35
Q

Expert systems

A

It is an AI-based computer program that emulates the decision-making capabilities of human experts. It uses knowledge and rules to provide accurate advice or solutions in a specific domain.

36
Q

an expert system includes ?

A

a user interface
explanation system
Inference engine
knowledge base
rule base

37
Q

user interface in a expert system

A

the only thing that end user can see
allows the user to interact with the system
asks Y/N questions
displays results

38
Q

explanation system

A

-Informs the user of the reasoning behind the expert system’s conclusions
-It will supply a conclusion and any suggested actions to take
-It will also give the percentage probability of the accuracy of its conclusions

39
Q

inference engine

A

-The main processing element of the system
-It acts like a search engine examining the knowledge base
-Responsible for gathering information
-This is the problem-solving part of the system
-Attempts to use information gathered from the user to find a matching object

40
Q

knowledge base

A

-It is a repository of facts
-stores all the knowledge about an area of expertise
-a collection of objects and their attributes

41
Q

rule base

A

-The rules base is a set of inference rules.
-Used by the inference engine to draw conclusions
-They follow logical thinking

42
Q

OMR

A

Optical Mark recognition

43
Q

advantages of OMR

A

-very fast way of inputting the results of a survey
-more accurate than keying in data
-more accurate than OCR methods

44
Q

disadvantage of OMR

A

-designing the forms is a very complex job
-there can be problems if they haven’t been filled correctly
-often only work with black pens or pencils

45
Q

OCR

A

Optical Character Recognition

46
Q

advantages of OCR
they use Automatic Number Plate Recognition (ANPR) systems in the example

A

There is no need to employ a car park or security guards.
It’s a much faster system than checking a ticket at the exit.
It can be used as a security system to prevent illegal parking.
It can be used to analyze driver behaviour.
It can be used in inner-city congestion charging systems.

47
Q

disadvantage of OCR
they use Automatic Number Plate Recognition (ANPR) systems in the example

A

A lack of manned security car park surveillance could lead to vandalism.
There could be an invasion of privacy due to recording drivers’ number plates.
Damaged or very dirty number plates will not be recognized.
The ANPR system only recognizes the number plate and not the car so that a car can be fitted with a cloned number plate, thus bypassing car park security, for example.
