METHOD FOR AUTOMATED ANALYSIS OF TEXT DOCUMENTS Russian patent published in 2013 - IPC G06F17/00 

FIELD: information technology.

SUBSTANCE: all electronic files of reference documents are first converted to a predetermined format while selecting in each document comprehensible fragments referred to as clauses, and the converted electronic files of reference documents are stored in a database. Each electronic file of an analysed document is converted to a predetermined format. A match between the selected clauses in the electronic file of the analysed document and the selected clauses in the electronic files of the reference documents is detected. The relative number of clauses in the electronic file of the analysed document matching corresponding clauses of each of the electronic files of the reference documents is counted. The relative number of matches found is then compared with a predetermined threshold value in order to determine presence of text excerpts of any of the reference documents in the electronic file of the analysed document.

EFFECT: wider range of apparatus by designing a relatively fast and universal method which enables to detect expressions, phrases or even text excerpts in a document from other documents.
