N Reasons Why Production-Rules are Insufficient Models for Expert System Knowledge Representation Schemes

Abstract : The majority of expert system shells and fully developed expert system packages are founded upon simple observation and hypothesis production- rules. This paper investigates the use of such knowledge representation schemes by analysis of a simple, incomplete plant classification expert system. Furthermore, a new hierarchical knowledge representation scheme known as the n-Cube, which is suitable for classification applications, is discussed with reference to the disadvantages of rule-based systems.
