This conference is intended as an inter-disciplinary exploration into adaptive hypertext and other kinds of flexible hypermedia systems (including but not limiting to Web-based systems). It aimed to draw together a number of research groups taking different approaches to adaptive and flexible hypertext systems, in order to promote the cross-fertilization of the ideas and highlight the prospects for future collaboration. The proposed conference builds upon and extends the scope of previous successful workshops held in conjunction with major international conferences. Time is coming now to bring together researchers on various aspects of adaptive system research in an event especially devoted to this topic. The conference will compass 3 main tracks, each on focussing on a particular topic in the field, and a parallel demo session.
