PREFERENCE EXTRACTING APPARATUS, PREFERENCE EXTRACTING METHOD AND PREFERENCE EXTRACTING PROGRAM

摘要

PPROBLEM TO BE SOLVED: To generate preference information on which user's preference is reflected with high precision. PSOLUTION: A program recording and reproducing apparatus 1 extracts a keyword KW from a television program being broadcast by a subtitle decoder 22 and a keyword extracting unit 23, displays a keyword extraction icon IC on a display screen to make a user evaluate the program at the point of time, and increases or decreases a preference value VP corresponding to the keyword KW by a preference information managing unit 24 based upon the evaluation result. Consequently, the preference value VP for the keyword KW having high relativity to one scene of the television program can be increased or decreased based upon the user's evaluation of the one scene, so the user's preference can be reflected on a preference information database DBP with high precision.
