Abstract
A knowledge acquisition methodology, Ripple Down Rules, has been developed which only allows knowledge to be used in the context in which it is acquired and ensures that only valid rules can be added to a knowledge base. This method has now been used to build a large (2000 rule) medical expert system. This system is in routine use in a Chemical Pathology laboratory providing clinical interpretations for laboratory reports. It has been developed entirely by experts with no knowledge acquisition or programming support or skills. This task was a minor extension to their normal duties. This paper describes the resultant knowledge base and concludes that such knowledge acquisition is very simple. It claims that allowing knowledge to be easily refined is a powerful technique which greatly simplifies dealing with complex domains. INTRODUCTION TO RIPPLE DOWN RULES Ripple down rules (RDR) is a knowledge acquisition methodology and a way of structuring knowledge bases which grew o...
