Formal Logic For Expert Systems
The machinery of an expert system essentially consists of a representation language and an inference method (Luger and Stubblefield 1989). The representation language commonly used is that of production rules, simple if-then constructs which specify the conditions under which a conclusion can be said to follow. The inference method links sequences of these rules together by means of backward or forward chaining to extrapolate conclusions from the knowledge base.
