XML-based agent communication in a Distributed Learning Environment

A dramatic increase in the development of technology-based teaching and learning has been witnessed in the past decade. Distributed Learning Environments (DLEs) have emerged rapidly, which blend traditional and IT-based learning with the aid of distributed environments and learning communities. In this paper, we address the issues of collaborative agent communication in DLEs through describing 1) a multi-agent architecture supporting DLEs, 2) agent communication policies to govern the conversation among agents, and 3) XML-based language facilities and algorithms to facilitate communication among agents in DLEs.
