EVALUATION APPARATUS, DISTRIBUTED STORAGE SYSTEM, EVALUATION METHOD, AND EVALUATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To enable fast detection of a sudden data spike in an evaluation value estimation algorithm.SOLUTION: An evaluation apparatus comprises: a calculation unit 19 that calculates an evaluation value for an evaluation target content using an evaluation value estimation algorithm on the basis of a count value for the evaluation target content and the total value of respective count values for a plurality of contents; a confirmation unit 13 that confirms whether the total value of the respective count values for the plurality of contents has reached a predetermined value; and a processing unit 14 that shrinks the respective count values for the plurality of contents when the total value of the respective count values for the plurality of contents has reached the predetermined value.
