Uncertainty Frameworks in Nonmonotonic Reasoning

Special  Session at
9th Intl. Workshop on Non-Monotonic Reasoning NMR'2002

April 19-21, 2002, Toulouse, France
(Collocated with KR'2002, April 22-25)


The abilities to handle uncertain information and to reason nonmonotonically from incomplete knowledge are crucial features of an intelligent behaviour in a complex and dynamic environment. This is why reasoning under uncertainty and nonmonotonic reasoning have established themselves as major research areas in Artificial Intelligence during the recent decades. The aim of this special session (or mini-workshop) at NMR'2002 is to bring together researchers working in the intersection of both fields. We address people working on traditional nonmonotonic reasoning tasks using uncertainty reasoning tools as well as people from uncertainty management approaching nonmonotonic aspects of their models. We will especially welcome papers that explore the relationship between different approaches and that improve understanding and cross-fertilization of different techniques from both fields.

This is the second meeting on uncertainty frameworks in nonmonotonic reasoning. The first meeting was held as a special session at NMR'2000, April 9-11, 2000, Breckenridge, Colorado, USA (collocated with KR'2000, April 12-15).

The main focus of the meeting is in nonmonotonic aspects related to the following topics:

Some perspectives of interest are:


We invite submissions on the themes listed above (but not limited to). Submitted papers should not exceed 12 pages (excluding title page and references) of standard LaTeX 12pt article format. Work reported should not have appeared elsewhere.

We strongly encourage electronic submission of papers in postscript or pdf format. To submit a paper electronically, send an email message to both of the Program Co-Chairs (see email addresses below) that includes the following information:

Authors unable to submit papers electronically should send the above four items by email to both of the Program Co-Chairs and three copies of the complete paper by surface mail to one of the Program Co-Chairs (see addresses below).

Informal proceedings containing accepted papers will be distributed at the meeting; post-workshop (formal) proceedings will be announced later.


Submission of papers: February 14, 2002
Acceptance decision by: March 1, 2002
Camera ready copy due: March 18, 2002
Special Session date: April 20, 2002


Please note that registration for NMR'2002 is a necessary condition for participating the meeting.
