Title:
QUESTION ANSWERING SYSTEM TRAINING DEVICE AND COMPUTER PROGRAM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/038657
Kind Code:
A1
Abstract:
[Problem] To provide a training device for a why-type question answering system with which learning data for a classifier is created efficiently while limiting manual intervention as much as possible. [Solution] A training device 62 includes: a question issuing unit 100, which issues to a question answering system 60 a question stored in a question/predicted answer storage unit 76; an answer candidate filtering unit 102, an answer candidate assessment unit 104, a learning data generation/labeling unit 106, and a learning data selection unit 108, which generate and add to a learning data storage unit 64 learning data for a ranking unit 122 of the why-type question answering system 60, said learning data being generated from pairs comprising the question and each of multiple answer candidates output together with a score from the question answering system 60; and an iteration control unit 110, which controls the question issuing unit 100, the answer candidate filtering unit 102, the answer candidate assessment unit 104, the learning data generation/labeling unit 106, and the learning data selection unit 108 so as to repeat the learning by the learning device, the issuing of a question, and the addition of the learning data, until an end condition is fulfilled.
