Abstract: Exemplary communication system 1 includes game devices 10, communication terminals 20, and game support server 30. Game devices 10 enable users to perform a multi-play activity. Each of communication terminals 20 runs an application associated with corresponding game device 10. Game support server 30 divides communication terminals 20 into separate communication groups in accordance with a situation of the multi-play activity performed by game devices 10 so that communication terminals 20 belonging to a same communication group can communicate with each other.

Abstract: An extraction device according to the present application includes an acquisition unit and a notification unit. The acquisition unit makes a web search engine execute extraction processing based on an arbitrary query received from an information user and acquires, as an extraction result, the number of users corresponding to the arbitrary query from behavior histories of users to be processed. The notification unit notifies the number of users acquired by the acquisition unit to the information user who posts the arbitrary query. More specifically, based on a query related to setting of a condition about behavior or an attribution of the user, the acquisition unit acquires the number of users corresponding to the query.

Abstract: Communication system 1 includes communication terminal 20A and game support server 30. Communication terminal 20A runs a game support program associated with game device 10A, to send invitation information to invite user B of game device 10B to a room enabling user A of game device 10A to perform a multi-play activity. Game support server 30, on receiving the invitation information sent from communication terminal 20A, or an invitation acceptance notice sent from communication terminal 20B running a game support program associated with game device 10B, which terminal has received the invitation information, enables users A and B to perform a multi-play activity in the room.
