Notes
Using the percentage of each class creates radar graph in order to show the relationship
ratio of contents of the articles in each class and use the relationship in each class of content
for calculating for point values in X-axis and Yaxis with Sum Vector equation as in Eq. (2)

X = value X-axis
Y = value Y-axis
P = Percentage of class

n = Classes Number
Using values of X and Y plot in the graph as Scatter plot in order to find the position of the
overall contents by equation 3.

X = value of X-axis

Benefit to Wikipedia in term of more reliable and clearer searching because Wikipedia is
online information resource and is open source which does not limit the editor and it open
for the users to check and edit the information by themselves. The good point is that the
information can grow very quickly but the bad point is that there is no editor or specialist
for checking the correction of all information in Wikipedia. Using DDC-MR for analyzing
the content in Wikipedia is able to compare the contents in Wikipedia with Text books in
the library within the group so that this can be checked for the accuracy of the information
and can ensure that the contents in Wikipedia is more reliable. In addition, DDC-MR will
make the connection of the contents in Wikipedia within the international standard instead
of the connection with only Keyword.

Questions
1. Critically analyse the above case.

2. Write down the case facts.
3. What do you infer from the case?
