• The inference engine solves a problem by using domain knowledge. For
example, using the domain knowledge for medical diagnosis, a problem is solved
about what disease is expected for a given symptom.
• The inference explanation module explains the problem solving process,
that is, why a particular disease is expected from the given symptom.
• The knowledge-base editor provides the facilities for inputting information
and editing or maintaining the knowledge base. For example, a set of a symptom
and its disease is input by using the knowledge-base editor.
• The human-machine interface module interprets users' requests to the system,
given in written language, images, spoken language, or gestures. The module inter-
prets the requests and translates them into machine-understandable form.
