What is an Expert System?

Any software which behaves, advice or help you like an expert is called an Expert System.1 .

An Expert System is a computer system that emulates the decision-making ability of a Human Expert.2

Expert System consists of the rules and knowledge from more than one Expert.3

7

What is an Expert System? (cont.)

An Expert System contains accumulated experience and set of rules for applying the knowledge to each particular situation that is given by user as a query or requirements of a particular problem.4

Typically, Expert Systems are designed to solve complex problems by reasoning about knowledge, represented mainly as if-then rules rather than through procedural code.5 .

How does an Expert System work? (cont.)

User Interface: This is screen for user to receive the query or requirements

of problem. 6

Inference (Rules) Engine: This is also known as brain of expert system which contains

the rules to solve a particular problem on the behalf of knowledge from Knowledge Base.7

Knowledge Base: Container of knowledge that is obtained from different

experts of a particular field while development.8

Limitations

In Expert System there is no common sense used in making

decisions.15

It requires cost to buy and set up the system. 16

They have lack of creative responses that human experts are

capable of. 17

They are not able to learn from the mistakes. 18

Expert System will need continuous updating, which can take

it temporarily out of use. 19

Conclusion

Very interesting field of Artificial Intelligence. As an Expert has knowledge that help to advice,

same like that Expert Systems has knowledge base that helps inference engine to advice.

Expert System may result much better than an human expert because it contains several expertise.

When implemented correctly, expert systems may remove human error.

Expert system can be also used as a tool for organizing researchers knowledge.
