Abstract:
Nowadays, many Rule-Based Expert
Systems have been proposed and almost all of
them assume “IF-THEN” rules. The process of
matching rules is performed by the data-driven
approach, Forward Chaining method, in the Rule-
Based Expert System. As the rules and data grow,
the time complexity of Forward Chaining method
is exponential. Because of this exponential
complexity, the system will perform quite slowly.
So reducing the processing time plays the
important role in Forward Chaining method. The
Rete algorithm provides for reducing the
processing time. This algorithm drops the time
complexity of Forward Chaining to linear rather
than exponential. It can improve the performance
of the system.This paper applies a Rule-Based
Expert System for helping to choose the specific
doctors according to the diseases. By applying this
system in android phones, the users can be easily
found the specific doctors in time.
