KR 2010: Twelfth International Conference on Principles of Knowledge Representation and Reasoning
Toronto, Canada, May 9-13, 2010

Collocated with AAMAS-10, NMR-10, ICAPS-10, FOIS-10 (all in Toronto) and DL 2010 (in Waterloo, Canada)

Knowledge Representation and Reasoning (KR&R) is a vibrant and exciting field of human endeavour. KR&R techniques are key drivers of innovation in computer science, and they have led to significant advances in practical applications in a wide range of areas from Artificial Intelligence to Software Engineering.

Explicit representations of knowledge manipulated by reasoning engines are an integral and crucial component of intelligent systems. Semantic web technologies, the design of software agents and bio-Informatics technologies, in particular, provide significant challenges for KR&R.

We intend KR2010 to be a forum for the exchange of new ideas, issues, and results among the community of researchers in the principles and practices of KR&R systems. We encourage papers presenting substantial new results in the principles of KR&R systems that clearly contribute to the formal foundations or show the applicability of the results to implemented or implementable systems. We also encourage "reports from the field" of applications, experiments, developments, and tests. Such papers should be explicitly identified as reports from the field by the authors, to ensure appropriate reviewing, and must include a section on evaluation.

For the first time, KR will be collocated with AAMAS, and a joint technical session is planned. We thus encourage papers that are relevant to both KR&R and Multi Agent Systems.

As in KR 2008, we will run a Doctoral Consortium to introduce students to senior researchers with similar research interests. Participating students will be able to apply for grants to partly cover their travel expenses. For more information, visit Doctoral Consortium Web page.

A paper must be first registered with a title, abstract, and author information by November 20, 2009, and the PDF file of the paper must be uploaded by November 30, 2009. The final paper acceptance notifications will be sent out by January 17. There is no author rebuttal to reviews. However, if a reviewer considers that a clarification about the paper is needed, a request for clarifications will be sent to the corresponding author by email, and the authors will have at least 72 hours to respond to such requests. Accepted papers will be allowed 11 pages in the conference proceedings.
