摘要

PROBLEM TO BE SOLVED: To generate user's taste information on the basis of attribute information of contents meeting prescribed conditions.

SOLUTION: Program vectors of programs being user model generation objects are acquired in a step S231, and a topic inputted by the user is set as a filtering condition in a step S232. Program vectors are filtered on the basis of the filtering condition to extract program vectors meeting the topic in a step S233, and a user model vector is generated from the sum total of extracted program vectors in a step S234. Cosine distances between the user model vector and program vectors of candidate programs for obtaining recommended information are calculated in a step S235, and the prescribed number of programs out of candidate programs of which the program vectors have higher degrees of similarity to the user model vector are extracted in order from the highest degree as recommended information in a step S236. This invention is applicable to program recommendation apparatus .
