2 2 of 13 CSA3200: Lecture 1 © Chris Staff University of Malta 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

4 4 of 13 CSA3200: Lecture 1 © Chris Staff University of Malta 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

5 5 of 13 CSA3200: Lecture 1 © Chris Staff University of Malta 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 Available on-line at: / UMUAI.pdfhttp://www.contrib.andrew.cmu.edu/~plb/UMUAI.ps

6 6 of 13 CSA3200: Lecture 1 © Chris Staff University of Malta 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

7 7 of 13 CSA3200: Lecture 1 © Chris Staff University of Malta Watch HyperLand Written by and starring Douglas Adams (“The Hitchhiker’s Guide to the Galaxy”) Co-starring Tom Baker (Dr. Who)

8 8 of 13 CSA3200: Lecture 1 © Chris Staff University of Malta 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?
