Adaptation in Multimedia Systems

Multimedia systems can profit a lot from personalization. Such a personalization is essential to give users the feeling that the system is easily accessible especially if it is done automatically. The way this adaptive personalization works is very dependent on the adaptation model that is chosen.We introduce a generic two-dimensional classification framework for user modeling systems. This enables us to clarify existing as well as new applications in the area of user modeling. In order to illustrate our framework we evaluate push and pull based user modeling in user modeling systems.Paul de Vrieze received his Masters degree in Information Science in 2002 from the University Of Tilburg, The Netherlands. He is currently junior researcher at the University of Nijmegen. His main research interests include adaptive systems and user modelling.Patrick van Bommel received his Masters degree in Computer Science in 1990, and the degree of Ph.D in Mathematics and Computer Science, from the University of Nijmegen, the Netherlands in 1995. He is currently assistant professor at the University of Nijmegen. His main research interests include information modelling and information retrieval.Prof.Dr.Ir.
