We invite submissions of research papers for presentation at NRAC 2009, 
The IJCAI-09 Workshop on Nonmonotonic Reasoning, Action and Change. NRAC 
2009 is a one-day workshop to be held in Pasadena, California as part of 
the International Joint Conference on Artificial Intelligence (IJCAI-09) 
workshop program (July 11-13).

Workshop Aims

An intelligent agent exploring a rich, dynamic world, needs cognitive 
capabilities in addition to basic functionalities for perception and 
reaction. The abilities to reason nonmonotonically, to reason about 
actions, and to change one's beliefs, have been identified as 
fundamental high-level cognitive functions necessary for common sense. 
Research in all three areas has made significant progress during the 
last two decades of the past century. It is, however, crucial to bear in 
mind the common goal of designing intelligent agents. Researchers should 
be aware of advances in all three fields since often advances in one 
field can be translated into advances in another. Many deep 
relationships have already been established between the three areas and 
the primary aim of this workshop is to further promote this 
cross-fertilization. A closer look at recent developments in the three 
fields reveals just how fruitful such cross-fertilization can be.

Comparing and contrasting our current formalisms for Nonmonotonic 
Reasoning, Reasoning about Action and Belief Revision helps identify the 
strengths and weaknesses of the various methods available. It is an 
important activity that allows researchers to evaluate the 
state-of-the-art. Indeed a significant advantage of using logical 
formalisms as representation schemes is that they facilitate the 
evaluation process. Moreover, following the initial success, more 
complex real-world applications are now within grasp. An 
implementational testbed is a primary means by which existing theories 
of nonmonotonic reasoning, action, and change are evaluated. 
Experimentation with prototype implementations not only helps to 
identify obstacles that arise in transforming theoretical solutions into 
operational solutions, but also highlights the need for the improvement 
of existing formal integrative frameworks for intelligent agents at the 
ontological level.

For the purpose of developing practical solutions to real-world 
problems, some obvious questions arise: What nonmonotonic logics and 
what theories of action and change have been implemented? Which ones are 
implementable? What can be learned from existing applications? What is 
needed to improve their scope and performance?

Despite the progress over the last few years, these questions and other 
related problems for theories of nonmonotonic reasoning, action, and 
change, still remain open. We hope to explore new approaches to these 
problems during the workshop.

This workshop will bring together researchers from all three areas with 
the aim to:

Compare and evaluate existing formalisms.
* Report on new developments and innovations.
* Identify new open problems in all three areas.
* Identify possibilities of solution transferral between the areas.
* Identify important challenges for the advancement of the areas.

Format of the Workshop

Like previous NRAC workshops, we hope NRAC 2009 to be a highly 
participatory and discussion-oriented forum. The day will begin with a 
distinguished invited speaker, and will conclude with a panel on the hot 
issues identified during the day. Authors of accepted papers will 
present their work, with ample time for discussion.

A complete program will be made available as soon as a final decision on 
accepted papers has been made.

Registration and Participation

Registration for NRAC 2009 is managed by IJCAI. Forms and Information on 
registration, pricing, travel and accommodation are available on the 
IJCAI-09 website. Participants are strongly urged to register as soon as 
possible to take advantage of discounted registration fees and to secure
