Question 8

_____ refers to discovering groups of customers that are in some way or another "similar," without using any a priori and known structures.

Accepted Answer

Clustering refers to discovering groups of entities (like customers)that are in some way or another "similar," without using any a priori and known structures.

Question 9

Which of the following is the science of making machines imitate human thinking and behavior?

Accepted Answer

Artificial intelligence is the science of making machines imitate human thinking and behavior.

Question 10

Which of the following is an artificial intelligence system that applies reasoning capabilities to reach a conclusion?

Accepted Answer

An expert system,also called a knowledge-based system,is an artificial intelligence system that applies reasoning capabilities to reach a conclusion.

Question 11

The word "Mercury" can refer to an element,a planet,an automobile brand,a record label,a NASA manned-spaceflight project,a plant,and a Roman god.This is an example of ____.

Accepted Answer

Disambiguation is the process of determining the specific meaning of a named entity recognition.For example here,"Mercury" may refer to many things.

Question 12

Which of the following intelligence-related tasks attempts to evaluate historical,known data to derive structures and inferences that can be applied to newly gathered or future data?

Accepted Answer

Classification is also known as prediction (although the two are not the same).Here,you attempt to evaluate historical,known data to derive structures and inferences that can be applied to newly gathered or perhaps future data.

Question 13

_____ is a process of using statistical,artificial intelligence,and linguistic techniques to convert information content in surveys,e-mails,blogs,and social media into structured information.

Accepted Answer

Text analytics is a process of using statistical,artificial intelligence,and linguistic techniques to convert information content in textual sources-like surveys,e-mails,blogs,and social media-into structured information.

Accepted Answer

A prediction indicator is a specific measurable value based on an attribute of the entity under consideration.

Question 15

If you were using your PDA and it was analyzing and reacting to every word you typed on the pad,what type of system would you be using?

Accepted Answer

Neural networks are widely used for visual pattern and speech recognition systems.If you've used a tablet PC that deciphered your handwriting,it was probably a neural network that analyzed the characters you wrote.

Question 16

An expert system is usually built for a specific application area called a(n)____.

Accepted Answer
