Belief Change


Specialized workshop in conjunction with NMR2004 (www.pims.math.ca/science/2004/NMR/papers.html)

Belief change and nonmonotonic reasoning go hand in hand. Over the years, research in belief change has taken several interesting turns and seen many novel developments. Moreover, it has allowed us to see other areas of endeavour in a new light. As a way of capturing commonsense reasoning, for instance, belief change provides a unique perspective. However, there is still much work to be done, many interesting challenges to be overcome and problems to be explored.

The specialized workshop on Belief Change is a one-day event intended to bring together researchers interested in the area of belief change, and to discuss current research, results, and problems of a theoretical, foundational or practical nature. In particular, researchers from allied fields are encouraged to submit papers and participate in the workshop. This workshop will be a part of the technical program of the tenth Nonmonotonic Reasoning Workshop (NMR-04), to be held in Whistler, BC, Canada, immediately following the KR-04 conference. The goal is to promote further development of the theory of belief change as well as connections to other research areas in nonmonotonic reasoning, knowledge representation and reasoning, and artificial intelligence.


Authors are invited to submit original papers on all aspects of belief change.

The list of topics of interest includes but is not limited to:

  • Theoretical and philosophical foundations of belief change
  • Belief merging
  • Iterated belief change
  • Non-prioritized belief change
  • Interrelations
  • Complexity of belief change operations
  • Implementations of belief change systems

We also welcome suggestions for panel discussions.

All NMR-04 subworkshops have the same submission requirements. Submissions are limited to 12 pages (excluding title page and references) of standard LaTeX 12pt article format. Send a pdf file with the submission to each of the organizers by e-mail.

Final papers, limited to 9 KR-style pages, will be distributed at the meeting along with papers from the other NMR workshops. Accepted papers will also be arranged into on-line proceedings.

The other specialized workshops that will be held at NMR-04 are:
