About the DEON conference series

The biennial International Conference on Deontic Logic and Normative Systems (DEON) conference series aims at bringing together researchers interested in the formal study of normative concepts, normative reasoning, and normative systems using methods from computer science, artificial intelligence, philosophy, linguistics, mathematics, and law. The series particularly aims at fostering interdisciplinary collaboration that combines methods from these various fields.

Topics include, but are not limited to, the investigation of normative reasoning, concepts, and systems in relation to:

  • agency and action
  • argumentation
  • defeasible reasoning
  • deontic modals
  • epistemic reasoning
  • explainability
  • knowledge representation
  • legal reasoning
  • multi-agent systems
  • natural language
  • norm change / revision
  • philosophy of reasons
  • policy
  • preference reasoning
  • responsibility
  • social values
  • temporal reasoning
  • trustworthy systems

We welcome submissions of both theoretical and applied research for DEON 2027, and encourage interdisciplinary work.

General theme

Normativity under Uncertainty

Normative systems are inescapably confronted with uncertainty. Agents must frequently deliberate about what ought to be done on the basis of information that is incomplete, imprecise, or conflicting, where the uncertainty may concern the facts of the case, the norms in force, the consequences of action, or the reliability of one's sources. Classical deontic logics, by contrast, typically assume consistent sets of norms and abstract away from the epistemic situation of agents.

The general theme of this edition of DEON, Normativity under Uncertainty, addresses the logical, philosophical, and computational foundations of normative reasoning once these idealizations are lifted. The aim is to investigate how central normative concepts, among them obligation, permission, responsibility, and blame, can be rigorously formalized, interpreted, and applied under diverse forms of uncertainty, including defeasible and non-monotonic inference as well as probabilistic and epistemic reasoning.

Submission details

We invite submission of original and unpublished work. Parallel submission to journals or to other conferences or workshops with published proceedings is not permitted.

Papers should be written in English.

The reviewing process for DEON 2027 is double-blind. Submissions must be anonymized (see below).

Submitted papers should not be longer than 15 pages, excluding references and technical appendix. Reviewers are not required to read the technical appendix and may choose to do so at their discretion.

LaTeX and Word templates for preparing submissions: To be announced

Papers must be submitted in PDF format via EasyChair: To be announced

Upon acceptance, final papers must be submitted as a LaTeX file together with the corresponding PDF for the camera-ready version. Converting a Word file into the required LaTeX template is the sole responsibility of the authors of the accepted paper.

Anonymization guidelines

Since DEON 2027 uses double-blind reviewing, submissions must not reveal the authors’ identities. Please ensure the following before submitting:

  • Do not include author names, affiliations, or contact details on the title page or anywhere in the paper.
  • Remove acknowledgements, funding information, and project identifiers from the submitted version; these may be added to the camera-ready version.
  • Refer to your own previous work in the third person, as you would refer to work by others. For example, write “as shown in [7]” rather than “as shown in our previous work [7]”.
  • Do not include links to non-anonymized repositories, personal web pages, or supplementary material that reveals your identity.
  • Remove identifying metadata from the PDF file.

Submissions that clearly violate these requirements may be rejected without review.

Preprints and prior dissemination

Posting a preprint of a submitted paper on a public archive such as arXiv, or presenting it at a workshop without published proceedings, is permitted and does not constitute prior publication. Authors are, however, asked not to actively advertise their submission in a way that would compromise the double-blind process during the review period. Reviewers are not expected to search for preprint versions of submissions, and inadvertent discovery of a submission’s authorship is not in itself grounds for rejection.

Policy on plagiarism and the use of LLMs

For authors. Papers containing text generated by large language models (LLMs) are not permitted. An exception is made where such text appears as the object of an experimental analysis, provided that the source model is explicitly cited. Authors may use LLMs to edit and polish text that they themselves have written. Generative AI models do not meet the criteria for authorship of scientific papers and may not be listed as authors, nor may their outputs be used as a citable source in a DEON submission.

Submissions that, in the judgement of the programme chairs, consist substantially of LLM-generated content will be desk-rejected. Where such a concern is raised, the submission will be examined independently by at least two programme chairs; a desk rejection requires their agreement. Authors will be informed of the decision and may respond to the chairs.

Any attempt at prompt injection — that is, inserting text into a paper with the intention of manipulating an LLM, for instance in order to obtain a favourable review — is strictly forbidden and will result in desk rejection.

For reviewers. Reviewers must not upload submissions, in whole or in part, to any LLM service that does not guarantee confidentiality; submissions are confidential material. Reviews must not be written by an LLM. Reviewers remain fully responsible for the entire content of their reviews, including any inaccuracies introduced by tools they may have used.

Responsibility. In submitting to DEON, authors are fully responsible for their submitted content, including avoiding plagiarism and complying with the policy above. Any allegation or violation of this policy will be investigated and, if substantiated, possible outcomes include rejection or retraction of the work.

Publication

The proceedings of the conference will be published by College Publications as an open-access book and will be available to participants during the conference.
