Most of the e-learning research topics focus on metadata of learning object. These studies extract useful information from metadata, and use them to organize the LOs. However, to understand the metadata is not enough to organize the multimedia-style LO in meaningful manner. The comprehensive multimedia-style LO is especially useful for mobile learners to choose what they really demanded. In order to attack the problem, this project uses multi-agent technique to develop a personalized hyper-seamless learning environment for managing LOs comprehensibly. Following that, the proposed environment coordinates two agents: Content Reorganize Agent, and Zone Agent to provide mobile learners the efficient multimedia-style learning experience. The CRA is responsible for reorganizing the discovered critical multimedia content by analyzing learner』s behavior and the multimedia』s annotation. The ZA is designed for terminal devices to monitor the learning behavior, and it sends the collected behaviors to CRA for evaluating. Moreover, the ZAs can communicate with each other, and they can self-organize as a group for sharing learning resources. Due to the cooperation of the two agents, the learning environment can give the properly multimedia-style LO for learners without bandwidth squandering. Finally, we expect this project can construct a comprehensive multimedia-style LO map for efficient personalized seamless learning.
