BANTER - A BAYESIAN NETWORK TUTORING SHELL

We present an educational tool for bringing the information contained in a Bayesian network to the end user in an easily intelligible form. The BANTER Shell is designed to tutor users in evaluation of hypothese s and selection of optimal diagnostic procedures. BANTER can be used w ith any Bayesian network containing nodes that can be classified into hypotheses, observations, and diagnostic procedures. The system enable s one to present various types of queries to the network, to test one' s ablity to select optimal diagnostic procedures, and to request expla nations. We describe the system's capabilities by illustrating how it functions with two structurally different network models of real-world medical problems. (C) 1997 Elsevier Science B.V.
