A Distributed Model for Virtual Group Learning System

In order to build an open, collaborative and efficient visual group learning system (VGLS for short below) in a wide area network (WAN for short below)environment, such as the Internet, this paper studies how to combine multiple techniques such as the mobile agent, ontology and Web services composition to build a VGLS. As the research result, a distributed model for VGLS (DM4VGLS for short below) is proposed in this paper. The application framework of the DM4VGLS model is illustrated. Based on the above application framework, the components within the DM4VGLS are introduced with an emphasis on the collaborative mechanism of them. A simulation prototype based on jadex, a belief desire intention (BDI) reasoning engine that allows for programming intelligent software agents in XML and Java, is developed. The initial experiments show the feasibility of the proposed DM4VGLS model.
