ASSIGNMENT 1
Answer ALL questions in the answer sheets provided.
1. Explain three advantages of AI over Natural Intelligence (NI).
 AI is permanent whereas natural intelligence is perishable
 AI offers ease of duplication whereas transferring a body of
knowledge from one person to another is a lengthy process
 AI can be less expensive than natural intelligence
2. AI can be classified into several fields. List two of the fields.
 Expert System
 Natural Language Processing
 Speech (Voice) Understanding
 Robotics and Sensory Systems
 Computer Vision
 Intelligent Computer-Aided Instruction (ICAI)
 Case-based Reasoning / Neural Networks
3. List down two differences between the conventional systems and the expert
systems.
Conventional Systems
Knowledge and processing are
combined in one sequential program
Programs do not make mistakes (only
programmers do)
Do not usually explain why input data
are needed or how conclusions were
drawn
The system operates only when it is
completed
Execution is done on a step-by-step
(algorithmic) basis
Needs complete information to operate
Expert Systems
Knowledge base is clearly separated
from the processing (inference)
mechanism (knowledge rules are
separated from the control)
Program may make mistakes
Effective manipulation of large
databases
Representation and use of data
Explanation is a part of most expert
systems
The system can operate with only a
few rules (as a first prototype)
Execution is done by using heuristics
and logic
Can operate with incomplete or
uncertain information
Effective manipulation of large
knowledge bases
Representation and use of knowledge

Efficiency is a major goal
Easily deals with quantitative data
Effectiveness is a major goal
Easily deals with qualitative data
(Any two of the above)
4. What are the tools for developing an Expert System?
 Use a programming languages (usually AI language)
 Use a shell
 Use an AI environment (or toolkit)
5. Draw the diagram to differentiate between human expert and expert system
problem solving.
