Hypertext 2009
The Twentieth ACM Conference on Hypertext and Hypermedia

June 29th - July 1st, 2009, Torino, Italy

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.

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  


* Peter Brusilovsky, University of Pittsburgh (USA)
* Cristina Gena, University of Torino (Italy)

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  
  * 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  
  * 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 ( 
proceedings-templates) and submitted via EasyChair (http:// 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 to by e-mail to  
Giancarlo Ruffo, Demo Chair <[log in to unmask]>.

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. Acceptance of workshop  
proposals will be based on the organizer's experience and background  
in the topic, and on the relevance of the subject matter w.r.t. the  
topics addressed in the main conference.
