Expert System
What is Expert System ?
· An expert system is a computer program that simulates the thought process of a human expert to solve complex decision problems in a specific domain.
• An expert system, is an interactive computer-based decision tool that uses both facts and heuristics to solve difficult decision making problems, based on knowledge acquired from an expert.
• An expert system is a model and associated procedure that exhibits, within a specific domain, a degree of expertise in problem solving
that is comparable to that of a human expert.
• An expert system compared with traditional computer :
Inference engine + Knowledge = Expert system
( Algorithm + Data structures = Program in traditional computer )
· The Need for Expert Systems
· Benefits of Expert Systems
Expert systems offer an environment where the good capabilities of humans and the power of computers can be incorporated to overcome many of the limitations discussed in the previous section. Expert systems:
2-Applications of Expert System
3-Expert System Characteristics
Expert system operates as an interactive system that responds to
questions, asks for clarifications, makes recommendations and generally
aids the decision-making process.
Expert systems have many Characteristics:
? Operates as an interactive system.
? Tools have ability to sift (filter) knowledge
? Make logical inferences based on knowledge stored
?Ability to Explain Reasoning
? Domain-Specific
? Capability to assign Confidence Values
? Cost-Effective alternative to Human Expert
