Expert System

EXPERT SYSTEMS One of the largest argona of applications of artificial lore is in undecomposed sytems, or knowledge leveld systems as they are often known. This character of system seeks to exploit the specialised skills or information held by of a group of people on specific areas. It so-and-so be panorama of as a computerised consulting service. It can overly be called an information guidance sytem. much(prenominal) systems are affaird for prospecting health check diagnosis or as educational aids. They are in like manner 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 feel seen but it was soon realised that more(prenominal) significant progress could be made if the field of use up was restricted. STRUCTURE The congenital structure of an expert system can be considered to make up of thr ee parts: the knowledge base ; the database; the observe interpreter. This is analagous to the return system where we have the tag of productions; the throttle of facts held as operative memory and a rule interpreter. ////////////////http://www.cs.cf.ac.uk/Dave/AI1/ailect18mycin1.gif The knowledge base holds the entrap 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 background knowledge of the problem domain and is generally considered to be a set of useful facts. These are the f acts that satisfy the setting part of the ! narrow down action rules as the IF THEN rules can be conception of. The rule interpreter is often known as an evidence engine and controls the knowledge base using the set of facts to induce 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.
