Question 1

The domain expert is the person with the expertise the expert system is trying to capture.

Accepted Answer

The term "domain expert" refers to the individual who possesses the specialized knowledge and experience within a particular field or domain that an expert system is designed to emulate or replicate.

Question 2

Assistive technology systems help people overcome disabilities and perform various tasks.

Accepted Answer

Assistive technology systems are designed to help individuals with disabilities perform tasks that might otherwise be difficult or impossible for them to accomplish. These systems can range from electronic devices that provide auditory or visual cues to help those with hearing or vision impairments to mobility tools that assist those with physical disabilities.

Question 3

Robotics involves developing mechanical or computer devices that can paint cars, make precision welds, and perform tasks that require a high degree of precision or are tedious or hazardous for humans.

Accepted Answer

Robotics indeed involves developing mechanical or computer devices capable of performing tasks that require precision, efficiency, or pose danger to humans.

Question 4

While gathering requirements for a system that assists tech support people, you create a list of conditions and the recommended responses. This list of conditions and responses can form the basis of a knowledge-base for a robotics system.

Accepted Answer

The answer of While gathering requirements for a system that...

Question 5

Although computers excel at numerical calculations, they are not as good at dealing with symbols and three-dimensional objects.

Accepted Answer

Computers are better at dealing with numerical calculations and data manipulation rather than symbolic reasoning and three-dimensional objects. This is because computers operate on binary code which represents numerical values in the form of 0s and 1s. They require specialized software and algorithms to deal with symbols and 3D objects.

Question 6

Expert systems use heuristics to arrive at conclusions or make recommendations.

Accepted Answer

Expert systems use heuristics, which are problem-solving strategies that may not always lead to a perfect solution, but can provide useful guidance and insights.

Question 7

A genetic algorithm can be used to search the vast resources of the Internet to find information on any topic.

Accepted Answer

A genetic algorithm is a problem-solving technique inspired by natural selection that is used to find optimal solutions to complex problems. It works by evaluating a population of potential solutions and selecting the ones that are most fit to survive and produce offspring. While it can be used to search large datasets or optimize complex systems, it cannot specifically search the Internet for information on any topic.

Question 8

Vision systems include hardware and software that permit computers to capture, store, and process visual images.

Accepted Answer

This is an accurate definition of vision systems.

Question 9

Expert system shells lessen the burden of programming, allowing nonprogrammers to develop and benefit from the use of expert systems.

Accepted Answer

Expert system shells provide pre-designed frameworks and interfaces that can be easily customized by nonprogrammers, reducing the need for extensive coding knowledge and making the development of expert systems more accessible.

Question 10

Artificial intelligence involves the development of machines and computer systems that can simulate human intelligence processes.

Accepted Answer

Artificial intelligence aims to replicate human intelligence through machines and computer systems.

Question 11

Learning systems allow a computer to change how it reacts to situations based on the feedback it receives.

Accepted Answer

Learning systems use machine learning algorithms to improve a computer's performance over time by adjusting its behavior based on feedback from past experiences. This allows the computer system to learn from its mistakes and make better decisions in the future.

Question 12

To avoid potential bottlenecks and delays in accurately applying and implementing changes in business rules, many organizations use business rule management software.

Accepted Answer

Business rule management software is designed to automate the capture, management, and execution of business rules, enabling organizations to apply changes quickly and accurately without the need for manual intervention. This reduces the risk of bottlenecks and delays that can occur when changes are made manually, helping organizations to be more agile and responsive to changing business needs.

Question 13

When audio files are played while they are being downloaded from the Internet, it is called streaming audio.

Accepted Answer

Streaming audio refers to playing audio files while they are being downloaded from the Internet, allowing for real-time playback without requiring the full file to be downloaded first.

Question 14

An expert system, using the explanation facility, can indicate all the facts and rules that were used in reaching a conclusion.

Accepted Answer

The explanation facility in an expert system allows it to provide a detailed explanation of how the system arrived at a specific conclusion, including all the facts and rules that were used.

Question 15

A user interface makes an expert system easier to develop and use.

Accepted Answer

A user interface can simplify the user interaction with the expert system by providing intuitive menus, forms, and controls that guide the user through the decision-making process. It can also facilitate the development of an expert system by enabling domain experts to create and refine rules and knowledge bases without requiring programming skills.

Question 16

The overall purpose of an inference engine is to seek information and relationships from the knowledge base and to provide answers, predictions, and suggestions similar to the way a human expert would.

Accepted Answer

The statement accurately describes the overall purpose of an inference engine.

Question 17

A perceptive system allows a machine to approximate the way a person sees, hears, and feels objects.

Accepted Answer

A perceptive system is designed to approximate human senses such as sight, hearing, and touch, in order to interpret and interact with the environment in a way that is more intuitive and natural for human users.

Question 18

An expert system can use a case-based solution process to develop the solution to a problem by finding cases stored in the knowledge base that are similar to the problem at hand and then modifying the solution to the cases to fit the current problem.

Accepted Answer

This statement is true. An expert system can use a case-based reasoning approach to find solutions to a problem by retrieving similar cases from the knowledge base and adapting them to fit the current problem. This process can be efficient and effective in solving complex problems that may not have a predetermined solution strategy.

Question 19

A group of people with common interests who come together to create, store, and share knowledge of a specific topic is known as a community of practice.

Accepted Answer

This is the definition of a community of practice.

Question 20

If Stan and Marcus, a new trainee at the manufacturing plant, are working together to resolve an issue on the line, they would be using joint problem solving as a means of transferring Stan's tacit knowledge to Marcus.

Accepted Answer

Joint problem solving involves collaboration between two or more individuals to solve a problem, with the goal of sharing knowledge and expertise. In this scenario, Stan would be sharing his tacit knowledge with Marcus through their joint problem solving efforts.
