How do you evaluate an expert system?

The proposed model’s evaluation criteria are: usability, utility, quality, interface, structure, productivity and return. Information systems, especially expert systems, are today a real necessity for any organisation intending to be competitive.

What are the types of expert system?

There are five basic types of expert systems. These include a rule-based expert system, frame-based expert system, fuzzy expert system, neural expert system, and neuro-fuzzy expert system. A rule-based expert system is a straightforward one where knowledge is represented as a set of rules.

What are three critical components of an expert system?

An expert system is typically composed of at least three primary components. These are the inference engine, the knowledge base, and the User interface. We will introduce these components below.

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.

Why do we need to evaluate from experts?

It is important to periodically assess and adapt your activities to ensure they are as effective as they can be. Evaluation can help you identify areas for improvement and ultimately help you realize your goals more efficiently.
