Abstract

The present mechanism aims to effectively restrict access of a general user to an inappropriate information piece at the judgment of an information manager. In order to pick up a desired information from an information storage medium or an information communication network while excluding inappropriate information, an information manager inputs suitability of information (a teacher signal) to an information presented at a user terminal to a group profile learning unit and prepares a group profile reflecting suitability of the information as specified by the information manager using the teacher signal. At a score calculating unit, a score signal indicating suitability of information is calculated for each information using the group profile, and access of an information user in a group to inappropriate information is restricted.
