METHOD AND SYSTEM FOR OBTAINING VECTOR REPRESENTATION OF ELECTRONIC TEXT DOCUMENT FOR CLASSIFICATION BY CATEGORIES OF CONFIDENTIAL INFORMATION Russian patent published in 2022 - IPC G06F16/35 G06F40/284 G06F40/30 

FIELD: computer technology.

SUBSTANCE: invention relates to computer technology. A computer-implemented method for vector representation of an electronic text document for determining the category of confidential information contained in it, performed using a processor and containing the steps, at which: a model for placing m-skip-n-grams in clusters is formed, while forming the said model: determining the list of used m-skip-n-grams; converting to a vector representation of each m-skip-n-gram from the list; m-skip-n-gram clustering; perform processing of the text document using the obtained model, during which: the occurrence of m-skip-n-grams in the document is counted; determining document clusters based on the occurrence of m-skip-n-grams; the number of occurrences of m-skip-n-grams from each cluster is summarized; a vector representation of the document is formed; the category of confidential information in a text document is defined.

EFFECT: enabling the preservation of different semantics of words in a document by mapping words to multiple clusters.
