DATA ANALYSIS SYSTEM, DATA ANALYSIS SYSTEM CONTROL METHOD, AND DATA ANALYSIS SYSTEM CONTROL PROGRAM

摘要

Provided is a data analysis system which, by analyzing whether a pattern which is extracted from training data is included in unknown data, evaluates a correlation between the unknown data and a prescribed case, said data analysis system comprising: a data evaluating unit which evaluates a correlation on the basis of the extracted pattern; a reference assessment unit which assesses whether the result of the evaluation satisfies a prescribed reference; a data selection unit which selects a prescribed number of instances of data from the unknown data for which the correlation has been evaluated; a data re-evaluating unit which re-evaluates the correlation between the selected data and the prescribed case on the basis of a pattern which is included in the selected data; and a reference change unit which changes the prescribed reference on the basis of the result of the re-evaluation.
