What is an expert system in business?

A Business Expert System (BES) is a knowledge based information system, which is based on artificial intelligence. A Knowledge Based information system adds a knowledge base that uses its knowledge about a specific, complex application area to act as an expert.

Keeping this in view, how are expert systems used in business?

Expert systems are used widely in commercial and industrial settings, including medicine, finance, manufacturing, and sales. Through a procedure known as knowledge transfer, expertise (or those skills and knowledge that sustain a much better than average performance) passes from human expert to knowledge engineer.

It could also recommend drugs based on the patient's weight. DENDRAL: Expert system used for chemical analysis to predict molecular structure.

Thereof, what do you mean by expert system?

In artificial intelligence, an expert system is a computer system that emulates the decision-making ability of a human expert. Expert systems are designed to solve complex problems by reasoning through bodies of knowledge, represented mainly as if–then rules rather than through conventional procedural code.

What is the main purpose of expert systems?

The purpose of an expert system is to provide reasoned advice at a comparable level to that provided by a human expert. This capability has two main aims :to enhance the abilities of leading experts in certain fields and to make a high level of expertise available to less highly qualified practitioners.

What are the types of expert system?

There are mainly five types of expert systems. They are rule based expert system, frame based expert system, fuzzy expert system, neural expert system and neuro-fuzzy expert system.

Combine various human expert intelligences.

What is the structure of expert system?

The internal structure of an expert system can be considered to consist of three parts: the knowledge base ; the database; the rule interpreter. the set of productions; the set of facts held as working memory and a rule interpreter. The knowledge base holds the set of rules of inference that are used in reasoning.

What are the characteristics of expert system?

Characteristics of an expert system: One expert system may contain knowledge from more than one human experts thus making the solutions more efficient. It decreases the cost of consulting an expert for various domains such as medical diagnosis. They use a knowledge base and inference engine.
