a classified information storing unit for storing classified information having already been classified into a certain group and group specification information for specifying the group, in association with each other; and a confidence calculating unit for calculating confidence having a value depending on a probability that a group which is specified based on unclassified information as a target to be classified and classified information selected as reference information from among the stored classified information and into which the unclassified information should be classified is a true group,wherein the confidence calculating unit is configured to:
with respect to each classified information of the stored classified information, judge whether a first group and a second group match each other, the first group being a group which is specified based on the each classified information as judgment target information and based on classified information selected as a reference information candidate from among the stored classified information and into which the judgment target information should be classified, and the second group being a group specified based on the group specification information stored in association with the judgment target information; and calculate static confidence as one of the confidence based on a matching number as a number of judgment target information that the first group and the second group match each other.
