Abstract: A server 20 of an event information distribution system 1 includes, as functions thereof, a sports game type identification module 2033 for identifying a target sports game for which an input of event information is to be accepted, an event information acceptance module 2034 for accepting an input of an event which has occurred in a sports game, an event information evaluation module 2035 for evaluating the accepted event information, an event information distribution module 2036 for distributing event information based on an evaluation result, and a reward offering module 2038 for offering a prescribed reward to a user based on the evaluation result.

Abstract: An information provision device in an information provision system includes, as its functions: a score control circuit that increases or decreases a provision timing score on the occurrence of a predetermined action; a timing determination circuit that determines the coming of the time to provide quiz information if the provision timing score exceeds a predetermined threshold; a priority control circuit that determines or changes, based on the situation of, e.g., a sport game on each occurrence of an action, priority associated with text information from which quiz information is generated; a quiz information generation circuit that generates appropriate quiz information based on the situation of, e.g., the sport game at the time determined; and a quiz information provision circuit that provides the generated quiz information to a user.

Abstract: An open market system includes: an information collection circuit that collects prediction information indicating details of a game predicted by prediction sellers; an entry acceptance circuit that accepts entry of tokens possessed by prediction purchasers; an information presentation circuit that presents, to the prediction purchasers who have entered the tokens, the prediction information collected by the information collection circuit and optimum prediction information based on the prediction information; and a distribution execution circuit that distributes, to one or more of the prediction sellers, the tokens entered by one or more of the prediction purchasers for the optimum prediction information.
