Traditional web-based learning platforms give the same educational content to each learner. Nowadays, these kinds of teaching environments are gradually replaced by individualized adaptive e-learning systems. This study deals with the design and implementation process of an innovative Dynamic Adaptive Hypermedia System (DAHS) named as "CleverUniversity". Learning styles are one of the most important factors in determining personal differences. Accordingly, our system allows students to take content of the course appropriate to their own needs and learning styles. By this means, the efficiency and effectiveness of learning activities would be improved. Our system is composed of five main components, first, learner's model, pedagogical model, domain model, content generator and multimedia database.
