The benchmark expert systems have proven the feasibility of using knowledge-based systems for solving problems traditionally requiring human experts. Predominantly forward chaining (data-driven), with some back­ward chaining. It provides developers with knowledge acquisition, inference engine, user interface, and explanation facility. When the general category of infection has been established, MYCIN examines each candidate diagnosis in a depth-first manner. It is also capable of recommending drugs based on a person’s weight. Expert System is an interactive and reliable computer-based decision-making system which uses both facts and heuristics to solve complex decision-making problems. In this article we will discuss about the examples of expert system. Artificial Intelligence System Examples Expert System Team An artificial intelligence system that can do difficult tasks such as reading, understanding and learning, has for decades been one of artificial intelligence’s biggest challenges. It contains the basic components of expert systems. Vidwan, a shell developed at the National Centre for Software Technology, Mumbai in 1993. Expert System Pros and Cons.

The knowledge acquisition system KAS has been developed for easy editing and expansion of the inference network structure in which the knowledge base is stored. It is determined at the time of designing the system. PROSPECTOR is an expert system which was designed for decision making problems in mineral exploration. An expert system’s clientele continue to demand refinement of existing capabilities and extension of the boundaries of the domain of its expertise. The deflected chunks are collected, forming a spectrogram. A Data Mart is focused on a single functional area of an organization and... Data can be organized and simplified by using various techniques in Tableau. During the early 1970s, human experts—known as technical editors—ensured that each computer system on order had all the necessary components and no extras … Unable to make a creative response in an extraordinary situation, Errors in the knowledge base can lead to wrong decision, The maintenance cost of an expert system is too expensive, Each problem is different therefore the solution from a human expert can also be different and more creative, Useful for repair and maintenance projects, The configuration of manufactured objects, Financial decision making Knowledge publishing, Supervise the operation of the plant and controller, An Expert System is an interactive and reliable computer-based decision-making system which uses both facts and heuristics to solve complex decision-making problem, Key components of an Expert System are 1) User Interface, 2) Inference Engine, 3) Knowledge Base, Key participants in Artificial Intelligence Expert Systems Development are 1) Domain Expert 2) Knowledge Engineer 3) End User, Improved decision quality, reduce cost, consistency, reliability, speed are key benefits of an Expert System. The savings produced by XCON has convinced DEC management that artificial intelligence, particularly its application to expert systems, has a bright future.
