Title: INFORMATION PROCESSING DEVICE, METHOD, AND PROGRAM
Abstract:
The present invention addresses the problem of more accurately determining whether or not new target data is unknown classification target data. An information processing device 1 is provided with: a feature extraction unit 23 that generates feature data by extracting features from new target data; a clustering unit 25 that clusters a set of target data comprising classified target data and the new target data into clusters the number of which is a number obtained by adding one to the number of classifications to which the classified target data have been classified, on the basis of feature data of the classified target data and the feature data of the new target data generated by the feature extraction unit 23; and an inquiry output unit 28 that outputs an inquiry for inquiring about the classification of the new target data in the case where a cluster including only the new target data has appeared as the result of the clustering.
