Abstract: An object is to provide an information providing system and an information providing method in which an information providing device can provide information personalized for a user without an input of identification information of the user into the information providing device. A server device receives, from a terminal device that has acquired device identification information identifying the information providing device, the device identification information and user identification information identifying a user. The server device transmits information for the user identified by the user identification information to the information providing device identified by the device identification information. The information providing device receives the information for the user. The information providing device provides information based on the information for the user.

Abstract: One aspect of the present disclosure relates to a system for providing a recommendation for a game based on a game-centric relationship graph. The relationship graph is a graph depicting relationships between game and game users. One or more recommended games may be determined by leveraging the relationship graph. For example, recommended games may be identified based on graph proximities from candidate game nodes to a target user node or a mathematical score calculated from weight metrics of relationship branches.

Abstract: One aspect of the present disclosure relates to a system for proposing a content set for presentation to a user. A first content set containing one or more first content items may be provided to a client device for presentation to a user. Whether or not to provide a second content set, which may include different content items from the first content set, may be determined based on degree of lack of interaction of the user with said one or more first content items.
