Abstract:
A large number of expert systems require the use
of forward chaining or data driven inference. Rulebased
systems are really only feasible for problems
for which any and all knowledge in the problem area
can be written in the form of IF-THEN rules. In this
paper, Forward Chaining Reasoning Method is used
to diagnose chest pain cases that can be caused by
whether heart, lungs or gastrointestinal diseases. In
our system, chest pain symptoms, signs and
laboratory investigations are given as inputs, and it
will run as data-driven process and find the goal by
depth first search and make decision among nine
diseases. Firstly, the causes of diseases (heart, lungs
or gastro intestine) are analyzed by applying
Forward Chaining Method to discriminate the
underlying causes of chest pain. At last, the severity
(stage) of diseases can be defined by using Rule-
Based System.
