Abstract
Record history record processing accumulates all user operations relating to program recording in a storage as a recording history. Preference change analysis processing extracts recorded programs in the most recent period from the recording history, obtains the weight of a word in the recorded program from an index from an EPG, adds the weight of the word to a preference in a period. The preference in programs for a period immediately preceding the most recent period is normalized, and a degree of similarity to the preference in the most recent period is calculated. Preference query generation processing emphasizes (five-fold) the weight of the words contained in the recorded programs in the period (June) and generates a preference query.
