KNOWLEDGE REPRESENTATION FOR EXPERT SYSTEMS. MAREK PETRIK. Abstract. The purpose of this article is to summarize the state-of-the-art of the. Logic as knowledge representation in expert system. The formal logic systems use~ to represent. declarative.. knowledge in AI are propositional calculus. Expert Systems. • Knowledge Representation. • Production Systems. • CLIPS - the C Language Integrated Production System. • Reasoning under Uncertainty. Introduction. Knowledge representation it is an infrastructure of an expert system[ 5], which introduced many method for this. On the other part, we live in advance. Knowledge representation and reasoning / Ronald J. Brachman, Hector J. Levesque. p. cm. Includes this paradox of “expert systems.” These systems are. From Feigenbaum: An Expert system is “an intelligent computer program that uses knowledge and inference procedures to solve problems that are difficult. Knowledge Engineering. Definition 1 (Knowledge Engineering). The process of designing knowledge- based systems (e.g. expert systems, data-driven models). emerging as one of the most important methods for constructing expert systems which reason under uncertainty. Chapter 7 counters the claim that inference rules are unsuitable as a knowledge representation when uncertainty is involved. A rule-based repre­ sentation is derived, employing a model first introduced in Chapter 3: the. Reid G. Smith is the program leader for Expert Geology Systems at Schlumberger-Doll Research, Ridgefield, Connecticut, where he has been since His current research is on expert systems which explain failures and develop justifications for the information in their knowledge bases. to speak of knowledge systems or knowledge-based systems than of expert systems. Neither should it be excluded that knowledge in an expert system is based on a scientific theory or on functional or causal models belonging to a particular domain. Advances in research in the field of expert systems and increasing knowledge derived from v. modern expert systems and shells such as Gensym’s G2 and also some light-weight prolog based expert systems, usually based on deep knowledge of the domain. In the forth section, we compare various knowledge representation languages. • Expert systems, language understanding, • Many of the AI problems today heavily rely on statistical representation and reasoning – Speech understanding, vision, machine learning, natural language processing • For example, the recent Watson system relies on statistical methods but also uses some symbolic representation and reasoning.
