13.4 Application of Expert System

Expert systems are designed and created to facilitate tasks in the fields of accounting, medicine,
process control, financial service, production, human resources etc. Indeed, the foundation of a
successful expert system depends on a series of technical procedures and development that may
be designed by certain technicians and related experts.

Example: A good example of application of expert systems in banking area is expert
systems for mortgages. Loan departments are interested in expert systems for mortgages because
of the growing cost of labour which makes the handling and acceptance of relatively small loans
less profitable.
They also see in the application of expert systems a possibility for standardized, efficient handling
of mortgage loan, and appreciate that for the acceptance of mortgages there are hard and fast
rules which do not always exist with other types of loans. While expert systems have distinguished
themselves in AI research in finding practical application, their application has been limited.
Expert systems are notoriously narrow in their domain of knowledge – as an amusing example,
a researcher used the “skin disease” expert system to diagnose his rust bucket car as likely to
have developed measles and the systems were thus prone to making errors that humans would
easily spot. Additionally, once some of the mystique had worn off, most programmers realized
that simple expert systems were essentially just slightly more elaborate versions of the decision
logic they had already been using.
Therefore, some of the techniques of expert systems can now be found in most complex programs
without any fuss about them.

Example: An example, and a good demonstration of the limitations of, an expert system
used by many people is the Microsoft Windows operating system troubleshooting software
located in the “help” section in the taskbar menu.

Obtaining expert/technical operating system support is often difficult for individuals not closely
involved with the development of the operating system. Microsoft has designed their expert
system to provide solutions, advice, and suggestions to common errors encountered throughout
using the operating systems.

Example: For example, the computer baseball games Earl Weaver Baseball and Tony La
Russa Baseball each had highly detailed simulations of the game strategies of those two baseball
managers. When a human played the game against the computer, the computer queried the Earl
Weaver or Tony La Russa Expert System for a decision on what strategy to follow. Even those
