DEVICE FOR COLLECTING CONTRADICTORY EXPRESSION AND COMPUTER PROGRAM FOR SAME

摘要

(Problem) Provides a device capable of efficiently collecting contradictory expressions in units smaller than sentences. (Solution) The apparatus for collecting contradiction expresses a pattern by using a pair of patterns consisting of a pattern of a pattern of " X is Y " An additional contradiction pattern pair deriving unit 130 for deriving a new pattern pair by applying one or more patterns to each of the extracted pattern pairs to derive a new pattern pair; A learning data expanding section 136 for expanding learning data by adding a pair of patterns highly likely to be formed with contradictory patterns to learning data and a learning data expanding section 136 for expanding learning data by adding a pattern pair given by machine learning using extended learning data And an SVM 142 for performing a second-stage classification for classifying the pattern pairs and the other.
