Aims and Objectives I

• You will learnabout the major issues in
  user-adaptive systems
• You will understand the various components that
  are needed to build user-adaptive systems of
  various types
• You will be able to design an adaptive system to
  solve a particular type of problem
• You will know how to evaluate the adaptive system
• Worth 6 ECTS credits
• Examination by unseen paper only

Introduction

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

Definition
By 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

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

Watch HyperLand

• Written by and starring Douglas Adams (The
  Hitchhikers Guide to the Galaxy)
• Co-starring Tom Baker (Dr. Who)

8
As you watch HyperLand

• It was produced in 1990
• The 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?
