International Symposium on Logical Formalization of Commonsense Reasoning


AAAI Spring Symposium Series


March 24-26, 2003

Stanford University

California, USA

One of the major long-term goals of artificial intelligence is to endow computers with commonsense reasoning capabilities. Although we know how to design and build systems that excel at certain bounded or mechanical tasks which humans find difficult, such as playing chess, we have little idea how to construct computer systems that do well at commonsense tasks which are easy for humans. Formalizing commonsense reasoning using logic-based approaches will be the focus of the symposium. Logic is a powerful modelling tool. Emphasis will be placed on representation rather than algorithms, and on formal rather than informal methods.

Commonsense reasoning is required in a wide variety of systems from autonomous lawn mowers to deep space probes. Systems that exhibit commonsense have to possess robust solutions to fundamental problems in knowledge representation. For example, an essential feature of commonsense reasoning is that it must deal with incomplete and uncertain information in dynamic environments responsively and appropriately. Furthermore, commonsense systems typically need to communicate with other systems in meaningful ways so ontological issues naturally arise.

Topics of interest will include:


The symposium will take place over three days and involve Invited Presentations from pioneers in the field, lively panel discussions, and paper presentations. If you would like to attend the symposium please send an expression of interest outlining your reasons to one of the Symposium Chairs.
