20th Qualitative Reasoning Workshop
  www.cs.dartmouth.edu/~qr06
  Dartmouth College, Hanover, NH, USA
  July 10-12, 2006

The world is full of physical systems about which we have incomplete,
qualitative knowledge.  Humans are amazingly effective at working with
such knowledge, and many science, engineering, and educational
applications could benefit greatly from similar capabilities.  In
seeking to understand, develop, and exploit the ability to reason
qualitatively, the QR community pursues research at the interface of
Artificial Intelligence, Cognitive Science, Engineering, and
Science. Some QR researchers study, from a cognitive modeling
perspective, how humans represent and use incomplete knowledge about
physical systems.  Others develop algorithms and systems for
constructing, simulating, and applying qualitative and
semi-quantitative models.  Still others exploit these insights to
develop powerful methods for system modeling, explanation, diagnosis,
and design, and in applications in science, engineering, and
education.

The 20th International Workshop on Qualitative Reasoning provides a
forum bringing together researchers from all these perspectives.  The
Workshop will be held at Dartmouth College, Hanover, New Hampshire,
from July 10 through 12, 2006.


Important Dates
* Submission: March 9, 2006
* Notification: April 24, 2006

  references) must be submitted by e-mail to qr06@cs.dartmouth.edu by
  March 9, 2006.
* Poster.
  A PDF file of the poster paper not to exceed 2000 words (excluding
  references) must be submitted by e-mail to qr06@cs.dartmouth.edu by
  March 9, 2006.
* Review Process.
  Both papers and posters will be selected according to their quality,
  significance, originality, and potential to generate
  discussion. Each contribution will be reviewed by at least two
  referees from the QR-06 Program Committee.
* Submission to Conferences or Journals. 
  The accepted papers will be published as a collection of Working
  papers. As QR-06 is a workshop, not a conference, submission of the
  same paper to conferences (e.g., AAAI-06) or journals is acceptable.
* Format.
  Papers should be formatted according to the AAAI-06 guidelines,
  available from www.aaai.org, and must be in PDF format.
* Additional participants. 
  People who wish to receive an invitation to attend the workshop
  without submitting a paper or a poster should send a request to
  qr06@cs.dartmouth.edu.
