A role-based and agent-oriented model for collaborative virtual environment

Collaborative virtual environment model and role scheme are two research branches in computer science. Collaborative activities need an effective mechanism to support participants' roles and rights 'while role schemes can be applied to this field. In this paper, we present a new generic role-based and agent-oriented model for collaborative virtual environment based on discussion of collaborative activity as an essential role in the research of CVE. It introduces role schemes to establish more efficient collaborative virtual environments. The proposed model includes two important parts: collaborative entity and collaborative event. It also advances intelligent entity in running state and collaborative federation in this model to describe cooperation in collaborative virtual environment.
