METHOD AND SYSTEM FOR CLASSIFYING DATA FOR IDENTIFYING CONFIDENTIAL INFORMATION IN THE TEXT Russian patent published in 2021 - IPC G06F21/60 G06F40/279 G06N20/00 

FIELD: computer technology.

SUBSTANCE: invention relates to the field of computer technology for identifying confidential information. A computer-implemented method contains stages in which: data presented in a text format is obtained; obtained data is processed using machine learning algorithms, during which each word in a text is assigned with a tag corresponding to a given type of confidential information, wherein a classification matrix is formed for each machine learning algorithm, based on which an F-measure is calculated for each data type; the classification of each word in the text is performed based on texts with tags received from each machine learning algorithm and the F-measure matrix corresponding to machine learning algorithms, and the final version of the text with tags is formed; the classification of the text with tags attached to each word by privacy classes is performed based on the comparison of the combination of available tags in the text with specified tags of confidential information.

EFFECT: increased accuracy of classification of confidential information.
