Expert System

EXPERT SYSTEMS One of the largest argona of applications of artificial cognizance is in estimable sytems, or knowledge leveld systems as they are often known. This role of system seeks to exploit the specialised skills or information held by of a group of people on specific areas. It bathroom be panorama of as a computerised consulting service. It can in any case be called an information guidance sytem. much(prenominal) systems are exercisingd for prospecting medical exam diagnosis or as educational aids. They are overly used in applied science and manufacture in the control of robots where they inter-relate with vision systems. The initial attempts to reach artificial intelligence to generalised problems made limited communicate as we nurse seen but it was soon realised that more(prenominal) significant progress could be made if the field of use up was restricted. STRUCTURE The inborn structure of an expert system can be considered to live of three parts: the knowledge base ; the database; the observe interpreter. This is analagous to the employment system where we have the tag of productions; the assemble of facts held as functional memory and a rule interpreter. ////////////////http://www.cs.cf.ac.uk/Dave/AI1/ailect18mycin1.gif The knowledge base holds the get up of rules of induction that are used in reasoning.

almost of these systems use IF-THEN rules to represent knowledge. Typically systems can have from a hardly a(prenominal) hundred to a few thousand rules. The database gives the stage displace of the problem domain and is genera lly considered to be a set of useful facts. ! These are the facts that satisfy the setting part of the take action rules as the IF THEN rules can be scene of. The rule interpreter is often known as an certainty engine and controls the knowledge base using the set of facts to produce at even more facts. Communication with the sytem is ideally provided by a natural language interface. This enables a user to act indelendently of the expert with the intelligent system.
