The aim of this 3-hour tutorial is to introduce the participants to adaptive hypertext and hypermedia, a new area of research in human-computer interaction, to present a number of recent efficient adaptive hypermedia technologies on a level of detail which will enable the use of these technologies in the attendees' own systems, and demonstrate the implementation of adaptive hypermedia on the WWW. The tutorial is oriented to an intermediate level audience: HCI researchers and practitioners interested in designing advanced hypermedia applications and advanced WWW applications, as well as researchers who work in, or who wish to learn more about, the field of adaptive and intelligent interfaces.
