20 - 23 July 2026, 23rd Int. Conference on Principles of Knowledge Representation and Reasoning (KR 2026), Lisbon, Portugal

Date: 20 - 23 July 2026
Location: Lisbon, Portugal
Deadline: Friday 13 February 2026

Knowledge Representation and Reasoning (KR) is a well-established and vibrant field of research within Artificial Intelligence. KR builds on the fundamental thesis that knowledge can often be represented in an explicit declarative form, suitable for processing by dedicated symbolic reasoning engines. This enables the exploitation of knowledge that would otherwise be implicit through semantically grounded inference mechanisms. KR has contributed to the theory and practice of various areas of AI, including agents, automated planning, robotics and natural language processing, and to fields beyond AI, including data management, semantic web, verification, software engineering, computational biology, and cybersecurity.

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

KR2026 will be part of the Federated Logic Conference (FLoC 2026).

We solicit papers presenting novel results on the principles of KR, which clearly contribute to the formal foundations of the field or show the applicability of KR techniques to implemented or implementable systems. We welcome papers from other areas that demonstrate clear use of, or contributions to, the principles or practice of KR. We also encourage "reports from the field" of applications, experiments, developments, and tests.

20 - 23 July 2026, 23rd Int. Conference on Principles of Knowledge Representation and Reasoning (KR 2026), Lisbon, Portugal

Date: 20 - 23 July 2026
Location: Lisbon, Portugal
Deadline: Friday 13 February 2026

Knowledge Representation and Reasoning (KR) is a well-established and vibrant field of research within Artificial Intelligence. KR builds on the fundamental thesis that knowledge can often be represented in an explicit declarative form, suitable for processing by dedicated symbolic reasoning engines. This enables the exploitation of knowledge that would otherwise be implicit through semantically grounded inference mechanisms. KR has contributed to the theory and practice of various areas of AI, including agents, automated planning, robotics and natural language processing, and to fields beyond AI, including data management, semantic web, verification, software engineering, computational biology, and cybersecurity.

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

KR2026 will be part of the Federated Logic Conference (FLoC 2026).

We solicit papers presenting novel results on the principles of KR, which clearly contribute to the formal foundations of the field or show the applicability of KR techniques to implemented or implementable systems. We welcome papers from other areas that demonstrate clear use of, or contributions to, the principles or practice of KR. We also encourage "reports from the field" of applications, experiments, developments, and tests.
