1. Expert System Participants
Domain expert
Knowledge engineer
Knowledge user

2. The domain expert
The individual or group that has the expertise or knowledge one is trying to capture in the expert system.
Recognizes the real problem
develops a general framework for problem solving
formulates theories about the situation
develops and uses general rules to solve a problem
knows when to break the rules or general principles
solves problems quickly and efficiently
learns from past experiences
knows what is important in solving a problem and what is not
explains the situation and solutions of problems to others

3. The knowledge engineer
The individual who has training and/or experience in the design, development, implementation, and maintenance of an expert system, including training and/or experience with expert system shells.
As expert systems shells and development tools become easier to use, the role of the knowledge engineer shifts from system developer to consultant

4. The Knowledge User
The individual or group who uses and benefits from the expert system. Knowledge users do not need any previous training in computers or expert systems.

5. Expert System Development
Theoretically, expert systems can be developed from any programming language.
Early days: Pascal, FORTRAN, COBOL
NEXT: LISP for AI, then Prolog for AI
Now: Financial Advisor, 1st Class Fusion, Knowledepro, Leonardo, Personal Consultant (PC) Easy are a few used today.

6. Other Business Uses of Expert Systems
Kaiser Permanente- uses and expert system and voice response to automate its help desk function
Nynex(newyork/new england tel exch)--uses expert systems to help its workers locate and solve customer-related phone problems
MYCIN(Stanford) uses system to analyze blood infections
CARGEX-uses system to help determine the best shipping routes
CoverStory-uses system to extract marketing info from database and automatically write marketing reports.

7. Integrating Expert Systems
An expert system can be integrated with other information systems in an organization through a common database.
Expert systems support managerial decision making and organizational goals.

8. Think About it
Think of five ideas for expert systems that would be useful on campus
Try to develop rules you might use to make decisions (ie: to choose classes for a quarter)
this exercise will show the difficulty of using multiple experts (other students in your group) to build a knowledge base and the difficulty of defining rules for a knowledge base.
