Abstract

In this paper a powerful tool called sensitivity analysis in the context of knowledge engineering is discussed. Subtleties related to the popular certainty factor calculus employed by most shells are highlighted. With reference to practical examples, we also show how sensitivity analyses can help validate a knowledge base. Keywords: Sensitivity analysis, Expert Systems, Knowledge Base, Knowledgebased Systems 1 Introduction The ultimate product of the process of knowledge engineering is to produce knowledge-based systems - systems exhibiting intelligent behavior by modelling the empirical associations and heuristic relationships that experts have acquired over time. During the process, knowledge of the expert(s) is acquired and some model is established for the building
