* Apologies if you receive multiple copies of this call * ======================================================================== Call for Papers (Deadline Extended) NMR 2023 September 2-4, 2023 Rhodes, Greece Co-located with KR 2023 * Deadlines: 9 June & 16 June 2023* ======================================================================== The 21st International Workshop on Nonmonotonic Reasoning (NMR) http://nmr.krportal.org/2023/ September 2-4, 2023, Rhodes, Greece ======================================================================== NMR 2023 will be co-located with the 20th International Conference on Principles of Knowledge Representation and Reasoning (KR2023), https://kr.org/KR2023/. NMR is the premier forum for results in the area of nonmonotonic reasoning. Its aim is to bring together active researchers in this broad field within knowledge representation and reasoning (KRR), including belief revision, uncertain reasoning, reasoning about actions, planning, logic programming, preferences, deontic reasoning, argumentation, causality, and many other related topics including systems and applications (see NMR page, https://nmr.cs.tu-dortmund.de/). NMR has a long history - it started in 1984 and has been held every two years until 2020 and then every year. Recent previous NMR workshops were held in Haifa (2022), Hanoi (virtual, 2021), in Rhodes (virtual, 2020), Tempe (2018) and Cape Town (2016). Since 2020 NMR is being held annually. NMR workshops are usually co-located with the KR conferences (kr.org). As in previous editions, NMR 2023 aims to foster connections between the different subareas of nonmonotonic reasoning and provide a forum for emerging topics. We especially invite papers on systems and applications, as well as position papers and papers addressing benchmark issues. The workshop will be structured by topical sessions fitting to the scopes of accepted papers. The workshop will be held in Rhodes, Greece, in September 2-4, 2023. Workshop activities will include invited talks and presentations of technical papers. -- Invited Speakers -- * Diego Calvanese Free University of Bozen-Bolzano, Italy * Juha Kontinen University of Helsinki, Finland * Anni-Yasmin Turhan Dresden University of Technology, Germany The talk by Anni-Yasmin Turhan is a joint keynote with DL 2023. -- Submission Information -- There are two types of submissions: ** Full papers ** Full papers should be at most 10 pages including references, figures and appendices, if any.

In the same vein, papers under review for other conferences can be submitted with a similar indication on their front page. ** Extended Abstracts ** Extended abstracts should be at most 3 pages. The abstracts should introduce work that has recently been published or is under review, or ongoing research at an advanced stage. We highly encourage attaching to the submission a preprint/postprint or a technical report. Such extra material will be read at the discretion of the reviewers. Submitting already published material may require a permission by the copyright holder. All submissions should be formatted in CEUR style (2-column style) without enabled header and footer. The author kit can be found at http://ceur-ws.org/Vol-XXX/CEURART.zip. Papers must be submitted in PDF only. Submission will be through the EasyChair conference system.

The copyright of papers remains with the authors. -- Student Grants -- A limited number of student grants will be made available, to support the students attending NMR 2023. Preference will be given to students that are going to present a paper at NMR and with limited access to funding. Details will be given on the NMR website. -- Important Dates -- All dates are 'Anywhere on Earth', namely 23:59 UTC-12. * Paper registration deadline: 9 June 2023 * Paper submission deadline: 16 June 2023 * Notification to authors: 17 July 2023 * Camera-ready version: 4 August 2023 * Workshop dates: 2-4 September 2023 -- Workshop Co-Chairs -- * Kai Sauerwald, FernUniversität in Hagen, Germany * Matthias Thimm, FernUniversität in Hagen, Germany -- Further Information -- Please visit the workshop website (http://nmr.krportal.org/2023/) for further information and regular updates.
