PROBLEM TO BE SOLVED: To actualize a method and a device which provides a high-precision resolution without requiring a large amount corpuses and which performs high- precision cost determination without manual intervention. SOLUTION: A morpheme analysis of an input sentence is performed (step S1). Word divisions of the morpheme analysis result are compared with word divisions of the correct answer of a previously provided corpus (step S3), and when they do not match each other, a sample is generated which shows differences between the feature vectors of the morpheme analysis result and the feature vectors of the corpus (step S5). As for samples which are generated so far, the value of a weighted vector is calculated from the value of the reverse matrix of the variance/covariance matrix of the sample and the mean transposed matrix of the sample (step S6). |
