A2 Expert Systems Retrieval Practice

What is an expert system primarily used for?

• Replacing all human experts in an organization

• Narrow field of knowledge called the knowledge domain

• Making decisions autonomously

• General knowledge across multiple domains

What does the knowledge base of an expert system contain?

• Only heuristic knowledge

• Only rules

• Facts, rules, and heuristics

• Only factual knowledge

What is the role of the inference engine in an expert system?

• To provide a user interface

• To interrogate the knowledge base and draw conclusions

• To replace human experts

• To store facts and rules

Which of the following is NOT a type of user interface mentioned?

• Command line

• WIMP

• Voice recognition

• GUI

What is a key characteristic of heuristic knowledge?

• Based on human experience and intuition

• Always accurate and precise

• Only used in financial systems

• Derived purely from logic

What is the purpose of fuzzy logic in expert systems?

• To replace the inference engine

• To use strict true or false values

• To store factual knowledge

• To make decisions with incomplete or uncertain data

Who is responsible for obtaining information for the knowledge base?

• The knowledge engineer

• The user interface

• The inference engine

• The end-user

What is an expert system shell?

• A database management system

• A type of user interface

• A software development environment for creating expert systems

• A physical casing for the system

What is the main advantage of using expert system shells?

• They eliminate the need for human experts entirely

• They provide a built-in inference engine and can be configured for specific applications

• They allow for the creation of systems without any knowledge

• They are cheaper than traditional software

What is the role of the user interface in an expert system?

• To replace the knowledge engineer

• To enable users to input queries and receive solutions

• To process and draw conclusions from data

• To store and manage the knowledge base
