Question 1

In decision making step of Knowledge Management process the _____ is used for decision making.

Accepted Answer

In the decision-making step of the Knowledge Management process, knowledge is used for making decisions. Knowledge is derived from information and data, and it provides the context, insights, and experience necessary for effective decision making.

Question 2

People are ultimately the ______ of knowledge.

Accepted Answer

People are referred to as "holders" of knowledge because they possess, retain, and can disseminate knowledge. This term captures the idea that individuals carry knowledge within them.

Question 3

_______ is a way of making a computer, a computer-controlled robot, or a software think intelligently, in the similar manner the intelligent humans think.

Accepted Answer

Artificial Intelligence (AI) is the field of computer science that aims to create machines that can think and act like humans.

Question 4

Data, information and past experience combined together are termed as _______.

Accepted Answer

Knowledge is the combination of data, information, and past experience. It represents a higher level of understanding and comprehension that is achieved by integrating these elements.

Question 5

JESS is an abbreviation for ________.

Accepted Answer

JESS stands for Java Expert System Shell, which is a rule engine and scripting environment written in Java.

Question 6

Business intelligence (BI) is a broad category of application programs which includes :

Accepted Answer

Business Intelligence (BI) encompasses a wide range of applications designed to analyze and manage data for business purposes. This includes decision support systems, data mining, and Online Analytical Processing (OLAP), among others.

Question 7

Which of following is not phase of decision making process

Accepted Answer

The phases of the decision-making process are Intelligence, Design, and Choice. Analysis is not considered a separate phase in this context.

Question 8

Decision support systems are essential for

Accepted Answer

Decision support systems are specifically designed to help managers make strategic decisions by analyzing large volumes of data and presenting it in a way that is easy to understand and interpret.

Question 9

Computer information system are most successful in providing information for:

Accepted Answer

Computer information systems are most successful in providing information for control decisions, as they are designed to monitor and manage operational processes efficiently.

Question 10

Which of the following describes the order in which customers are extracted from the line to be admitted to the service?

Accepted Answer

The answer of Which of the following describes the order...

Question 11

''To anticipate the value that a random variable will assume in the future or to estimate the likelihood of the future events'' is the purpose of?

Accepted Answer

Prediction is specifically aimed at forecasting future values of variables or the likelihood of future events based on current and historical data.

Question 12

If the distribution of values of the attribute aj is roughly normal, the z index based transformaltion generates values that are almost certainly within the range.

Accepted Answer

In a normal distribution, about 99.7% of the data falls within three standard deviations from the mean. The z-score transformation (z = (X - μ) / σ) standardizes data, so values typically range between -3 and 3 for a normal distribution.

Question 13

The purpose of ________ is to obtain a decrease in the number of distinct values assumed by one or more attributes.

Accepted Answer

The answer of The purpose of ________ is to obtain...

Question 14

PCA is

Accepted Answer

PCA stands for Principal Component Analysis, which is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components.

Question 15

Which of the following is required by K-means clustering?

Accepted Answer

K-means clustering requires a defined distance metric to measure the similarity between data points, a specified number of clusters to partition the data into, and an initial guess of cluster centroids to start the iterative process of optimization.

Question 16

Point out the wrong statement.

Accepted Answer

K-nearest neighbor (KNN) is a type of supervised learning algorithm used for classification and regression, whereas k-means is an unsupervised learning algorithm used for clustering. They serve different purposes and operate differently.

Question 17

Which of the following clustering requires merging approach?

Accepted Answer

Hierarchical clustering involves creating clusters that have a predetermined ordering from top to bottom. It uses a merging approach where each observation starts in its own cluster, and pairs of clusters are merged as one moves up the hierarchy.

Question 18

Which of the following gave rise to need of graphs in data analysis?

Accepted Answer

Graphs are used in data analysis for data visualization, communicating results, and aiding in decision-making, thus all of the mentioned reasons gave rise to the need for graphs.

Question 19

Which of the following is characteristic of exploratory graph?

Accepted Answer

The answer of Which of the following is characteristic of...

Question 20

Which of the following information is not given by five-number summary?

Accepted Answer

The answer of Which of the following information is not...
