A practical approach for automatically constructing concept map in E-learning environments

With the prevalence of web-based learning, the application of concept mapping, as a powerful diagnostic and instructional tool, has been widely exploited in both education and computer science. In recent years, several methods have been presented to automatically construct concept map that achieved encouraging results, while ignoring some critical issues when applied in actual E-learning system. In this paper, we propose a practical approach for constructing concept map, which is adapted to the dynamic character of a real system. Moreover, we apply fuzzy set theory and fuzzy reasoning basis on fuzzy rules for similarity degree between two concepts, to find direct prerequisite relationship among concepts. It provides a useful way to improve accuracy and reduce complexity of the concept map.
