Question 1

An internal test of an expert system whose purpose is to determine if the system uses the same reasoning process as the experts) used to build the system.&#10;A) validation&#10;B) verification&#10;C) reliability&#10;D) suitability

Accepted Answer

Verification is the process of checking that a software system meets specifications and that it fulfills its intended purpose. In the context of an expert system, verification would involve ensuring that the system's reasoning processes align with those of the human experts who designed it.

Question 2

Knowledge acquisition involves one or more experts and a&#10;A) systems analyst.&#10;B) knowledge engineer.&#10;C) knowledge designer.&#10;D) systems engineer.

Accepted Answer

Knowledge acquisition involves the participation of one or more domain experts and a knowledge engineer who helps to capture, validate, and transform the domain knowledge into an explicit and formal representation that can be used by a computer system. Systems analysts, knowledge designers, and systems engineers may be involved in later stages of the system development process, but they are not typically involved in the knowledge acquisition process.

Question 3

Encoding the knowledge extracted from an expert into a knowledge base.&#10;A) knowledge programming&#10;B) knowledge representation&#10;C) knowledge acquisition&#10;D) rapid prototyping

Accepted Answer

A

Question 4

An expert system with an empty knowledge base.&#10;A) expert system shell&#10;B) inference shell&#10;C) state space&#10;D) goal tree

Accepted Answer

An expert system with an empty knowledge base is called an expert system shell. It is a software framework for building expert systems that provides the basic infrastructure and functionality for knowledge representation, inference, and user interaction, but it does not contain any specific knowledge about a particular domain or problem.

Question 5

Write production rules for the following goal tree.&#10;

Accepted Answer

The answer of Write production rules for the following goal...

Question 6

The main components of an expert system include a Knowledge base, a user interface and&#10;A) a database&#10;B) an explanation facility&#10;C) an inference engine&#10;D) a constraint propagator

Accepted Answer

The knowledge base stores the domain-specific knowledge, while the user interface allows interaction between the system and user. However, for the system to make decisions and draw conclusions based on the knowledge base, an inference engine is required. This engine uses logic and rules to make decisions and is an essential component of an expert system. The explanation facility and constraint propagator are also important, but less fundamental components. Therefore, the best answer is C: an inference engine.

Question 7

Construct a goal tree using the following production rules. Assume the goal is g.

Question 8

Developing a rough version of a system that is suitable for testing.&#10;A) validating&#10;B) field reporting&#10;C) verifying&#10;D) prototyping

Accepted Answer

Developing a rough version of a system that is suitable for testing is essentially creating a prototype. Prototyping involves building an initial version of a system or product in order to gather feedback and identify any flaws or issues before fully developing and implementing the final version. Validating, field reporting, and verifying may be steps in the prototyping process, but they are not the primary action being taken in this scenario.

Question 9

Knowledge about knowledge is known as&#10;A) metaknowledge&#10;B) class knowledge&#10;C) structured knowledge&#10;D) classified knowledge

Accepted Answer

The term for knowledge about knowledge is commonly referred to as metaknowledge.

Question 10

The knowledge contained in a knowledge-based system&#10;A) contains the knowledge of one or more human experts.&#10;B) contains the knowledge of one or more intelligent agents.&#10;C) contains the knowledge of exactly one human expert.&#10;D) contains knowledge extracted from one or several sources.

Accepted Answer

The answer of The knowledge contained in a knowledge-based system&#10;A)...
