DEVICE OF SIMILARITY CALCULATION AND PROGRAM OF SIMILARITY CALCULATION Russian patent published in 2009 - IPC G06F17/30 G06Q10/00 

Abstract RU 2344474 C2

FIELD: information technologies.

SUBSTANCE: device of similarity calculation contains facility of technical documents groups' introduction, which is intended for introduction of the first group of technical documents and the second group of technical documents subject to comparison; facility of technical information introduction intended for introduction of technical information; facility of cluster analysis, which is intended for search of technical documents that are contained in the first group of technical documents and the second group of technical documents and contain introduced technical information, and for breakdown of found technical documents into clusters for every technical information; facility of similarity calculation, which is intended for calculation of ratio of total number of clusters obtained as a result of cluster breakdown, to number of mixed clusters that contain technical documents from the first group of technical documents and from the second group of technical documents; and derivation facility intended for derivation of calculated similarity.

EFFECT: creation of device and method of similarity calculation, which provide for possibility to compare groups of technical documents in wide area, which is not limited by patent publications or similar documents.
