Abstract :
A role based hierarchical group awareness model (RHGAM) on the basis of the previous research was presented in this paper. Regarding role as the basis of the group cooperation, firstly RHGAM constructed a group cooperation environment (GCE), and then GCE was extended by group awareness content, awareness hierarchy, the task decomposition rule. The model divided the awareness information into four levels by decomposition and recombination using a role-task graph and the thinking of group structure. The time possibility analysis based fuzzy time and the implementation mechanism of the model to provide group cooperation and awareness mechanism in the project Personal Research Information Workspace were also discussed in this paper.
