<P>PROBLEM TO BE SOLVED: To evaluate whether contribution information is reliable or not. <P>SOLUTION: When contribution information of a user about any arbitrary content is received, in an aspect, an evaluation apparatus identifies a location of the content. Furthermore, in an aspect, the evaluation apparatus determines whether or not a storage device which stores a behavior history of the user stores therein a behavior history before a contribution date in which the contribution information is contributed, and indicating the presence of the user in the identified location. Moreover, when it is determined that the behavior history indicating the presence is stored, in an aspect, the evaluation apparatus evaluates that reliability of the contribution information is higher than that in the case where it is determined that the behavior history indicating the presence is not stored. <P>COPYRIGHT: (C)2013,JPO&INPIT |
