32. Intelligent System A System can be constructed as a intelligence system if it has four major techniques of knowledge representation. 1.Logic The logic is a formal procedure because of which implications are created from the set of known facts. 2.Production Systems The production systems studies the new facts and the known facts and finds the desired conclusion. 3.Semantic networks It is a network of symbols that describe relationship between elements of knowledge 4.Frames These are the data structures which consists of expectations for a given situation.
