Abstract: In this paper a classification of adaptive hypermedia systems is presented. Advantages and disadvantages of these systems are also discussed. As a consequence, the need of evolution is argued. An adaptive and evolving hypermedia system is presented and outlined, where the user model is formalized by means of Petri Nets. Finally, an example shows how in our proposal the user model is initialized and updated during the browsing and how adaptation is carried out over the conceptual structure of navigation.
