Special focus: probabilistic logics and probabilistic networks

5-7 September 2007
Keynes College Lecture Room 2, University of Kent, Canterbury, UK

There are a plethora of views as to the relationship between probability and logic and a panoply of proposals for combining the two. In particular, probabilistic logics offer formal combinations of probability and logic – often, however, at the expense of perspicuity and tractability. The question arises as to whether probabilistic networks might be used to render probabilistic logics more comprehensible and computationally feasible.

In this workshop we aim to bring researchers from a variety of disciplines together to assess the prospects of applying probabilistic networks to probabilistic logics, and more generally to elucidate the relationship between probability and logic. We hope that the themes of the workshop will be of interest to mathematicians, logicians, philosophers, computer scientists, statisticians, psychologists and engineers, for example.

Invited speakers include:
Gert de Cooman, Fabio Cozman, Pedro Domingos, Lise Getoor, Stephan Hartmann, Colin Howson, Manfred Jaeger, David Makinson, Jeff Paris. Linda van der Gaag can no longer attend because of illness.

We invite submissions of two-page extended abstracts of talks for presentation at the workshop.

There will also be a special issue of the Journal of Applied Logic devoted to the themes of this workshop. We invite submission of papers to this volume.

Example Questions

  • How is probability related to logic?
  • Should probability and logic be combined at all?
  • How can probabilistic networks be used to simplify probabilistic logics?
  • Which interpretations of probability best fit its application to probabilistic logic?
  • What are the potential applications of probabilistic logic?
  • To what extent do different applications demand different probabilistic logics?
  • Which probabilistic logics offer the most potential?
  • Do probabilistic logics require precise or imprecise probabilities?
