Provided is an information processing device that, by means of a novel technique, is capable of evaluating a user on the basis of the results of actions performed between users or user groups. The information processing device does the following: obtains action results data that indicates the results of actions performed between a plurality of users or user groups; performs multiple executions of trace processing, which consists of start-point selection processing that randomly selects a target from among the plurality of users or user groups and target selection processing that repeats, until a prescribed condition is met, processing that newly selects as the next target another party to the action that the current target is performing, on the basis of the action results data; and, for each of the plurality of users or user groups, calculates an evaluation value for the user or user group in accordance with the number of times users or user groups were selected as a target in the multiple iterations of trace processing. |
