Title:
DATA EXTRACTION DEVICE, DATA EXTRACTION METHOD, AND DATA EXTRACTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/199170
Kind Code:
A1
Abstract:
This data extraction device is provided with: a parameter analysis unit (1) for performing morpheme analysis on learning text information, extracting words to be served as machine learning parameters, and classifying the words according to each type of the parameters; a classification setting display unit (2) for determining, on the basis of the parameters, data to be searched and a clustering condition; one or more clustering learning data extraction units (3) for extracting learning data from a database on the basis of the data to be searched and the clustering condition; one or more clustering units (4) for executing clustering process based on the clustering condition in a learning mode by using the learning data; an applied clustering determination unit (5) for performing morpheme analysis on searching text information and specifying the data to be searched, which is used as a narrowing-down condition, and an executing clustering unit (4); and a search range specification unit (6) for causing the clustering unit (4) to execute the clustering process and extracting, on the basis of an executed result, the learning data from the database by narrowing down the range of the data to be searched.
