The overall purpose of an inference engine is to seek information and relationships from the knowledge base and to provide answers, predictions, and suggestions similar to the way a human expert would. The explanation facility allows a user or decision maker to understand how the expert system arrived at certain conclusions or results. The expert system, using the explanation facility, can indicate all the facts and rules that were used in reaching the conclusion.
