More on Goal-Directed Diagnosis

In many diagnosis-and-repair domains, diagnostic reasoning cannot be abstracted from repair actions, nor from actions necessary to obtain diagnostic information. We call these exploratory-corrective domains. In TraumAID 2.0, a consultation system for multiple trauma management, we have developed and implemented a framework for reasoning in such domains which integrates diagnostic reasoning with planning and action. In this paper, we present Goal-Directed Diagnosis (GDD), the diagnostic reasoning component of this framework. Taking the view that a diagnosis is only worthwhile to the extent that it can affect subsequent decisions, GDD focuses on the formation of appropriate goals for its complementary planner.
