A VLE system based on Semantic Web and Ontology: Model and implementation

With the continuous development of computer theories and technologies in the field of education, virtual learning environments (VLEs) are widely used in network-based education because of their features flexibly supporting teaching and learning activities and instructional management. In this paper, based on the study of existing virtual learning environment systems, and taking individualized creation and performance of educational processes as the core, we focused on the problems that how to set up various Non-linear learning sequences and comprehensive execution conditions of learning Units. Then, a model of virtual learning environment was proposed and implemented through adopting the theories and techniques of Semantic Web, Ontology, and UML. The study can efficiently meet the individualized requirements of educators and learners, thereby further optimizing the efficiency of teaching and learning.
