CALL FOR PAPERS

18th Conference on Principles of Knowledge Representation and Reasoning (KR2021)

November 6-12, 2021, Hanoi, Vietnam -> see note below about remote participation

https://kr2021.kbsg.rwth-aachen.de

Knowledge Representation and Reasoning (KR) is a well-established and lively field of research. In KR a fundamental assumption is that an agent's knowledge is explicitly represented in a declarative form, suitable for processing by dedicated reasoning engines. This assumption, that much of what an agent deals with is knowledge-based, is common in many modern intelligent systems. Consequently, KR has contributed to the theory and practice of various areas in AI, including automated planning and natural language understanding, and to fields beyond AI, including databases, verification, software engineering, and robotics. In recent years, KR has contributed also to new and emerging fields, including the semantic web, computational biology, cyber security, and the development of software agents.

The KR conference series is the leading forum for timely in-depth presentation of progress in the theory and principles underlying the representation and computational management of knowledge.

** SCOPE **

We solicit papers presenting novel results on the principles of KR that clearly contribute to the formal foundations of relevant problems or show the applicability of results to implemented or implementable systems. We also welcome papers from other areas that show clear use of, or contributions to, the principles or practice of KR.

Topics of interest include, but are not limited to:

- Applications of KR

- Argumentation

- Belief revision and update, belief merging, information fusion

- Commonsense reasoning

- Computational aspects of knowledge representation

- Concept formation, similarity-based reasoning

- Contextual reasoning

- Decision making

- Description logics

- Explanation finding, diagnosis, causal reasoning, abduction

- Geometric, spatial, and temporal reasoning

- Inconsistency- and exception-tolerant reasoning, paraconsistent logics

- KR and autonomous agents and multi-agent systems

- KR and cognitive robotics

- KR and cyber security

- KR and education

- KR and game theory

- KR and machine learning, inductive logic programming, knowledge acquisition

- KR and natural language processing and understanding

- KR and the Web, Semantic Web

- Knowledge graphs and open linked data

- Knowledge representation languages

- Logic programming, answer set programming

- Modeling and reasoning about preferences

- Multi- and order-sorted representations and reasoning

- Nonmonotonic logics, default logics, conditional logics

- Ontology formalisms and models

- Ontology-based data access, integration, and exchange

- Philosophical foundations of KR

- Qualitative reasoning, reasoning about physical systems

- Reasoning about actions and change, action languages

- Reasoning about constraints, constraint programming

- Reasoning about knowledge, beliefs, and other mental attitudes

- Uncertainty, vagueness, many-valued and fuzzy logics

The KR2021 program will also feature workshops and tutorials, solicited by means of an open call, as well as a doctoral consortium.

** TRACKS AND SPECIAL SESSIONS **

In addition to the main conference track, KR2021 will host the following tracks and sessions:

* Applications and Systems Track

* Recently Published Research Track

* Special Session on KR and Machine Learning

* Special Session on KR and Robotics

** IMPORTANT DATES **

Submission of title and abstract:     March 24, 2021

Paper submission deadline:          March 31, 2021

Author response period:         May 24-26, 2021

Notification:                 June 15, 2021

Camera-ready papers:             July 14, 2021

Conference dates:             November 6-12, 2021

The Recently Published Research track, workshops, tutorials, and the doctoral consortium have different submission and notification dates, which are listed on the conference website.

**AUTHOR GUIDELINES AND SUBMISSION INFORMATION**

All submissions must be written in English and formatted using the style files provided on the KR'21 website. Papers must be submitted in PDF format, through the EasyChair conference system:

https://easychair.org/conferences/?conf=kr2021

For the main conference track and additional tracks/sessions (except for the Recently Published Research track), we invite

- Full papers of up to 9 pages, including abstract, figures, and appendices   (if any), but excluding references and acknowledgements.

- Short papers of up to 4 pages, excluding references and acknowledgements.

Both full and short papers must describe original, previously unpublished research, and must not simultaneously be submitted for publication elsewhere. These restrictions do not apply to previously accepted workshop papers with a limited audience and/or without archival proceedings, and to papers uploaded at public repositories (e.g., arXiv).

Accepted full papers and short papers will be published in the KR2021 proceedings.

Authors may optionally submit a separate PDF containing additional information that substantiates the claims made in their paper, such as proof details, additional experimental results, further details on experimental design, etc. If authors wish to make such material available to reviewers, they should do so by submitting a file through EasyChair, rather than by including links or references in their paper. Please note that the main paper must be self contained, as the supplementary material will not be published. Moreover, reviewers will have the option but not the obligation to consult the supplementary material.

The preceding submission guidelines apply to the main track, as well as to the Applications and Systems track, the KR & Machine Learning special session, and the KR & Robotics special session. By contrast, different submission guidelines apply to the Recently Published Research track, workshops, tutorials, and the doctoral consortium, please consult the KR21 website for further information.

** REMOTE PARTICIPATION DUE TO COVID-19 PANDEMIC **

We understand that the global public health situation may make it difficult or impossible for some, if not all, participants to travel to Hanoi. For this reason, we commit to allowing authors of accepted papers to present virtually and will work hard to enable the best possible experience for all conference participants.
