Sentence classification device, sentence classification method and sentence classification program

摘要

PROBLEM TO BE SOLVED: To provide a sentence classification device, a sentence classification method and a sentence classification program capable of appropriately classifying sentences by adjusting parameters. SOLUTION: A case sentence acquisition unit for acquiring a plurality of case sentences associated with an effect value which is a value for evaluating an effect, and a case value for generating a case value obtained by digitizing the case sentence for each parameter having a different value. A parameter is selected from a generation unit, a correlation coefficient calculation unit that calculates the correlation coefficient between the case value and the effect value for each value of the parameter, and a parameter having a different value based on the correlation coefficient. It is characterized by including a parameter selection unit. [Selection diagram] FIG. 8
