It is indeed important to implement e-Learning platforms for education and training purposes in a variety of domains. However, facing the enormous amount of learning resources, guidance on e-Learning platform for meeting the educational objectives is still a neglected issue. The learning experiences cannot be optimized and personalized. In this study, a semantic and systematic mechanism is proposed to discover the educational objectives of learning resources with competency information on e-Learning platform. To verify the feasibility of mechanism proposed in this study, the design and implementation of prototype system for the assessment of e-Learning effectiveness using the proposed mechanism are also discussed and demonstrated. By feasibility verification with system implementation for practical requirement, the effectiveness of the proposed mechanism can be basically certified.
