Expert System

EXPERT SYSTEMS One of the largest argona of applications of artificial wisdom is in adept sytems, or knowledge leveld systems as they are often known. This example of system seeks to exploit the specialised skills or information held by of a group of people on specific areas. It dissolve be panorama of as a computerised consulting service. It can to a fault be called an information guidance sytem. much(prenominal) systems are expendd for prospecting health check diagnosis or as educational aids. They are in addition 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 start seen but it was soon realised that more(prenominal) significant progress could be made if the field of use up was restricted. STRUCTURE The inwrought structure of an expert system can be considered to be of three parts: the knowledge base ; the database; the observe interpreter. This is analagous to the merchandise system where we have the tag of productions; the redact of facts held as shamus memory and a rule interpreter. ////////////////http://www.cs.cf.ac.uk/Dave/AI1/ailect18mycin1.gif The knowledge base holds the traffic circle 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 few hundred to a few thousand rules. The database gives the stage prospect of the problem domain and is generally considered to b e a set of useful facts. These are the facts! that satisfy the setting part of the correct action rules as the IF THEN rules can be thinking of. The rule interpreter is often known as an induction engine and controls the knowledge base using the set of facts to drive at even more facts. Communication with the sytem is ideally provided by a natural language interface. This enables a user to interact indelendently of the expert with the intelligent system.
