expert system - Free On-line Dictionary of Computing (26 May 2007) :

  expert system
  
     <artificial intelligence> A computer program that contains a
     knowledge base and a set of algorithms or rules that infer
     new facts from knowledge and from incoming data.
  
     An expert system is an artificial intelligence application
     that uses a knowledge base of human expertise to aid in
     solving problems.  The degree of problem solving is based on
     the quality of the data and rules obtained from the human
     expert.  Expert systems are designed to perform at a human
     expert level.  In practice, they will perform both well below
     and well above that of an individual expert.
  
     The expert system derives its answers by running the knowledge
     base through an inference engine, a software program that
     interacts with the user and processes the results from the
     rules and data in the knowledge base.
  
     Expert systems are used in applications such as medical
     diagnosis, equipment repair, investment analysis, financial,
     estate and insurance planning, route scheduling for delivery
     vehicles, contract bidding, counseling for self-service
     customers, production control and training.
