Abstract: An information processing device according to the present application includes a generation unit and a providing unit. The generation unit uses a model that is trained to learn a relationship between a criterion for classifying users of a first company and a criterion for classifying users of a second company to generate a criterion (common key) for classifying the users of the second company into a first category, from the criterion for classifying the users of the first company into the first category. The providing unit provides a criterion generated by the generation unit.

Abstract: An information processing device includes: an acquisition unit that collects data on an unspecified large number of users; a generation unit that generates a model for calculating a score of a user group satisfying a predetermined condition by using the data collected; a reception unit that receives designation of a user condition from a business operator on a client side; a calculation unit that calculates a score of a user group satisfying the user condition by using the model; and a providing unit that provides information regarding the score calculated to the business operator.

Abstract: Digital media delivery devices, methods, and programs select digital media for display within digital content on a terminal device based on a degree of reliability of an evaluation value for the digital media. The devices, methods, and programs access a memory that stores digital media information for a plurality of items of digital media including an evaluation value, and a degree of reliability that reflects the reliability of the evaluation value. The devices, methods, and programs, receive a request for digital media for display within digital content on the terminal device via the network interface, identify a group of the plurality items of digital media each having the degree of reliability above a predetermined threshold, select an item of digital media from the identified group having a highest evaluation value, and transmit an identification of the selected item of digital media via the network interface.
