title: Validation of expert systems: examples and considerations.
abstract: The problem of a medical expert system validation is generally complex. It requires a rigorous methodology of validation and must show proof of its practical competency in order to be used currently. Validation concerns the quality of conclusions provided by the system, the quality of the deductive process leading to these conclusions as well as the validity of its utilization. In this paper, some reflections, questions, and requirements are exposed that must be addressed to proceed to the validation of a knowledge base system in the field of medicine, especially the psychiatric field.
