Abstract: In recent years, as interest in discriminant analysis of big data has increased, research on this field is active. The use of Big Data is also essential for politics and social issues that are sensitive to public opinion. Classifying precisely which respondents belong to which group is very helpful for policy formulation. Kim et al. (2013) propose an intelligent Voice of customer(VOC) analyzing system based on opinion mining to discriminant the unstructured VOC data automatically and determine the polarity as well as the type of VOC. In this paper, based on the previous studies, we selected the variables that can minimize the discrimination error by using the nearest neighbor method to the discriminant analysis of the formalized data.
