What is expert system in decision-making?

In artificial intelligence, an expert system is a computer system emulating 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.

Which type of approach does expert systems require?

An expert system (ES) is a knowledge-based system that employs knowledge about its application domain and uses an inferencing (reason) procedure to solve problems that would otherwise require human competence or expertise.

How do expert systems help in decision-making?

Abstract: Expert system is a term that describes a computer program that simulates the judgment and behaviour of a human or an organization that has expert knowledge and experience in a particular field. Our aim is to design an expert system which will help a person to take decision based upon his previous decisions.

Is an expert system a decision support system?

“Decision Support System” (DSS) and “Expert System” (ES) are two more buzzwords in the information technology community. Using the idea that DSS and ES are approaches rather than just systems, a conceptual framework is presented for comparing the two in the context of management problems.

What is an expert system what are the characteristics of an expert system?

An expert system operates as an interactive system that responds to questions, asks for clarification, makes recommendations and generally aids the decision making process. Expert system provides expert advice and guidance in a wide variety of activities from computer diagnosis to delicate medical surgery.

How do expert systems differ from decision support systems?

DSS	Expert System
It uses goals and system data to establish alternatives and outcomes, so a good decision can be made.	The expert system can eventually replace the human decision maker.

What is expert support system?

Expert support systems (ESSs) promise valuable support to decision-makers in business settings where a number of complex and interacting decisions must be accommodated. These factors are identified by considering factors that are relevant to MIS development and how they relate to the new technology of expert systems.
