Encourage Participants' Contributions by Roles

Teamwork requires every member to contribute to the team. Encouraging people to contribute in collaboration is exciting and challenging. The model E-CARGO could support collaboration with human users, agents, roles and groups. By assigning roles and transferring roles, we can organize and encourage human users and agents to contribute in collaboration and make the teamwork more profitable. This paper analyses the behaviors of people in collaboration, proposes a methodology with roles to improve collaboration by assigning human users more roles, discusses the basic methods to evaluate and promote human users with roles and relevant properties and describes the implementation of the kernel mechanisms.
