Document Type and Number:
Japanese Patent JP2018180935
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a parallel phrase analysis device, a parallel phrase analysis model learning device, a method, and a program capable of performing parallel phrase analysis of an input sentence with high accuracy.SOLUTION: A parallel phrase candidate extraction unit 222 extracts a plurality of combinations of phrases before and after a coordinate conjunction as a parallel phrase candidate from an input sentence. A language model application unit 226 outputs, for each of the parallel phrase candidates, by using the language model, a prediction result at the time when predicting the word immediately after a phrase before the coordinate conjunction and a prediction result at the time when predicting the word immediately before the phrase after the coordinate conjunction. A ranking calculation unit 230 calculates, for each of the parallel phrase candidates, by using a ranking model, a ranking score to output an analysis result of the parallel phrase, from the prediction result of the word immediately after the phrase before the coordinate conjunction and the prediction result of the word immediately before the phrase after the coordinate conjunction.SELECTED DRAWING: Figure 4
