Super-consumer based reputation management for web service systems

In this paper, we propose a mechanism of using super consumers to manage reputation. Super consumers are consumers with more capabilities, such as cpu power, storage and bandwidth. Super consumers can serve as reputation managers to build global reputation for a service based on the opinions from all the members in the system. Super consumers can also build community-based reputation for a service, by forming their own communities based on similar interests and judgement criteria. Our experiments show that the system using both global and community-based reputation can perform better than the system using just global reputation.
