Abstract:

We present CSRLConceptual Structures Representation Language as a language to facilitate the development of expert diagnosis systems based on a paradigm of cooperating diagnostic specialists. MDX, the medical diagnosis system that has been developed in our laboratory over the past few years is based on this paradigm. In our approach, diagnostic reasoning is one of several generic tasks, each of which calls for a particular organizational and problem solving structure. A diagnostic structure is composed of a collection of specialists, each of which corresponds to a node or concept in a diagnostic hierarchy, e.g., a classification of diseases. A top-down strategy called establish-refine is used in which either a specialist establishes and then refines itself, or the specialist rejects itself, pruning the hierarchy that it heads. CSRL is a language for representing the concepts of a diagnostic hierarchy and for implementing the establish-refine process. The body of a concept specifies how it will respond to different messages from its super concept. The knowledge to establish or reject a concept is factored into knowledge groups, which corresponds to specific decisions in the diagnosis. Author
