CFP – Call for Papers ACM Hypertext 2005

The ACM Hypertext Conference is the foremost international conference on hypertext and hypermedia. It brings together scholars, researchers and practitioners from a diverse array of disciplines creating a forum that promotes exchange of ideas and opinions.
The 16th International ACM Conference on „Hypertext and Hypermedia: Concepts and Tools for Supporting Knowledge Workers” (HT 2005) will be held in Salzburg, Austria, on 6-9 September 2005. Following in the footsteps of early hypertext pioneers, the conference invites original contributions on concepts, methodologies and tools for supporting knowledge workers. HT 2005 invites scholars, researchers and practitioners from all disciplines to participate in this event and exchange ideas, theories and experiences regarding the use of hypermedia to augment the capabilities of knowledge workers.
Knowledge workers add value by processing existing information to create knowledge that can be used to define and solve problems within organizations. In achieving their objectives they continuously search, gather, analyse, associate, compare and organize information. Confronted with the vast amount of diverse information today, knowledge workers require new concepts, methodologies and tools that boost their everyday activities. The Hypermedia community seeks to explore how to augment the skills of knowledge workers and hence their efficiency.
In order to support knowledge workers during their tasks of searching and locating information, collaborating and sharing knowledge, assessing organisational efforts as well as handling unconventional multi-dimensional facts, this year we have broadened the scope of the conference by adding new themes that focus on exactly these activities. These include “Hypermedia and information retrieval”, “Collaborative hypermedia”, “Hypermedia engineering” and “Time and synchronization in hypermedia”.


In addition to interdisciplinary work describing the application of hypermedia concepts and technologies in other fields, HT 2005 encourages submissions that address broad topics, especially concerning one or more of the following themes:

Hypermedia in Digital Libraries

Chair: John Leggett, Texas A&M University.
Digital libraries require flexible, dynamic, and adaptable structuring techniques to transform media collections into meaningful entities. Hypermedia offers a number of structuring paradigms that enables the creation of semantics and thus meaning. We seek contributions that explore the ways in which the rich variety of structuring facilities represented by hypermedia technology can be used to address the challenging tasks faced in the digital libraries field.

Hypermedia in the Humanities

Chair: Ziva Ben-Porat, Tel Aviv University.
Co-chair: George Landow, Brown University.
Theoretical and applied work in areas like linguistics, cognitive psychology, semiotics, philosophy, art and music have explored many ways of coding and organizing conceptual knowledge as well as uncovering and analyzing the structures that lie underneath them. Compared to these ways, hypermedia research has to offer only trivial, shallow and for some domains inconvenient organizational paradigms. We encourage submissions in these and related areas that show how multi-dimensional structure has been used to describe, represent, and explain different types of information and how this can inform research in hypertext.

Hypermedia and Information Retrieval

Chair: Narayanan Shivakumar, Google.
Co-Chair: Vasilis Vassalos, Athens University of Economics and Business.
Navigational access to information spaces, as provided by hypermedia, is by itself not sufficient. For large and distributed hypertexts, information retrieval becomes extremely crucial. Conversely, structures in hypertexts provide useful information that can strengthen the usage of information retrieval systems. We are interested in contributions that explore the relationship between hypermedia and information retrieval and demonstrate how information retrieval can address issues of hypertexts and vice versa.

Adaptive and Adaptable Hypermedia

Chair: Paul De Bra, Eindhoven University of Technology.
Co-chair: Helen Ashman, University of Nottingham.
In many cases, one text, one set of relationships, does not fit all users. Adapting the text and the set of relationships to the needs of individual users greatly enhances navigation and comprehension of information spaces. Adaptive and adaptable hypermedia attempts to create foundations that allow such flexible information spaces by explicitly modelling the user and his/her needs. In this theme we seek contributions encompassing systems, methodologies, and user models for the adaptation, filtering and personalization of hypertext documents. Additional subjects include interaction design for adaptable or adaptive systems, adaptive and intelligent learning environments, recommender systems, reflective user models, and agent-based adaptation, as well as rigorous evaluation of such systems.

Hypermedia Engineering

Chair: Franca Garzotto, Politecnico di Milano.
Co-Chair: Sotiris Christodoulou, University of Patras.
Moving from prototype to real-world, industrial strength hypertext systems and applications require attention to the development process. Hypermedia engineering focuses on such issues in an attempt to create the necessary tools that guarantee the delivery of robust, cost-effective, value added hypertext applications. We encourage contributions in the areas such as modelling hypertext applications and authoring documents, hypertext application development environments and methodologies, metrics for the evaluation of processes, environments, applications and technologies, real-world experiences and best practises.

Literary Hypermedia

Chair: Jim Rosenberg.
Co-chair: Jill Walker, University of Bergen.
Since the medium affects the writing, the question of how writing changes with the introduction of electronic media in general and hypertext in particular is relevant and challenging. We welcome papers on the theoretical and practical opportunities and challenges posed by the convergence of hypermedia systems and traditional written texts. A small list of topics might include: the nature of hypertextual time, cybertext/algorithmic anatomy, hypertext narratology, hypertext anti-narratology, the role of code in literary hypertext, hypertextual close reading, literary interfaces, minimalist hypertext, maximalist (sculptural) hypertext, the nature of hypertextual genre and the role of blogging in reading and writing.

Ubiquitous and Physical Hypermedia

Chair: Kaj Gronbaek, Aarhus University.
Co-chair: Dave Millard, University of Southampton.
The traditional line between physical and virtual world is now beginning to dissolve, allowing relationships that span both worlds. Furthermore, capturing the relationship that exist only in the physical world and representing them in the virtual world opens new and challenging opportunities. We solicit contributions that explore the interface between the physical and virtual world, model and graft physical world properties into hypermedia, introduce hypermedia into the physical world to augment reality, present devices that enable the digital life and innovative uses of this technology for work, play, and creative expression.

Spatial Hypermedia

Chair: Kumiyo Nakakoji, University of Tokyo.
Co-chair: Claus Atzenbeck, Aalborg University Esbjerg.
Going beyond the traditional node-link model, spatial hypermedia uses spatial properties – such as geometric and temporal placement, visual similarity – to express and convey relationships and thus semantics. We are interested in contributions that explore this structuring technique, including systems, user interfaces and metaphors, visualizations, methodologies and experience reports.

Collaborative Hypermedia

Chair: Weigang Wang, University of Manchester.
Co-chair: Jessica Rubart, Fraunhofer IPSI.
Authoring hypertext documents becomes an even more challenging task when situated from a single user to a group environment. Collaborative hypermedia deals with all aspects of how hypermedia technologies can be used to support sharing and coordination of work between multiple users that wish to create information spaces that reflect the ideas of a community. Papers are welcomed that deal with such aspects of hypermedia, a small sample of which might be: innovative infrastructures and systems that support collaboration, technological issues such as access, notification and concurrency control, new potential application domains as well as the role of collaborative hypermedia in learning environments.

Time and Synchronisation in Hypermedia

Chair: Lloyd Rutledge, CWI Amsterdam.
Co-chair: Jocelyne Nanard, LIRMM, CNRS/Univ. Montpellier.
Most hypermedia frameworks don’t support time. Yet, time is a crucial factor when attempting to control synchronization between multimedia entities, designing presentation and expressing temporal relationships in general. We solicit contributions that investigate temporal relationships in hypermedia and explore ways of incorporating time into hypermedia frameworks.

Hypermedia Systems and Structures

Chair: Kenneth Anderson, University of Colorado.
Co-chair: Niels Olof Bouvin, Aarhus University.
The World Wide Web, although the most popular, is not the only hypermedia system that allows structuring and browsing of information. A variety of other systems exist, that expose possibilities far beyond the web as we know it. The possibilities of these systems are due to -among other- their architectural characteristics and conceptual foundations. We seek submissions that present innovative hypermedia systems, improve the architecture and the conceptual foundations of systems, outline approaches that facilitate openness and enable distribution, introduce new modelling primitives and in general attempt to make systems a more adequate vehicle for solving structuring problems.


Papers about all aspects of hypertext and hypermedia are welcome, whether or not they fit one or more of the above themes.


Submissions are invited for full or short papers, hypertexts, posters, demonstrations, doctoral consortium proposals and workshops. Members of the program committee will review all contributions. Full papers should be between 8-10 pages long and short papers should not exceed 3 pages when printed using the official ACM templates ( Papers must be submitted electronically via the submission web page.

The conference will take place in the Dorint Hotel Salzburg. The architect Johannes Spalt has designed the hotel and it is located within walking distance from the heart of the historic old town of Salzburg (15 minutes).
Salzburg is one of Austria’s most beautiful and historic cities. From the Hohen-Salzburg Fortress (built in 1077) overlooking the city to the Bishopric Residence of the 16th century to the famous Hellbrunn Palace of the 17th century, Salzburg is a city full of awe-inspiring sights. Salzburg was awarded World Cultural Heritage status by UNESCO in 1997. Conference participants will have plenty of opportunity to enjoy the city during their stay.
