NMR 2023

21st International Workshop on Nonmonotonic Reasoning

September 2-4, 2023, Rhodes, Greece
Co-located with KR 2023

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 (KR), including belief revision, uncertain reasoning, reasoning about actions, planning, logic programming, preferences, argumentation, causality, and many other related topics including systems and applications. Visit also the general NMR webpage.

NMR has a long history - it started in 1984 and, up until 2020, was held every two years. Recent previous NMR workshops were held in Haifa (2022), Hanoi (virtually) (2021), Rhodes (virtually) (2020), Tempe (2018), Cape Town (2016), Vienna (2014), Rome (2012), Toronto (2010), and Sydney (2008).

NMR 2023 is part of the 20th International Conference on Principles of Knowledge Representation and Reasoning (KR 2023).

Aims and Scope

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 addressing benchmark issues. The workshop will be structured by topical sessions fitting to the scopes of accepted papers. Workshop activities will include invited talks and presentations of technical papers.

Submission Details

There are two types of submissions:

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.
