EXPERT SYSTEM
Expert system is a computer system
that replicates what a human usually does as an expert. It did its job just
like how the experts did their jobs with the same knowledge. It’s amazing how a
system can mimic the knowledge of an expert. Expert system is used in:
•
diagnoses human illnesses
•
make financial forecasts
•
schedule routes for delivery vehicles
•
X-Ray diagnosis
Steps for setting up an expert system:
•
Interview the expert about the things required
in the expert system
•
Knowledge base, rules base and inference engine
is designed and created
•
User interface is also created
•
The expert system is now tested whether it
qualifies or not
•
Lastly, asking about the opinion of the experts
about what do they think about the expert system.
Advantages
•
Efficient
•
Will never get tired
•
Expert advice is available at all times which
means that even without the ‘real’ expert, the work still can be done
Disadvantages
•
Still not as good as the ‘real’ experts
•
Uncreative solutions
•
A narrow range of knowledge
Knowledge Base
Knowledge base is the base
where the experts give the information inputs. All the information needed is
stored here.
Inference Engine
Inference engine is where
the problems are solved according to the information provided by the experts.
Here is where the user’s questions meet the expert’s conclusion/information.
Rules Base
Rules
base is made up of inference rules which are used by the inference engine to
draw conclusions. They closely follow human-like reasoning.
