Exam 11: Automated Decision Systems and Expert Systems

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

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?

Knowledge rules, or ________ rules, state all the facts and relationships about a problem.

An ________ infers situation descriptions from observations, and explains observed data by assigning them symbolic meanings that describe the situation.

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

Expert systems mimic the reasoning process of ________ experts in order to solve problems.

After an ES system is built, it must be evaluated in a two-step process. The first step, ________, ensures that the resulting knowledge base contains knowledge exactly the same as that acquired from the expert.

________ blocks in the Corvid ES determine(s) how the system interacts with the user, including the order of execution and the user interface.

________ (or reasoning) is the process of using the rules in the knowledge base along with the known facts to draw conclusions.

The critical component of a knowledge refinement system is the self-learning mechanism that allows it to adjust its knowledge base and its processing of knowledge based on the evaluation of its recent past performances.

________ express belief in an event (or a fact or a hypothesis) based on the expert's assessment.

After an ES system is built, it must be evaluated in a two-step process. The second step, ________, ensures that the system can solve the problem correctly.

In the Corvid ES shell, ________ blocks are the decision rules acquired from experts.

Rules used in automated decision systems (ADS) can be derived based on experience.

The accumulation, transfer, and transformation of problem-solving expertise from experts or documented knowledge sources to a computer program for constructing or expanding the knowledge base is known as ________.

What is knowledge engineering?

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?
