CLUSTERING OF DOCUMENTS Russian patent published in 2022 - IPC G06F16/35 

FIELD: physics.

SUBSTANCE: invention relates to computer engineering for analyzing documents. Technical result is achieved by obtaining an input document; determining, by evaluating a document similarity function using one or more calculated attributes of the input document, a plurality of similarity metrics, where each similarity indicator from the plurality of similarity indicators reflects the degree of similarity between the input document and the corresponding cluster of documents from the plurality of document clusters; determining the maximum similarity score from the plurality of similarity indicators; determining that the input document does not belong to any of the document clusters from the plurality of document clusters if the maximum similarity score is below a threshold value; creating a new cluster of documents; and assigning an input document to a new cluster of documents.

EFFECT: high accuracy of clustering documents.
