With the great advance in semantic web, more and more studies focus on the importance of ontology and its applications. Through the graphical representation of ontology, the whole courseware structure and core knowledge about a subject domain can be clearly revealed, thus reducing the problems of learning disorientation for learners. This paper thus presents a personalized e-learning system based on ontology-based concept map for personalized learning. The constructed ontology-based concept map can depict the concept correlations between courseware. Moreover, the generated concept map was applied on the personalized learning path generation in order to promote the learning performance and efficiency in this study.
