DONALD A. WATERMAN, Frederick A. Hayes-Roth · RAND Corporation eBooks · 1978
Pattern-directed inference systems are programs that look for interesting or important situations occurring as patterns in the input or memory data to direct their activity.These patterns select pieces of program code to be executed.In this paper a brief overview of pattern-directed inference systems is presented, including an historical perspective, a review of basic concepts, and a survey of current work in this area.Examples of the best known type of pattern-directed inference system, the production system, are presented and discussed in detail.
