Introduction
Introduction to Adaptive (Hypertext) SystemsAdaptation is the process of automatically
determining changes in the environment (user interests) and modifying the system behaviour (interaction/information space) accordingly

Definition
“[B]y adaptive hypermedia 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”
Brusilovsky, P. (1996). Methods and techniques of adaptive hypermedia, in User Modeling and User-Adapted Interaction 6 (2-3), pp. 87-129. Available on-line at: http://www.contrib.andrew.cmu.edu/~plb/UMUAI.ps / UMUAI.pdf

Perceived benefits of AHSes
Users are able to interact with the system according to their needs and requirements
Information accessed by users is adapted to their level of competence
Users' view of the information space is adapted to their needs and requirements
System may be able to automatically describe user interests, even if user is unable to do so

As you watch HyperLand
It was produced in 1990The WWW has been in widespread use
since only 1993 with the release of NCSA Mosaic!
Look for evidence of “adaptation”What would you need to build a similar
system? What are the issues?
