A representative feature quantity calculation unit () determines a representative feature quantity for each facial expression label from the face image of the desired group. The target data extraction unit () extracts target data from a facial expression data set. A target feature quantity calculation unit () calculates a target feature quantity from the target data. A corrected label determination unit () determines a corrected label to be assigned to the target data by comparing the target feature quantity and each of the representative feature quantities. The label assignment unit () assigns a corrected label to the target data.
