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..
Thereof, what are examples of expert systems?
Examples of Expert Systems
- MYCIN: It was based on backward chaining and could identify various bacteria that could cause acute infections.
- DENDRAL: Expert system used for chemical analysis to predict molecular structure.
- PXDES: Expert system used to predict the degree and type of lung cancer.
Also Know, what is expert support system? Meaning of Expert System: Decision support systems aid in problem solving by allowing for manipulation of data and models. An expert system is a computer based information system in which knowledge is represented in data, in which the processing of the knowledge is directed primarily by computer programs.
Thereof, 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. We discussed the expert systems based on their knowledge representation, inference engine, working of the system and user interface.
How do expert systems work?
The expert system works by providing solutions to problems through the reasoning that is at the level of human. but they are much faster to provide solutions to problems, and they use symbols to explain the solutions. Most expert systems are production systems which have at their heart the Rete algorithm .
