Final Call For Papers

Hypertext 2009
The Twentieth ACM Conference on Hypertext and Hypermedia

Torino, Italy, June 29 - July 1, 2009


The ACM Hypertext Conference is the main venue for high quality 
peer-reviewed research on "linking." The Web, the Semantic Web, the Web 
2.0, and Social Networks are all manifestations of the success of the 
link. The Hypertext Conference provides the forum for all research 
concerning links: their semantics, their presentation, the applications, 
as well as the knowledge that can be derived from their analysis and 
their effects on society.

Hypertext 2008, held in Pittsburgh, was a real success. The number of 
submissions and attendees was up, a successful Student Research 
Competition took place, and a rejuvenated social linking track added new 
ideas and connections to the traditional core of the conference.


* Technical tracks paper submission deadline: February 2nd, 2009
* Notification to authors: March 16th, 2009
* Camera-ready (final papers to ACM): April 6th, 2009


Hypertext 2009 will be held from June 29th to July 1st at the Villa 
Gualino Convention Center, on the hills overlooking Torino.

The capital of the Piedmont region, Torino lies at the foot of the Alps, 
the majestic mountains that hosted the 2006 Winter Olympics. First the 
capital of the Kingdom of Italy, then one of the European centers of 
baroque, today Torino is a dynamic city known for its industry, art and 
culture, sports, research and education, and cuisine.

The timing of Hypertext 2009 provides an excellent opportunity to visit 
Italy in conjunction with the International Conference on User Modeling, 
Adaptation, and Personalization in Trento (UMAP 2009 -, and the International Workshop and Conference on 
Network Science in Venice (NetSci 2009 -


Hypertext 2009 will feature two stellar keynote speakers: Lada Adamic 
(University of Michigan) is a noted scholar of social networking and the 
winner of the 2008 Engelbart Award; Ricardo Baeza-Yates is 
Vice-President of Yahoo! Research for Europe and Latin America, leading 
the labs in Spain, Chile, and Israel.

The attendees of Hypertext 2009 will also have a chance to experiment 
with applications mixing real-world data and on-line data. We will 
deploy active RFID tags in the badges of volunteers and track the 
real-time relations of physical proximity between the attendees. The 
data collection and visualization system will be provided by the 
SocioPatterns project ( and will expose API 
methods that allow developers to mash up real-world links between the 
attendees with other types of linking information from the Web.

In the conference technical program, professionals from academia, 
industry, and the media will present innovative ideas and tools 
exploiting the broad range of links increasingly connecting people, 
information, communities, and structures. Research topics will be 
organized into three tracks:

Track 1. Information Structure and Presentation (Chairs: Peter 
Brusilovsky and Cristina Gena)
Track 2. People, Resources, and Annotations (Chairs: Andreas Hotho and 
Vittorio Loreto)
Track 3. Hypertext and Community (Chairs: Mark Bernstein and Antonio Pizzo)


The information structure and presentation track represents a multitude 
of topics, which were traditionally represented at ACM Hypertext 
Conferences. The track program targets formal study of scholarly, 
structural, sculptural, spatial, open, dynamic and adaptive or any other 
type of hypertext (or Web-based Information System). This track also 
focuses on how hypertext approaches and technologies can be applied to 
structure and present information in diverse domains, and how hypertext 
techniques can be exploited in classical and advanced applications. The 
aim of this track is to bring researchers together to discuss models, 
architecture, applications, properties, or theory in general, about 
hypertext and hypermedia. Topics for consideration include:

  * Hypertext models
  * Spatial hypertext
  * Information structuring
  * Hypertext and knowledge management
  * Self-organized hypertext
  * Personal information organization
  * Intelligent hypertext and link generation
  * Navigation support
  * Open hypertext
  * Web and hypertext link analysis
  * Dynamic and adaptive hypertext
  * Hypertext and web engineering
  * Interfaces and interaction with hypertexts
  * Faceted browsing
  * Social navigation
  * Hypertexts supporting Web-based collaboration
  * Hypertext and recommender systems: the role of link in recommendations
  * Hypertext applications in everyday devices (TV, mobile phone, on 
board car service, etc.)
  * Educational hypertext and hypermedia
  * User evaluations of hypertext application
  * Hypertext and cultural heritage
  * E-books, kiosks, e-commerce, e-tourism
  * Hypertext application in medical and health systems

One of the most exciting recent developments in Web science is the rise 
of social annotation, by which users can easily markup other authors' 
resources via collaborative mechanisms such as tagging, filtering, 
voting, editing, classification, and rating. These social processes lead 
to the emergence of many types of links between texts, users, concepts, 
pages, articles, media, and so on. We welcome submissions on design, 
analysis, and modeling of information systems driven by social linking. 
Topics of interest include but are not limited to:

  * Applications to search, retrieval, recommendation, and navigation
  * Explicit vs. inferred social links (e.g. mining query logs)
  * Integration of different social networks (e.g. links between blogs 
and bookmarking systems)
  * Socially induced measures of similarity, relatedness, or distance
  * Co-evolution of social, information, and semantic networks
  * Analysis of the structure and the dynamics of social information 
  * Behavioral patterns of social linking
  * Linguistic analysis of social annotation spaces
  * Formal and generative models of social annotation
  * Unstructured vs. structured social knowledge representations
  * Implementation and scalability of social link representations
  * Automatic and user-based evaluation
  * Emergent semantics in social networks
  * Robustness against spam and other forms of social abuse
  * Design of collaborative annotation mechanisms
  * Critical mass and incentives of social participation (e.g. games)
  * User interfaces for collaborative annotation

The Hypertext and Community track will explore, examine, and reflect 
upon social cyberculture in electronic media, ranging from literary 
fiction and creative scholarship to blog and microblog networks, social 
sites, games, auctions, and markets. Topics will include:

  * Hypertext literature
  * Theory and practice of expression in wikis, weblogs, and social spaces
  * Personal journals, weblogs, and social media
  * Net art, literary hypertext, interactive fiction, and games
  * Behavioral patterns of social linking

Papers must report new results substantiated by experimentation, 
simulation, analysis, or application. Authors are invited to submit 
papers presenting original, not previously published works. Submission 
categories may include regular research papers (max 10 pages) discussing 
mature work, and short papers (max 5 pages) describing preliminary 
results of on-going work or novel thought-provoking ideas.

All submissions should be formatted according to the official ACM SIG 
proceedings template 
( and 
submitted via EasyChair 
( Authors are not 
required to anonymize submissions, but are asked to submit keywords via 
EasyChair. Accepted papers will appear in the Hypertext 2009 Conference 
Proceedings and also be available through the ACM Digital Library.


Technical demonstration of new tools and innovative applications of 
hypertext are solicited. One-page demo descriptions, including a list of 
any required supporting equipment, should be sent by e-mail to the Demo 
Chairs, Giancarlo Ruffo ([log in to unmask]) and Wouter Van den Broeck 
([log in to unmask]).

Important Demos Dates:

  * March 30th, 2009: Submission of proposals
  * April 15th, 2009: Notification to proposers
  * June 29th, 2009: Demo day


ACM Hypertext 2009 will be running at least two workshops, taking place 
on the 29th of June before the start of the main conference.  The 
purpose of the workshops is to provide a more informal setting where 
participants can exchange ideas on a focused topic and suggest 
directions for future research.  As such, they also offer a good 
opportunity for (young) researchers to present their work and to obtain 
feedback from an interested community.  Further information on accepted 
workshops will be found on the conference website.
