Expert Systems (COSC 208) What is an Expert System? Expert system is an artificial intelligence program that has expert-level knowledge about a particular domain and knows how to use its knowledge to respond properly. In this context‚ a domain refers to the area within which the task is being performed. Ideally the expert systems should substitute a human expert. Edward Feigenbaum of Stanford University has defined expert system as “an intelligent computer program that uses knowledge and inference

Q1. What is the dual-court system? Why do we have a dual court system? A. The dual-court system is the result of a general a agreement among the nation’s founders about the need for individual states to retain significant legislative authority and judicial autonomy separate from federal control. The reason why we have a dual-court system is‚ back then; new states joining the union were assured of limited federal intervention into local affairs. The state legislatures were free

Artificial Intelligence Question for reviews 1. What is knowledge? Why experts usually have detailed knowledge of a limited area of a specific domain. What do we mean by heuristic? Knowledge is something theoretical or practical understanding the subject‚ which can include facts‚ information‚ descriptions or skills. Knowledge is the sum of what is currently known. 2. What is a production rule? Give an example and define two basic parts of the production rule. Production rule is a mechanism

basic components of a CDSS include a dynamic (medical) knowledge base and an inferencing mechanism (usually a set of rules derived from the experts and evidence-based medicine) and implemented through medical logic modules based on a language such as Arden syntax. It could be based on Expert systems or artificial neural networks or both (connectionist expert systems). Bayesian Network [edit] The Bayesian network is a knowledge-based graphical representation that shows a set of variables and their probabilistic

through the use of expert system technology”. The problem is how to acquire the specific knowledge for a selected problem efficiently and effectively from human experts and to encode it in the suitable computer format. Acquiring knowledge from human experts in the process of Expert Systems development is one of the most common problems cited till yet. This questionnaire was sent to 87 domain experts within all public and private universities of Pakistan. Among them 25 domain experts sent their valuable
