This expert system is designed to be used by students to easily obtain references on mechanical engineering topics. The expert system shell, 'INSIGHT,' has been used to develop the knowledge base. The input is in the form of a selection from a list of choices or a true/false reply. Given the input, the program decides whether a certain set of rules can be applied to reach a conclusion. In the event that a conclusion can be reached, the screen shows which conclusion is appropriate. In addition a display is shown giving the chapter and page numbers of reference materials. There are over two hundred and fifty rules in the knowledge base, and a similar number of display screens that provide the reference information. This constitutes over five thousand facts in the knowledge base, which is pushing the limit of the expert system shell. Three important guidelines are followed to keep this large knowledge base well structured: the conclusions are kept simple, procedural content is removed from the rules, and the use of ELSE is eliminated.
