.................................... sites on the Web.

12.7 Summary

 An expert system is nothing but a computer program or a set of computer programs which
contains the knowledge and some inference capability of an expert, most generally a
human expert, in a particular domain.

 An expert system is a computer system which emulates the decision-making ability of a
human expert.

 Expert systems are necessitated by the limitations associated with conventional human
decision-making processes.
 Expert system development can be modeled as a spiral, where each circuit adds more
capabilities to the system.
 Fuzzy Logic Systems are defined as computer-based systems that can access data that are
incomplete or only partially accurate.
 Neural networks are defined as computing systems modeled on the human brain’s mesh-
like network of interlinked processing elements, known as neurons.

 Genetic algorithm software accesses Darwinian (survival of the fittest); randomizing, and
other mathematical functions to create an evolutionary process that can capitulate
increasingly better solutions to a problem.

 An intelligent agent is a software replacement for an end user or a process that accomplishes
a specified requirement or activity.

12.8 Keywords

Expert System: An Expert System is a computer program that possesses or represents knowledge
in a particular domain, has the capability of processing/manipulating or reasoning with this
knowledge with a view to solving a problem, giving some achieving or to achieve some specific
goal.
