Abstract

The present invention relates to an information analysis system comprising: a summary table creation unit for analyzing an input file if the file is inputted, extracting a field list corresponding to the field list information stored in a provided database, and creating a summary table including the extracted field list; a preprocessing module for performing a preprocess including at least one of field refinement, group creation, and sub-data set creation, for fields of the summary table created by the summary table creation unit; a matrix creation unit for creating a matrix based on matrix setting information inputted by a user, for the fields created by the summary table creation unit or the preprocessing module; a cluster analysis unit for analyzing a cluster of corresponding fields according to a cluster analysis method inputted by the user, for fields selected by the user among the fields created by the summary table creation unit or the preprocessing module; and a visualization data creation unit for creating visualization data according to a visualization method selected by the user, for data created by at least one of the matrix creation unit, the preprocessing module, and the cluster analysis unit, in which methods such as a matrix, preprocessing, cluster analysis, and the like are allowed to be used in analyzing files so that accuracy and efficiency of information analysis can be enhanced.
