Knowledge based standards processing

Abstract

This paper presents the representational model of a standard, background research in standards processing, and a current research project which uses a knowledge-based system approach to standards processing. The representational model of a standard, based on decision tables, was originally developed in 1966 and has been continually modified and improved since that time. Concurrent with the development of this model was the development of its uses in computer-aided standards processing, such as automated conformance checking and design. As an extension of this standards processing research, a knowledge-based standards processor is being built that will act as an interface between CAD programs and design standards. The knowledge-based standards processor uses a blackboard architecture similar to that of Hearsay-II, a speech understanding program. The processor's knowledge is divided up into about ten knowledge sources, most of which are standard-independent. The knowledge sources are responsible for the development of a design script that can be used to perform the CAD program's member design tasks, while satisfying the governing design standard.
