Introduction to Expert Systems

Consultants justify their recommendations by explaining their reasoning [12]

When a car won't start my initial suspicion is that the battery is dead, the starter has failed or some other electrical problem exists. Your input that the starter operates makes it more likely that no fuel is getting to the engine. Although you are not sure that the gas tank is empty, the fact that you don't smell gas when the engine turns over supports my conclusion that you are out of gas.

The application of expertise is not a guessing game. A real expert should be able to explain how evidence was used to evaluate rules-of-thumb to develop recommendations.

Given the nature of the consulting process just described, does it make sense to try to deliver advice without the physical presence of an expert?
