Abstract
An input of a data group is received in which tag ID-appended data and time information on time the tag ID-appended data was created are associated; the number of instances is counted of the tag ID-appended data, to which a tag identified by a tag ID has been appended, occurring in each time slice for each tag ID included in the tag ID-appended data and for each time slice obtained by dividing a timeline by a predetermined duration, and the tags are extracted as a few exuberant and useful minority tags in a case where the counted number of instances is greater than a predetermined instance number threshold value and where a ratio of the time slices in which the number of instances does not satisfy a predetermined criterion is greater than a predetermined ratio threshold value; and data in which a score satisfies a predetermined criterion is determined.
