The Virtual Learning Commons Architecture Based on Semantic Technologies

Virtual Learning Commons (VLC) is a new web-based virtual learning environment to support learning, teaching, research and knowledge sharing by integrated digital library, e-learning system, social network, academic support tools, and so on. In this paper, a new semantic based VLC architecture is proposed, which reveals the logical relationship among the virtual environments, the functional levels, the virtual service organization, and other components. The five-layer structural model is described in detail. Finally, a prototype system of the semantics-based VLC is implemented. The case study shows that the proposed semantics-based architecture and structural model have great theoretical and practical value in guiding the construction of VLC.
