Study of Qualitative Data Cluster Model based on Granular Computing

Granular computing theories in the field of computer are introduced into the statistical analysis of qualitative data, based on the traditional qualitative data analysis methods. Multidimensional qualitative data by use of information system are described, and the mathematical model of qualitative data cluster model based on granular computing is given. The feasibility and the superiority are verified by treating massive data. This method may provide a new train of thought for analysis of large and complex qualitative data.
