PROBLEM TO BE SOLVED: To provide advertisement information with high availability to a user with a simple configuration. SOLUTION: The user is caused to select preset choices in preparing a schedule, a memo, a daybook, a housekeeping book, etc. Many pieces of advertisement information are registered to be provided to the user while associated with the choices. Choices inputted to the schedule, the memo, the daybook, the housekeeping book, etc., are extracted, and the advertisement information associated with the choices is retrieved and extracted to be provided to the user. Then, in the case of using the choices, expression is not different according to a user and ambiguousness does not exist in comparison with a case where a natural language is used. Therefore, information with high availability to the user can be retrieved and extracted even with a simple configuration. In other words, a high advertisement effect can be expected. |
