Data classification system, data classification method, and data classification device

摘要

To efficiently generate a classifier in an integrated classifier and allow improvement of classification accuracy.SOLUTION: A data classification system 100 includes: a device 102 which integrates classification results of a prescribed dataset obtained by a plurality of classifiers respectively and stores correspondence between a feature quantity of the dataset and a label being the classification results, as learning data; and a device 103 which performs processing of calculating a non-simultaneous classification probability that a plurality of labels may be not classified for one dataset and a simultaneous classification probability that a plurality of labels may be classified for one dataset, with respect to each of unlabeled datasets in the learning data on the basis of the feature quantity and a classification probability outputted from an integrated classifier which has learnt from the classification results of the respective classifiers, processing of aggregating multiplication values between the non-simultaneous classification probability and the simultaneous classification probability for each label to calculate a recommendation score, and processing of specifying labels in the descending order of recommendation score as labels for which classifiers should be additionally generated, to output the labels as recommendation information.SELECTED DRAWING: Figure 1
