Abstract
A response style component removal device capable of removing a response style that does not depend on content of a questionnaire is provided. The response style component removal device generates a probability of rating values for question items from raters who have rated questionnaires. Specifically, learning data for training the device include rating values for a plurality of question items from a plurality of raters who have rated a plurality of types of questionnaires. The device is configured to learn a rater parameter θthat indicates a tendency of each rater, an item parameter βthat indicates a tendency of each question item, and a response style parameter γ indicates a tendency of a response style, the rater parameter θ, the item parameter β. The device is further configured to remove the response style parameter γ to generate a probability distribution of the rating value.
