling the rubrication process, which implements the stages of the process of determining compliance of the subject of the text of the incoming documents with the categories of the rubricator.
EFFECT: providing high accuracy, completeness and level of reliability of results of automatic heading.
