            The 2nd Workshop on Adaptive Hypertext and Hypermedia

                           Held in Conjunction with

                               HYPERTEXT '98:

         The Ninth ACM Conference on Hypertext and Hypermedia

                    Pittsburgh, PA, USA, June 20-24, 1998



Workshop Theme:

With the growing size, complexity and heterogeneity of current hypermedia
systems, expecially the World Wide Web, comes the need
to provide more flexible mechanisms for delivering information to the
user. That is, we require mechanisms which can modify documents
on-the-fly in order to take the user's needs into account. Static
hypertext documents suffer from an inability to be all things to all
people; document and multimedia authors must write multiple documents
for different users rather than a single document which can
dynamically modify its content in order to address a particular user's
knowledge or the context of delivery.

A possible remedy for the negative effects of the traditional
"one-size-fits-all" approach in the development of hypermedia systems is to
equip them with the ability to adapt to the needs of their individual
users. A possible way for achieving adaptivity is by modeling the users and
tailoring the system's interactions to their goals, tasks and interests. In
this sense, the notion of adaptive hypertext/hypermedia means a hypertext
or hypermedia system which reflects some features of the user and/or
characteristics of his/her system usage in a user model, and utilizes this
model in order to adapt various aspects of the system's output to the user.

This workshop is intended as an inter-disciplinary exploration into
adaptive hypertext and other kinds of flexible hypertext systems. It aims
to draw together a number of research groups taking different approaches to
adaptive and flexible hypertext systems, in order to promote the
cross-fertilisation of ideas and highlight the prospects for future
collaboration. The target research areas for the second Adaptive Hypertext
and Hypermedia workshop include:

- Adaptive hypertext and hypermedia (adaptive navigation support and
adaptive presentation within an existing hypertext network of documents)

- Dynamic hypertext (employing text generation or other techniques to
dynamically create both the hypertext network and the documents within
the network as the user requests them)

- Information retrieval and filtering (the use of information
retrieval or other techniques to determine the relevance of the nodes
within a static hypertext network for the individual user)

- Intelligent hypertext (automatic linking, similarity-based navigation,
concept-based navigation).

Some related events which have been held in the past include:

- Flexible Hypertext Workshop, held at the Eighth ACM
International Hypertext Conference (Hypertext'97).

- Intelligent educational systems on the World-Wide Web, held in
conjunction with the 8th World Conference on Artificial Intelligence
in Education (AI-ED97).

- Workshop on Adaptive Systems and User Modeling on the World Wide
Web, held in conjunction with the Sixth International Conference on
User Modeling (UM'97).  (

- Workshop on User Modelling for Information Filtering on the World
Wide Web, held in conjunction with the Fifth International Conference
on User Modeling (UM'96).

- Workshop on Adaptive Hypertext and Hypermedia held in conjunction
with the Fourth International Conference on User Modeling (UM'94).

Workshop Focus:

There has been a significant amount of research in this area over the
past five years (see workshop theme for more information), but two
recurring issues have become increasingly important, and these will be
the focus of this workshop:

- World Wide Web: The Web is both a new application area and a new
challenge for adaptive and flexible hypertext research. Web-based
applications are expected to be used by a much greater variety of users
than any earlier standalone application. Web-based applications naturally
need to be flexible; a Web-based hypertext application which is designed
with a particular class of users in mind may not suit users of other
classes. At the same time, developing adaptive and flexible hypermedia
systems on the Web, we can investigate a number of new opportunities such
as user model sharing or the use of group models.

- Evaluation: One of the key issues which arose from the first
flexible hypertext workshop and which has been aired again recently on
the adaptive hypertext mailing list is the importance of the
evaluation of adaptive and flexible hypertext systems. In particular, since the
main goal of these systems is to maximise the suitability of a
document to the user's knowledge and needs, evaluation is an essential
aspect in the development of these systems. However, very little
research has been done which confirms the advantages of such systems
or which demonstrates how this evaluation process might be done.

Workshop Format:

The workshop will run for one full day before the main Hypertext'98
conference. The number of attendees will be limited to 20-25 in order to
encourage participation in workshop discussions. Participation will be on
the basis of submitted position papers or by invitation. The workshop will
include a limited
number of paper presentations and general group discussions. Group
discussions will focus on the issues raised in the position papers, as
well as on some focus questions. A workshop dinner will also be
organized to encourage informal discussion.

The programme will include:

     Welcome and Introduction
     Workshop Sessions consisting of:
          1 to 2 Position Paper Presentations (15-30 minutes), and
          Group Discussion on the Issues Raised (30-60 minutes)
          Planning for post-workshop activities
          Conclusions and Wrap-up
     Workshop Dinner

The proceedings will be compiled into a technical report after the

Position Papers:

We invite two categories of submissions. Persons wishing only to attend the
workshop should submit a 1-2 page position paper or a research summary
including a list of relevant publications. Persons wishing to make
presentations at the workshop should submit full papers (up to 8 pages,
12pt font) describing demonstrated techniques for improving the adaptivity
and flexibility of hypertext documents. We are particularly interested in
papers which present innovative solutions to adaptive and flexible
hypermedia, investigate adaptive and flexible hypermedia in the context of
the WWW, and those which concern evaluation techniques for such systems. We
are also interested in receiving papers assessing the benefits and
downfalls of providing flexible documents, and papers of a more speculative
nature which focus on the future of adaptive and flexible hypertext
systems. Those aspects of the paper which are important for discussion in
the workshop should be clearly outlined in the paper.

All papers must include in the first page: the title, author's name(s),
affiliation, mailing address, phone number, e-mail, home page URL. Full
papers must also include an abstract of 200 words maximum and up to five

Electronic submission of the URL address of the position paper will be
preferred, although papers submitted as ascii (html format) or RTF files
will be accepted. To submit a position paper, send the URL address or
an ascii/RTF version of the paper itself to Peter Brusilovsky at [log in to unmask]

Before the workshop, all attendees will be able to access the position
papers from the web. We strongly encourage attendees to read these
before the workshop in order to facilitate discussion.

Important Dates:

     20 April 1998: Submission of position papers
     10 May   1998: Notification of acceptance or rejection
      1 June  1998: "Camera-ready" copies due
