With the rapid development of MOOCs and other e-learning applications and platforms, the volume of e-learning resources has grown significantly in recent years. At the same time, a variety of modalities of learning resources are provided. The fast growth of e-learning resources results in the problem of information overload as learners are overwhelmed by the rich learning resources. In other words, it is increasingly difficult for learners to find required learning materials efficiently and effectively. We propose a powerful framework to organize e-learning resources and capture learning preferences by integrating various hidden relationships among learners, knowledge units and resources. Subsequently, the learning resources will be recommended at different levels. Firstly, learning resources are recommended to individual learner based on the contextualized learner profile so that personalized learning could be facilitated. Secondly, group member discovery could be achieved by assigning learners into groups based on their distance from contextualized group profiles. Thirdly, learning resources can be recommended to a class based on the aggregated class profile. Throughout the case studies, we have verified that the proposed framework is very flexible and powerful to support various kinds of e-learning applications in different scales.
