Adaptive Hypermedia Systems

Adaptive Hypermedia Systems are systems that modify the different visible aspects based on the user profile. To provide this adaptation, the system is modeled according to a user model, which stores the information about each user. This information can include knowledge, interests, goals and tasks, background and skills, behavior, interaction preferences, individual traits and context of the user. This chapter goal is to introduce Adaptive Hypermedia Systems fundamentals and trends. In this context this chapter identifies some methods and techniques used to adapt the content, the presentation and the navigation of the system. In the end, some applications (ELM-ART, Interbook, AHA!, AdaptWeb®) and trends (standardization, data mining, social web, device adaptation and gamification) are exposed. As a result, this chapter highlights the importance of the improvement and the use of adaptive systems.
