摘要

PROBLEM TO BE SOLVED: To obtain a class relating to the relationship of a sentence pair in consideration of interpretation of words.SOLUTION: A convolution unit 238 outputs a feature matrix Fobtained by performing convolution processing on a feature matrix Foutput from a word vectorization unit 32, a feature matrix F' output by a sentence pair attention unit 32, and a feature matrix F" output by a word interpretation expanded sentence pair attention section 36, in each layer of a neural net, as an output of a layer i, to each of sentences of the sentence pair. A classification unit 240 classifies each of the sentence pairs included in a set sentence pairs to a class relating to the relationship of the sentence pair on the basis of feature matrices Fand Ffor each of the sentence pair output by a last layer B of the neural net.SELECTED DRAWING: Figure 6
