D-SCRIPT: A Computational Theory of Descriptions
Moore, Robert C.

Formato:
Enlaces:	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…
