Abstract (in Japanese) (See Japanese page) 
(in English) The demand for information services considering personal preferences is increasing. In this report, we
propose a system for automatically acquiring personal preferences from TV viewer’s behaviors. Our system firstly
extracts intervals of interest and estimates the interest degrees for each extracted interval based on the temporal patterns in facial changes by Hidden Markov Models. Then, the viewer profile is created by associating the interest degrees with content information described in the metadata of the watched program. Experimental results show that the proposed system is able to correctly estimate interest degrees for extracted intervals with a precision rate of 72.8\% and a recall rate of 59.1\%, and that the created viewer profile is comparable to the actual preference of each viewer.
