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.

A communication skill evaluation system including: an audio input device; a measurement device; an utterance period detection unit that, based on the audio information input by the audio input device, detects an utterance period and a participant who spoke in each utterance period; a participatory role assignment unit that assigns a participatory role to each participant in accordance with whether or not each participant spoke in each utterance pair composed of two utterances obtained in chronological order from each utterance period; a feature quantity extraction unit that, based on the measurement results by the measurement device, extracts a non-verbal feature quantity for each participant, relating to the non-verbal action at the end of the utterance in each utterance period; and an estimation unit that estimates communication skill for each participant based on a combination, in each utterance period, of the participatory role and the non-verbal feature quantity.

In communication performed among multiple participants, at least one of a participant who will start speaking next and a timing thereof is estimated. An estimation apparatus includes a head motion information generation unit that acquires head motion information representing head motions of communication participants in a time segment corresponding to an end time of an utterance segment and synchronization information for head motions between the communication participants, and an estimation unit that estimates at least one of the speaker of the next utterance segment following the utterance segment and the next utterance start timing following the utterance segment based on the head motion information and the synchronization information for the head motions between the communication participants.

An inattentive state determination device includes an observed amount acquiring means for acquiring information on the driver's line of sight and at least one of either information on driving operations or information on the traveling state as an observed amount; and an inattentive state determining means for determining the inattentive state of the driver based on the stochastic relationship between the inattentive state and the observed amount as well as the observed amount acquired by using the observed amount acquiring means. In addition, the inattentive state determining means calculates the probability that the driver is driving inattentively and determines that the driver is driving inattentively when the calculated probability exceeds a threshold.
