Abstract(in English) | Content providers or directors have been searching for a means to objectively evaluate viewers' subjective states while viewing films. Even by using state of the art technologies of image, audio and natural language processing, it would not be easy to extract high level semantics from media contents that contribute to content evaluations. By regarding biological responses as 'features' of movie contents, we attempt to extract such high level semantics from movie contents. It is difficult to define a universal criterion to judge the value of arbitrary movie contents, since metrics for enjoyability largely depend on the genre. In this report, focusing on a specific genre, comedy, we validate our framework in which movie contents are evaluated via biological responses, by extracting viewers subjective mental states that contribute to movie-evaluations from brain activity obtained during movie viewing. We conducted experiments in which we measured viewers' fMRI responses for comedy movies and levels of humor they were experiencing during movie viewing via a response device. Assuming that there are several mental states before and/or after a humor report, we analyzed fMRI data by using a decoding technique (a machine learning algorithm). Then, we found that statistically significant prediction accuracies were derived from the decoders constructed using fMRI data obtained even at two seconds ahead of the humor reports. The objective measurement of 'expectation of humor' contributes to an evaluation of humorous scenes because we can obtain the detailed reactions of viewers for specific scenes. These results indicated that the objective measurement of movie-induced mental states contributes to a movie-evaluation, and showed the proof of concept of the frame work that evaluates movie contents via biological signals. |
