Information processing apparatus capable of properly reflecting a change in a user's preference or interest

摘要

The present invention is intended to properly reflect the change in user's preference and properly infer the user's interest in newly added attributes, thereby realizing contents recommendation which is close to user's interest. A topic selection block deliberately selects the interest data which is low in the degree of importance and a dialogue generation block generates queries. A response input block accepts a response to a query displayed by a dialogue display block and changes the interest data in accordance with the contents of the accepted response. The present invention is applicable to personal computers or HDD recorders.
