CREATION METHOD OF TRAINING DATA OF QUESTION ANSWERING SYSTEM AND TRAINING METHOD OF QUESTION ANSWERING SYSTEM

摘要

To efficiently create training data for training a summarization system so as to briefly and properly summarize summarization text.SOLUTION: A method includes: a step which extracts groups each including a plurality of relation expressions 240, 242, 244, from abundant causal relation expressions; a step which creates question sentences 280, 290, 300 and answer sentences 282, 292, 302 from each of the relation expressions 240, 242, 244 included in each group; a step which creates a sentence 246 obtained by coupling the relation expressions 240, 242, 246 included in each group; and a step which creates training data items 260, 262, 264 which sets the question sentences 280, 290, 292 created from each relation expressions 240, 242, 246 of each group as an input sentence, the sentence 246 as summarization object sentences 284, 286, 288, and the answer sentences 282, 292, 302 as teacher data, respectively.SELECTED DRAWING: Figure 6
