PARAMETER LEARNING APPARATUS FOR QUASI-SYNONYMY SCALE, PROGRAM THEREFOR, AND QUASI-SYNONYMY SCALE CALCULATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a parameter learning apparatus for a quasi-synonymy scale that can reduce cost for creating correct answer data, and learns parameters enabling calculation of a quasi-synonymy scale of high accuracy.SOLUTION: A quasi-synonymy scale learning apparatus 100 comprises: a correct answer data creation device 1 that creates a quasi-synonymous relation word pair list and a non-quasi-synonymous relation word pair list as correct answer data using a bilingual corpus; a parameter learning device 3 that learns parameters for calculating a quasi-synonymy scale between words using the quasi-synonymous relation word pair list and the non-quasi-synonymous relation word pair list created by the correct answer data creation device 1; and a quasi-synonymy scale calculation device 5 that calculates a quasi-synonymy scale using the parameters learned by the parameter learning device 3.
