An artificial intelligence inference engine that operates on the principles of deductive reasoning, processing a set of declarations about a specific domain expressed in a frame language. The primary function is to assess the logical consistency of these declarations and, if inconsistencies are found, attempt to resolve them. When the declarations are consistent, the classifier can infer additional information.

A deductive classifier could be used to analyze a set of medical diagnoses and prescriptions provided by a doctor. The classifier would process the declarations about the symptoms, diagnoses, and treatments, checking for logical consistency and attempting to resolve any inconsistencies. Based on the consistent declarations, the classifier could infer additional information such as potential side effects or drug interactions.
