DEVICE AND METHOD FOR PROVIDING CPC BASED TECHNOLOGY CLASSIFICATION OF PATENT DOCUMENT USING MACHINE LEARNING

摘要

A patent document automatic classification device using machine learning is provided, and a transaction is constructed by extracting the contents contained in at least one identification item corresponding to each of the extraction ranges set in the similar patent classification and classification schema classification from the classification target patent document, , a text mining module that extracts keywords in a transaction through text mining, a classification schema index, CPC class unit index, and publication unit index database for similar patent classification and classification schema classification, and cloud notes composed of characteristic words for each CPC classification code A comparison target having a preset minimum matching rate with the extracted keyword by giving a preset keyword weight to each field including the database engine and the extracted keyword, and giving a preset field weight to each comparison target in the database engine is included in the similar candidate group, the similarity of the comparison target included in the similar candidate group is calculated based on the vector space model, and the degree of similarity is determined through ranking correction using additional information for the CPC classification code in the comparison target. It includes a similarity measurement module that sorts and outputs in high order.
