e-Learning has become a trend in the world nowadays. However, most researches neglect a fundamental issue - the e-Learners prior knowledge oil which the useful intelligent systems arc, based. This research employs the e-Learner's prior knowledge and mines his/her interior desire oil appropriate target courses or materials as a part of a personalization process to construct the overall e-Learning strategy for education.
This paper illustrates a novel web usage mining approach, based oil the sequence mining technique applied to e-Learners navigation behaviour, to discover patterns in the navigation of e-Learning websites. Three critical contributions are made in this paper: (1) using the footstep graph to visualize the e-Learners click-stream data so any interesting pattern can be detected more easily and quickly; (2) illustrating a novel sequence mining approach to identify pre-designated e-Learner navigation patterns automatically and integrating a back-propagation network (BPN) model smoothly; and (3) applying the empirical research to indicate that the proposed approach call predict and categorize the e-Learners' navigation behaviour with high accuracy.
