8. An evaluation update method comprising:
generating evaluation information of an evaluation target based on first posting data posted by a first user of a plurality of users, the first posting data describing a first evaluation result of the evaluation target,
wherein the evaluation information represents an evaluation of the evaluation target, and the evaluation information includes a location of the evaluation target;
determining a value of an evaluation information index of the evaluation target, wherein
the value of the evaluation information index indicates a level of reliability of the evaluation information of the evaluation target,
the value of the evaluation information index is based at least on a number of postings within a predetermined distance from the location of the evaluation target with similar contents of the evaluation information,
the value of the evaluation information index decreases exponentially as time elapses from a point when the evaluation information was generated,
the value of the evaluation information index decreases according to a decrease of a coefficient representing an average value of voting information of the evaluation information over time since the value of the evaluation information was generated,
the average value of the voting information indicates an average of results of voting by at least a second user of the plurality of users on the evaluation information of the evaluation target, and
the voting is in response to inquiring the plurality of users whether the evaluation information is appropriate; and
when the value of the evaluation index becomes less than or equal to a predetermined threshold associated with the evaluation information index:
updating the evaluation information of the evaluation target by replacing content of the evaluation information with second posting data posted by the second user of the plurality of users, the second posting data describing a second evaluation result of the evaluation target, wherein the second posting data is distinct from the first posting data; and
updating the value of the evaluation information index according to the updated evaluation information of the evaluation target.
