GENERATION DEVICE, GENERATION METHOD, AND GENERATION PROGRAM

A generation device stores behavior information in which, for each of factors in a factor group, the factor is associated with a behavior taken when the factor is applicable. The processor executes an acquisition process of acquiring, for each of samples, a predicted probability based on whether or not each factor in the factor group is applicable and an importance level of each factor in the factor group which level is the basis for the predicted probability. An extraction process extracts a specific factor from the factor group on the basis of importance the levels obtained by the acquisition process, and a generation process acquires a specific behavior corresponding to the specific factor extracted by the extraction process, from the behavior information, and generates annotation information that presents the specific behavior to each sample to which the specific factor is applicable.
