The International Conference on Principles of Knowledge Representation and Reasoning

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.

In addition to the Main track, KR 2026 will include two special thematic tracks:

  • KR meets Machine Learning and Explanation
  • KR in the Wild.

KR 2026 will also include a Recently Published Research track, a Video track, tutorials, workshops, and a Doctoral Consortium.

Calls for papers dedicated to these special tracks and other events will be distributed in due course and made available on the website.
