Abstract
An expert system for process control, which permits the inference rules to be revised at any time without requiring the specialized skills of a 'knowledge engineer'. The inference rules are intitially defined by a domain expert who fills in blank fields in a set of highly constrained substantially natural-language templates. The rule set thus specified is automatically translated to define an operational expert system. Updating can be performed by a domain expert at any time: the set of templates with the data fields as originally entered is redisplayed, so that the domain expert can edit the accessible fields and then command the modified rule set to be automatically translated, to define a modified operational expert system.
