A group of users having a common preference and situation is called community where a service according to their preference and situation is provided. Real-time marketing for this service requires real-time property and accuracy of these preferences obtained by a service provider. Autonomous decentralized community system that consists of autonomous nodes and autonomous synchronization technology have been proposed to achieve timeliness by reducing the number of preferences data towards a service provider. Although this technology achieves high accuracy, many varieties of preference cannot be aggregated within a deadline. In this paper, heterogeneous processes about timeliness and accuracy are introduced. An autonomous cooperation technology is proposed to achieve both real-time property and accuracy. In this technology, each node autonomously switches from high-accuracy and low-response process to low-accuracy and high-response process. Consequently, high accuracy result in real-time is procured. Simulation results show effectiveness of the proposed technology.
