Introduction
• The knowledge engineer is the developer whose job is to extract the expertise from the
domain expert.
• The knowledge user is the person who benefits from the use of the developed system.
• Expert systems can be implemented in several ways.
• Previously, traditional high-level languages, including Pascal, FORTRAN, and COBOL,
were used.
• LISP and PROLOG are two languages specifically developed for creating expert systems
from scratch.
• A faster and less-expensive way to acquire an expert system is to purchase an expert
system shell or existing package.
• The shell program is a collection of software packages and tools used to design, develop,
implement, and maintain expert systems.
• The benefits of using an expert system go beyond the typical reasons for using a
computerized processing solution.

draw conclusions, provide portable knowledge, and can deal with uncertainty.
• Expert systems can be used to solve problems in many fields or disciplines and can assist
in all stages of the problem-solving process.
• Past successes have shown that expert systems are good at strategic goal setting,
planning, design, decision making, quality control and monitoring, and diagnosis.
• Applications of expert systems and artificial intelligence include credit granting and loan
analysis, catching cheats and terrorists, budgeting, games, information management
and retrieval, AI and expert systems embedded in products, plant layout, hospitals and
