<P>PROBLEM TO BE SOLVED: To classify contents without depending on details of the contents. <P>SOLUTION: A classification information storage section 330 stores information of categories corresponding to contents of which the category is known. A history receiving section 310 receives an access history of contents. The access history includes information of users who have accessed the contents. A content information storage section 320 stores the access history, tabulates an access frequency of contents for each user, and stores a result of the tabulation. A classification section 340 uses the information stored in the classification information storage section 330 and the information stored in the content information storage section 320 to classify the contents of which the category is unknown. The classification section 340 classifies the contents of which the category is unknown on the basis of the access frequency of contents of which the categories are unknown for each user and the access frequency (and the category) of contents of which the categories are known for each user. <P>COPYRIGHT: (C)2012,JPO&INPIT |
