Awareness of individual and group activities is critical to successful collaboration and is commonly
supported in collaborative graphics design systems (CGDS). Awareness of cooperative efficiency
visualized in fine granularity is valuable for finding out the bottlenecks in collaborative design
process. However, little work has been done. In this paper we propose a novel intelligent
cooperative efficiency evaluation mechanism via mining the reaction information. By visualizing
cooperative efficiency, cooperators are enabled to concentrate on the most of controversial part of
the cooperative work. Related algorithm that includes two key concepts: expectation and
convergence is proposed. The mechanism and algorithm have been realized in our prototype
system and are proved significantly promote the coordination efficiency.
