Abstract: An example of an information processing system includes one or more terminal apparatuses and a server. Each of the one or more terminal apparatuses transmits, to the server, action information indicating an action of a user regarding the terminal apparatus. The server receives the action information from the terminal apparatus. The server stores, for respective types of actions, pieces of history information, each indicating a numerical value corresponding to history of the action of the user. Based on the received action information, the server updates history information corresponding to the action information. Under the condition that a combination of the plurality of pieces of history information satisfies a predetermined combination condition, the server transmits provision information to a terminal apparatus that is the same as or different from the terminal apparatus as the transmission source of the action information.

Abstract: Since only users registered in a chatting service are subject of friends on the chatting service, unregistered users cannot become friends. A server apparatus controls a message exchanged between registered users who are registered in a chatting service, and controls a message exchanged between a registered user and an unregistered user. Also, the server apparatus manages a friend list of the registered user, and recommends other user to be added to the friend list with respect to the registered user. Also, the server apparatus determines other user to be recommended to the registered user by using a predetermined condition set according to the presence or absence of registration in the chatting service.

Abstract: The server device stores image information uploaded by any registered user in conjunction with the identification information of the uploading user who uploaded said image information and manages the association between tagged image information that is subjected to tagging and tagged users by performing a tagging operation that associates image information uploaded to the image information storage unit by the uploading user with any registered user in response to a request from the uploading user or other registered users.
