CALL FOR PARTICIPATION

18th International Conference on Principles of Knowledge Representation and Reasoning (KR 2021) November 3-12, 2021 - Virtual https://kr2021.kbsg.rwth-aachen.de/

*** Registration is free but mandatory (deadline: October 15, 2021) ***

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.

CONFERENCE FORMAT AND REGISTRATION

KR 2021 will be organized as a virtual conference and welcomes all researchers interested in KR to participate!

We are happy to announce that participation is *free*. The deadline for registering is October 15, 2021. Information about how to register for the main conference and associated events can be found at:
