Accepted Answer

The answer of In the sport talents identification case study,...

Question 2

Which module is missing from most expert systems?

Accepted Answer

The missing module from most expert systems is the knowledge refinement subsystem which is responsible for acquiring new knowledge and updating the knowledge base subsystem. The user interface subsystem (A), knowledge base subsystem (B), and inference engine (C) are typically included in most expert systems.

Question 3

Which of the following is NOT a stage of knowledge engineering?

Accepted Answer

The stage of knowledge consolidation is not typically seen as one of the primary stages of knowledge engineering. The other three stages (knowledge representation, knowledge acquisition, and knowledge validation) are widely recognized as important stages in the creation of knowledge-based systems.

Question 4

In the InterContinental Hotel Group case study, the mathematical model used to increase profits was based on

Accepted Answer

The InterContinental Hotel Group case study utilized an optimization model that incorporated multiple variables to increase profits. This approach allowed for a more comprehensive analysis and adjustment of various factors to optimize pricing and booking strategies.

Question 5

Which tool would be best to use when there is a need to very rapidly and cheaply develop a rule-based expert system?

Accepted Answer

An ES shell (expert system shell) is specifically designed for the development of rule-based expert systems. It provides a pre-built framework for creating rules and inference engines, making it a quick and cost-effective option. LISP and Prolog languages and C++ can be used to develop expert systems, but they require more expertise and time investment. ASP.NET is not typically used for expert system development.

Question 6

In the heart disease diagnosis case study, what was a benefit of the SIPMES expert system?

Accepted Answer

The answer of In the heart disease diagnosis case study,...

Question 7

Which category of expert systems that includes weather forecasting and economic/financial forecasting?

Accepted Answer

Prediction expert systems are designed to forecast future events, trends or outcomes based on historical data and other relevant information. Examples of prediction ES include weather forecasting and economic/financial forecasting.

Question 8

In the chemical, biological, and radiological agents case study, the CBR Advisor program had all the following features EXCEPT

Accepted Answer

The CBR Advisor program was not available online to the general public, but rather to authorized users such as emergency responders and health care professionals.

Question 9

How does an expert system differ from conventional systems?

Accepted Answer

Expert systems are designed to make decisions based on knowledge and rules, in contrast to conventional systems which primarily handle quantitative data. This makes it easier for expert systems to handle qualitative data.

Question 10

Using certainty factors, a rule declares that IF competition is strong, CF = 70 AND margins are above 15% CF = 100 THEN sales demand will decline. If both conditions are true, what is the CF of the conclusion?

Accepted Answer

The CF of the conclusion will be the minimum of the two CFs of the antecedents, which is 70%. Therefore, the correct answer is B.

Question 11

It is difficult to acquire knowledge from experts for all the following reasons EXCEPT

Accepted Answer

The statement "many business areas have no identifiable experts" suggests that this is not a reason why it is difficult to acquire knowledge from experts. The other options have valid explanations:

A) Experts may not be able to put into words how they conduct their work, making it difficult to transfer knowledge. 
B) Testing and refining of knowledge is complex and difficult, which can lead to incomplete or inaccurate knowledge transfer. 
D) Experts often change their behavior when observed, making it difficult to fully comprehend their knowledge and techniques.

Question 12

The MYCIN Expert System was used to diagnose bacterial infections using

Accepted Answer

The MYCIN Expert System was based on a set of over 500 rules regarding bacterial infections, making choice B the correct option. The system was not a simulation model, optimization model or inferior to human experts.

Question 13

What does self-knowledge in an expert system (ES) mean?

Accepted Answer

The answer of What does self-knowledge in an expert system...

Question 14

Using certainty factors, a rule declares that IF competition is strong, CF = 70 OR margins are above 15% CF = 100 THEN sales demand will decline. If both conditions are true, what is the CF of the conclusion?

Accepted Answer

When combining certainty factors (CFs) with an OR condition, you take the maximum CF of the conditions. Since the CFs are 70 and 100, the maximum is 100, leading to the conclusion that sales demand will decline with a CF of 100%.

Question 15

In the Giant Food Stores case study, the new pricing model deployment system included all the following features EXCEPT

Accepted Answer

The new pricing model deployment system did not require more staff to make pricing changes. In fact, it streamlined the process by automating many aspects of it.

Question 16

Who are automated decision systems (ADS) primarily designed for?

Accepted Answer

Automated decision systems (ADS) are primarily designed for frontline workers who must make decisions rapidly, as these systems can quickly process data and provide immediate recommendations or actions.

Question 17

Question 18

What would explain why a divorce attorney in New York City may not be considered an expert in Beijing, China?

A divorce attorney's expertise in New York City is based on the laws and practices of New York and the United States, which may differ significantly from those in Beijing, China. This makes their expertise less applicable or recognized in a different legal system and cultural context.

Question 19

In the Clinical Decision Support System case study, what was the system's output?

Accepted Answer

The case study does not mention any specific output related to a diagnosis or referral to specialists. However, it does mention that the Clinical Decision Support System provided a treatment and rehabilitation plan for the patient based on their individual characteristics and history.

Question 20

Revenue management systems modify the prices of products and services dynamically based on

Accepted Answer

Revenue management systems use business rules, demand, and supply as the factors to modify prices. Intuition and competition may also play a role, but they are not the primary factors for decision making in revenue management systems.
