Hi all,

Apologies for cross-postings.
NOTE: Think you missed the deadline, but have a good idea? We have moved our deadlines closer to the conference for those last minute, fresh ideas.  You have a week left!
21st ACM Conference on Hypertext and Hypermedia (ACM Special Interest Group on Hypertext, Hypermedia and the Web)
Place: Victoria University at the University of Toronto, Toronto, Ontario, Canada
Time:  June 13-16, 2010
New Deadlines:
1) Papers and Workshops
Deadline for papers:  February 14th
Notification to authors: March 22nd
2) Posters
Deadline for posters: March 29th
Notification to authors: April 15th
Camera-ready copy (all accepted submissions):  May 1st (All deadlines: midnight, Hawaii Standard Time)
The ACM Hypertext Conference is the main venue for high quality peer-reviewed, double-blind research on "linking" and interconnectivity. The Web, the Semantic Web, Web 2.0 and Social Networks are all manifestations of the success of the link concept.
Technical Tracks:
Hypertext 2010 will consist of three autonomous tracks, each with its own Track Program Committee. These Tracks are intended to represent the spectrum of Hypertext. If you cannot figure out where you fit, submit to the best fitting track or send us email.
Track 1. Social Computing
Chair:  Anabel Quaan-Haase, University of Western Ontario This track invites papers investigating social processes and practices in Hypermedia and Web 2.0 environments. These include tagging, filtering, voting, editing, trusting, and rating. These social processes result in many types of links between texts, users, concepts, pages, etc. We want to better understand the processes and practices themselves as well as the social, political, and semantic networks that result over time.
Track 2. Adaptive Hypermedia and Applications
Chair:  Richard Kopak, University of British Columbia This track invites papers reporting on theoretical, empirical, and methodological studies on adaptive hypermedia, including the application of adaptive hypermedia such as self organizing in varying domains and contexts.
The scope includes all forms of Web and Hypermedia systems, including user modeling, recommender systems, and e-learning, as well as components of resulting systems (e.g, navigation).
Track 3. - Hypertext in Context
Mark Bernstein, Eastgate Systems, Inc.
David Millard, University of Southampton, UK
Hypertext tools are indispensable for e-learning and m-learning, and  teaching Hypertext as a discipline in its own right -- including  literary fiction, new scholarship and digital media -- plays a growing  role in education.
This track
targets hypertext as both a tool and a  discipline, as well as focusing on the use of spatial hypertext and  Web 2.0 applications such as blogs, wikis and e-portfolios. We hope to  highlight our understanding of links as a new component of writing and  communication, and to increase our understanding of the way that they  are used in multiple domains such as education, research, journalism, and literature.
Types of Submission
1) Papers
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 include:
a) regular research papers (max 10 pages) discussing mature work, and
b) short papers (max 5 pages) describing preliminary results of on-going work or novel thought-provoking ideas.
2) Posters and Demos
Technical demonstration of new tools and innovative applications of hypertext are solicited, as well as research at a preliminary stage.  Submissions may
a) Posters: (max 2 page) offer researchers a unique opportunity to present late-breaking results, significant work in progress, or research that is best communicated in an interactive or graphical format. Poster submissions are welcomed in areas related to any of the three tracks. Please note, however, that posters describing work at the proposal stage will not be accepted.
b) Demos:  (max 1 page) should describe the system and include a list of any required supporting equipment. We assume that most equipment will be supplied by the demonstrator.
Poster and demos presentations further provide researchers with an opportunity to obtain direct feedback about their work from a wide audience during the poster session.
c) Workshops
At least two workshops will be held on the first day of the conference, Sunday, June14th before the main conference. The purpose of the workshops is to provide a more informal setting for the exchange of ideas on a focused topic and suggest directions for future research. As such, they also offer a good opportunity for 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. See the Track descriptions for ideas.
All submissions should be formatted according to the official ACM SIG proceedings template
(http://www.acm.org/sigs/publications/proceedings-templates) and submitted via EasyChair (http://www.easychair.org/conferences/?conf=ht2010).
Accepted papers will appear in the Hypertext 2010 Conference Proceedings and also be available through the ACM Digital Library.
