D-SCRIPT: A Computational Theory of Descriptions

Unknown author (1973-02-01)

This paper descries D-SCRIPT, a language for representing knowledge in artificial intelligence programs. D-SCRIPT contains a powerful formalism for descriptions, which permits the representation of statements that are problematical for other systems. Particular attention is paid to problems of opaque contexts, time contexts, knowledge about knowledge. The design of a theorem prover for this language is also considered.
