Abstract

In order to extract, with high accuracy, useful information from contribution information of social media, the present invention provides a processing apparatus 10 including: an acquisition unit 11 that acquires contribution information relating to a target area; a computation unit 12 that computes a degree of reliability of the contribution information, based on at least two of an activity area of a contributor of the contribution information, a degree of reliability of an estimation result of the activity area, a degree of disclosure of a profile of the contributor, an attribute of the contributor, an attribute of the activity area for the contributor, and a category of a content of the contribution information; and an output unit 13 that outputs the contribution information in which a degree of reliability of the contribution information is higher than a threshold value.
