Social Linking Track at Hypertext 2008: ­ the Nineteenth ACM
Conference on Hypertext and Hypermedia

June 19th-21st 2008, Pittsburgh, PA, USA

*** Second Call for Papers (submission deadline: February 11th 2008)

The ACM Conference on Hypertext and Hypermedia is the acknowledged
venue for high quality peer-reviewed research on linking. The web, the
semantic web and the Web 2.0 are all manifestations of the success of
the link. The Hypertext Conference provides the forum for research
that considers links, their semantics, their presentation, the
applications they have been put to, the knowledge that can be derived
from their analysis and their effect of society. If information is
connected, then the connection is called a link, and the Hypertext
Conference is concerned with all research concerning links. HT08 will
consist of four independent tracks, each with its own track committee:
Information Linking and Organization; Applications of  Hypertext;
Hypertext, Culture, and Communication; and Social Linking, to which we
call your attention.

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:

* Design of collaborative annotation mechanisms
* Critical mass and incentives of social participation (e.g. games)
* User interfaces for collaborative annotation
* Applications to search, retrieval, recommendation, and navigation
* Explicit vs. inferred social links (e.g. mining query logs)
* Integration with content-based systems  (e.g. linking in blogs)
* Socially induced measures of similarity, relatedness, or distance
* Co-evolution of social, information, and semantic networks
* Analysis of structure and dynamics of social information networks
* 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
* Robustness against spam and other forms of social abuse

Details on the submission format and procedure are available at the
HT2008 submission page (
Accepted papers will appear in the formal Conference Proceedings,
published by ACM. All material will be available through the ACM
Digital Library.

*** Technical Paper Stream

February 11th 2008 submission deadline
March 21st 2008 authors informed of results of reviewing
April 4th 2008 final Papers to ACM

Full Papers:
Full technical papers (10 pages) should present significant scientific
advances that are at a mature stage of development. We are looking for
full papers that present relevant contributions to research,
development, and practice in the area of hypertext and hypermedia. We
are also interested in survey papers which present an authoritative
and original perspective on an area of interest.

Short Papers:
Short papers (5 pages) should present interesting recent results or
novel thought-provoking ideas that are not quite ready for a regular
full-length paper, or where the research has limited scope or the
results have lesser significance.

*** Posters and Demonstrations

March 28th 2008 submission deadline
April 9th 2008 committee decisions to authors
April 16th 2008 final copy to ACM

Poster presentations and demonstrations (2 pages in the proceedings)
are solicited, which present new ideas, generate interest in a
research area, or describe or demonstrate useful or interesting work
that is not substantial enough for a technical paper presentation.

*** Location

ACM Hypertext 2008 will take place in Pittsburgh, Pennsylvania, ranked
#1 Most  Livable City in America. It is co-located and scheduled
directly after ACM/IEEE Joint Conference on Digital Libraries
( The two conferences will meet again in
Pittsburgh, 10 years years after ACM Hypertext 1998 and ACM Digital
Libraries 1998 were last co-located there. In 2008, both conferences
are being hosted by the School of Information Sciences at the
University of Pittsburgh (  The Pittsburgh
area is home to more than 25 colleges and universities, resulting in a
vibrant and diverse community  of learners and teachers.  The region
welcomes more than 10 million  visitors each year, who enjoy amenities
and cultural attractions including  the world-class Carnegie Museums,
the outstanding Pittsburgh Symphony Orchestra and the decades-long
tradition of major league sports!  Pittsburgh  is centrally located,
being within 90 minutes flying time of the country's  major
metropolitan areas.  While being challenged by the presentations  at
Hypertext 2008, don't miss an opportunity to sample the museums,  the
performing arts organizations and the city's charming and diverse
