Provide expertise needed for training and development to share the wisdom of human experts with a large number of people
Participants in Expert Systems Development and Use
Domain expert
The individual or group whose expertise and knowledge is captured for use in an expert system
Knowledge user
The individual or group who uses and benefits from the expert system
Knowledge engineer
