Motivation --Information Personalization

To increase the functionality of hypermedia by making it personalized.

Users with different goals and knowledge may be interested in different pieces of information with different presentation on a hypermedia page and may use different navigation(limiting browsing space, suggesting most relevant links to follow, or providing adaptive comments to visible links).

Definiton of  "Adaptive Hypermedia(AH) System"

By adaptive hypermedia systems we mean all hypertext and hypermedia systems which reflect some features of the user in the user model and apply this model to adapt various visible aspects of the system to the user.[Peter1]

The system should satisfy 3 criteria:

• it should be a hypertext or hypermedia system,
• it should have a user model,
• it should be able to adapt the hypermedia using this model (i.e. the same system can look different to the users with different models)

The critical feature: the possibility of providing hypermedia adaptation on the basis of the user model.
