# Meta-Knowledge and Cognition

Avron Barr

*Proceedings of the Sixth International Joint Conference on Artificial Intelligence*.

## Abstract

In AI knowledge representation schemes, structures that describe other structures are said to represent "meta-knowledge," or knowledge about other knowledge. After describing some studies of human behavior that demonstrate people's ability to reason about what they know and about how they reason, we review the use of explicit meta-knowledge In several rescent AI systems. The concept of meta-level knowledge captures Intrinsic, commonplace properties of human cognition that are central to an underatandlng of knowledge and lnteiHgence.
