Information provision system, specific-information generation device, and specific-information generation method

In this invention, user attribute information and preference information is generated with increased precision. This information provision system (100) comprises a first-history collection device, a second-history collection device, and a specific-information generation device. The specific-information generation device generates specific information regarding a user's attributes and preferences on the basis of first history information obtained from the first-history collection device and second history information obtained from the second-history collection device. The first history information includes an access history for a Web terminal and a network identifier for said Web terminal. The second history information includes an operation history for a home-appliance terminal, a home-appliance-terminal identifier, and a network identifier for the home-appliance terminal.
