KR 2021
18th International Conference on Principles of
Knowledge Representation and Reasoning

Welcome to KR 2021

Welcome to the website of the 18th International Conference on Principles of Knowledge Representation and Reasoning to be held online on November 3-12, 2021 (with workshops and tutorials scheduled during November 3-7, and the main conference from November 8-12).

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.

  KR 2021 will be an online event

We had very much hoped to meet in Hanoi, Vietnam, but due to the ongoing pandemic, it has been decided to hold KR 2021 as a fully online event. While we are sad to not be able to meet in Hanoi in person, we are working hard to enable the best possible experience for conference participants.

  We are holding a Live KR 2021 gathering in Rome!

One of the activities that we have organized is a live KR 2021 gathering in Rome at Sapienza. This gathering will last from Nov 8 to Nov 12, 2021 (covering the main conference only). It will provide rooms for attending the streamed talks together, and facility to present live talks and simultaneously stream them online. The registration to the gathering is free, though limited to 50 people only (locals excluded). Registrations will be granted by using a first-come-first-served policy. The Green pass or similar will be required to attend. More info on this page.
