We invite submissions for presentation at Commonsense'07, the 8th
International Symposium on Logical Formalizations of Commonsense
Reasoning, to be held as part of the AAAI Spring Symposium Series, March
26-28 2007, at Stanford University, California, USA.

One of the major long-term goals of AI is to endow computers with common
sense, and one approach to this goal is to formalize commonsense
reasoning using mathematical logic. This is the focus of this symposium.
The challenges to creating such a formalization include the accumulation
of large amounts of knowledge about our everday world, the
representation of this knowledge in suitable formal languages, the
integration of different representations in a coherent way, and the
development of explicit reasoning methods that use these
representations. Specific topics of interest include:

- change, action, and causality
- ontologies, including space, time, shape, and matter
- levels of granularity of ontology and reasoning
- large commonsense knowledge bases
- axiomatizations of benchmark commonsense problems
- exploration of new commmonsense domains in a preformal way
- FLAGS (\Recent) RFC822.SIZE 6071)
  nonmonotonic reasoning
- formal models of probabilistic reasoning
- formal theories of context
- mental attitudes
- belief change, update, and revision
- cognitive robotics
- reasoning about multi-agent systems
- aspects of commonsense reasoning applicable to the Semantic Web
- applications of formal representations to applications
- other mathematical tools for capturing commonsense reasoning

The focus of the symposium is on formal representation rather than on
algorithms. While mathematical logic is expected to be the primary
lingua franca of the symposium, we also welcome papers using a rigorous
but non-logic-based representation of commonsense domains. Technical
papers offering new results in the area are especially welcome;
object-level theories as opposed to meta-level results are preferred.
However, survey papers, papers studying the relationship between
different approaches, and papers on methodological issues such as theory
evaluation, are also encouraged.

We are pleased to be able to hold this symposium as a special event in
honor of John McCarthy's 80th year. John McCarthy is, of course, the
father of formal commonsense reasoning, and submissions which celebrate
his immense contribution to the field are especially welcome.

Papers or extended abstracts of no more than 6 pages should be submitted
as email attachments to [email protected] (PDF format) by October
6, 2006. All submissions will be reviewed by the program committee as
listed on the Commonsense'07 web site (URL below). The symposium will be
co-chaired by

- Eyal Amir, University of Illinois
- Vladimir Lifschitz, University of Texas at Austin
- Rob Miller, University College London
