This newsletter contains the description of a special session organized at
NMR-2000 on UNCERTAINTY FRAMEWORKS IN NMR. This session is made of 11
papers which are available (together with their abstracts) at
http://www.ida.liu.se/ext/etai/ufn/received/sframe.html .

All these papers are open to discussion. If you want to act as a
discussant, please send your contribution to benferhat@irit.fr or
prade@irit.fr.

Many approaches have been developed for reasoning under incomplete information
with uncertain rules having exceptions. Some of them are symbolic and based
on a
logical framework or on logic programming; others are more numerically oriented
and make use of probabilities, qualitative or quantitative possibilities, or of
mathematically more general uncertainty frameworks such as belief and
plausibility
functions, or upper and lower probabilities. The session will especially
welcome
papers contributing to a cross-fertilization of ideas or tools coming from
symbolic
methods (normative frameworks, bilattices,...) and from numerical approaches
(independence, graphical representation, conditioning,...) for NMR and revision
purposes. Papers addressing problems related to the practical use and
applications
of probabilistic, possibilistic and other uncertainty frameworks in NMR are
also
expected, as well as NMR issues in reasoning about goals and preferences, or
about obligations and permissions.
