摘要

PROBLEM TO BE SOLVED: To provide a sentence classification learning device capable of accurately estimating a classification of a sentence, a sentence classification device, a sentence classification learning method and a sentence classification learning program.;SOLUTION: The sentence classification learning device generates series data having an identity of each sentence as an element for each of a plurality of pieces of learning data on the basis of a plurality of pieces of learning data indicating an object sentence with a classification label attached and reference sentences before and after the object sentence with clue labels attached, a classification label set defining each classification label and a clue label set defining each clue label, calculates the importance of each sentence on the basis of clue labels attached to the reference sentences and the identity of each sentence concerning each of the plurality of pieces of learning data, and learns a classification label estimation model on the basis of the importance of each sentence, the classification label attached to the object sentence and the series data concerning each of the plurality of pieces of learning data.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
