1983 Edition 2 The MRS Casebook edited by Michael R. Genesereth Department of Computer Science School of Humanities and Sciences Stanford University

MRS is a knowledge representation system intended for use by Al researchers in building expert systems. It offers a dkerse repertory of commands for asserting and retrieving information. The initial system includes a vocabulary of concepts and facts about logic, sets, mappings, arithmetic, and procedures. What differentiates MRS from many other knowledge representation systems is its ability to reason about and control its own activity. In MRS the system is treated as a domain in its own right.
