TUTORIAL DESCRIPTION
RBC is a computational thinking methodology.  It is an emerging technology that mainly uses roles as underlying mechanisms to facilitate abstraction, classification, separation of concern, dynamics, and interactions.  RBC will find wide applications in different fields, such as, organizations, management systems, systems engineering, and industrial engineering.  It is generally relevant to many research and engineering fields including Software engineering, Computer Security, Collaborative Intelligent Systems and Social Psychology (Fig. 1).  The goal of special RBC is to improve collaboration among people based on computers.  CSCW (Computer-Supported Collaborative Work) systems are computer-based tools that support collaborative activities and should meet the requirements of normal collaboration.  They should not only support virtual face-to-face collaborative environment but also improve face-to-face collaboration by providing more mechanisms to overcome the drawbacks of face-to-face collaboration.  The extended goal of general RBC is to improve collaborations among objects including humans, systems, and system components.  Roles can be used to improve the collaboration methodologies, upgrade the management efficiencies, keep the consistencies of systems, and regulate the behaviors of system components and systems.

This tutorial will first review the current situation of CSCW research and the applications of role concepts.  It will then explain the reasons of proposing role-based collaboration.  Then, a synthetic view of roles in collaboration will be proposed.  Based on the role concept, the general process of role-based collaboration is demonstrated.  To support role-based collaboration efficiently, the architecture of role based collaborative systems and the system model E-CARGO are described.  To demonstrate the application of RBC, two case studies of RBC applications are presented: role-based multi-agent systems and role-based software development.  Lastly, potential applications of RBC and challenges that need further research are predicted.

INSTRUCTOR BIOGRAPHY

Haibin Zhu is an associate professor of the Department of Computer Science and Mathematics, Nipissing University, Canada.  He received B.S. degree in computer engineering from Institute of Engineering and Technology, China (1983), and M.S. (1988) and Ph.D. (1997) degrees in computer science from the National University of Defense Technology (NUDT), China.  He was a visiting professor and a special lecturer in the College of Computing Sciences, New Jersey Institute of Technology, USA (1999-2002) and a lecturer, an associate professor and a full professor at NUDT (1988-2000).  He has published about seventy research papers, five books (four in Chinese and one in English) and one book chapter on object-oriented programming, distributed and collaborative systems, computer architecture and intelligent systems.

Dr. Zhu pioneered the research on role-based collaboration (RBC) in 2002.  His research has been sponsored by IBM Eclipse Innovation Grants and National Science and Engineering Research Council (NSERC) of Canada.  He has published more than 20 papers related to this topic since 2003 (please see the attached publications).  He has been invited to give many presentations on RBC in universities and research institutions.  He offered a half-day tutorial of RBC for CODS’07.  He also gave a one-hour seminar on RBC for the workshop on RBC of CSCW’06.  Due to his research on collaboration, he was appointed as co-chair for the technical committee of Distributed Intelligent Systems of the IEEE SMC society in 2006.
