The Special Track on Uncertain Reasoning (UR) is the oldest track in FLAIRS conferences, running annually since 1996. The UR'2011 Special Track at the 24th International Florida Artificial Intelligence Research Society Conference (FLAIRS-24) is the 16th in the series. As the past tracks, UR'2011 seeks to bring together researchers working on broad issues related to reasoning under uncertainty.

All accepted papers will be published as FLAIRS proceedings by the AAAI. As in previous years, our goal is to publish a selection of the best papers in a special issue of the IJAR (The International Journal of Approximate Reasoning).

Call For Papers

Many problems in AI (in reasoning, planning, learning, perception and robotics) require the agent to operate with incomplete or uncertain information. The objective of this track is to present and discuss a broad and diverse range of current work on uncertain reasoning, including theoretical and applied research based on different paradigms. We hope that the variety and richness of this track will help to promote cross fertilization among the different approaches for uncertain reasoning, and in this way foster the development of new ideas and paradigms.

The Special Track on Uncertain Reasoning (UR) is the oldest track in FLAIRS conferences, running annually since 1996. The UR'201 Special Track at the 24th International Florida Artificial Intelligence Research Society Conference (FLAIRS-24) is the 16th in the series. As the past tracks, UR'2011 seeks to bring together researchers working on broad issues related to reasoning under uncertainty.

Papers on all aspects of uncertain reasoning are invited. Papers of particular interest include, but are not limited to:

• Uncertain reasoning formalisms, calculi and methodologies
• Reasoning with probability, possibility, fuzzy logic, belief function, vagueness, granularity, rough sets, and probability logics
• Modeling and reasoning using imprecise and indeterminate information, such as: Choquet capacities, comparative orderings, convex sets of measures, and interval-valued probabilities
• Exact, approximate and qualitative uncertain reasoning
• Graphical models of uncertainty
• Multi-agent uncertain reasoning and decision making
• Decision-theoretic planning and Markov decision process
• Temporal reasoning and uncertainty
• Nonmonotonic and conditional Logics
• Argumentation
• Belief change and Merging
• Similarity-based reasoning
• Construction of models from elicitation, data mining and knowledge discovery
• Uncertain reasoning in information retrieval, filtering, fusion, diagnosis, prediction, situation assessment
• Practical applications of uncertain reasoning

Travel Information

FLAIRS 2011 will be held in West Palm Beach, Florida. Additional information on the conference location and travel planning can be found at http://www.flairs-24.info/.

The papers should be original work (i.e., not submitted, in submission, or submitted to another conference while in review).

Interested authors should format their papers according to AAAI formatting guidelines. For FLAIRS-24, the 2011 conference, the reviewing is a double blind process. Fake author names and affiliations must be used on submitted papers to provide double-blind reviewing. The papers will be reviewed by at least three reviewers. Papers must be submitted as PDF through the EasyChair conference system (http://ww.easychair.org/conferences/?conf=flairs24), which can also be accessed through the main conference web site (http://www.flairs-24.info). Do not use a fake name for your EasyChair login - your EasyChair account information is hidden from reviewers.

Authors should indicate the special track "Uncertain Reasoning" for submissions.

The proceedings of FLAIRS-24 will be published by the AAAI. Authors of accepted papers will be required to sign a form transferring copyright of their contribution to AAAI.

An author of each accepted paper is required to register, attend, and present the paper at FLAIRS-24.

Co-Chair submission policy

As for the general and other tracks, there is a specific procedure for reviewing the papers that might be submitted by one of the UR special track co-chairs.

One of the co-chair suggests 5 members from the UR PC list as possible reviewers. The FLAIRS-24 program co-chairs will pick reviewers from the 5 designated PC members and FLAIRS PC members; the FLAIRS-24 program co-chairs will also add 2 additional reviewers issued from the general PC.

Any submission from the UR co-chairs will not be considered for the intented special issue of the best UR papers.

Submission of papers.	November 22, 2010
Notification of acceptance.	January 21, 2011
Camera-ready versions due.	February 21, 2011
FLAIRS-24 conference held.	May 18-20, 2011

Professor Robert Holte of the Computing Science Department at the University of Alberta is a well-known member of the international machine learning research community, former editor-in-chief of a leading international journal in this area ("Machine Learning"), and co-founder and former director of the world-renowned Alberta Ingenuity Centre for Machine Learning (AICML). In addition to machine learning he undertakes research in single-agent heuristic search (pathfinding): in particular, the use of automatic abstraction techniques to speed up search. His main scientific contributions are his seminal works on the performance of very simple classification rules, the "cost curve" method for evaluating classifiers when misclassification costs or the class distribution are unknown, several key advances in single-agent search, and his contributions to the Computer Poker Research Group at the University of Alberta. Much of his current research combines his two research interests by applying learning in the context of game-playing (e.g. opponent modelling in poker) or search (e.g. using learning to create search heuristics). He has over 90 scientific papers to his credit, covering both pure and applied research, and has served on the steering committee or program committee of numerous major international Artificial Intelligence conferences.
