Results and Analysis:
Project description:
I’ve developed a new xml labelling scheme which tackles the issue of re-labelling when inserting new nodes to XML document.. However, the scheme called (GroupBased) and it was tested against (DDE) scheme (Dynamic Dewey Labelling Scheme).. I’ve tested the scheme from different aspect as follow:
1) Initial Labelling time and size
2) Determining Different Relationships
This experiment measured the time needed to calculate the six relationships between two nodes using their labels.( Order, Level, Ancestor/Descendant, Parent/Child, Sibling and Lowest common ancestor) on static document (no insertion occurred) & (after insertion)
3) 19 queries were tested prior and after insertion.
4) how the scheme handle different type of insertion namely:
Uniform Insertions
The uniform insertions refer to the insertion of a new node between two consecutive nodes..
Ordered Skewed Insertions
This type of insertion refers to the process of inserting before or after a particular node repeatedly.
Random Skewed Insertions
This type of insertion refers to randomly inserting between two nodes; ‘xml2.xml’ was used in this experiment.
However, at each point in every experiment the test was run (20 times) and the average was taken to draw the graph as you will see in (Ch.7 document) however, I’ve been asked to use (R statistics) to show Boxplots and then calculate the significance of the results using the Wilcoxon rank-sum test..
I have TWO different tasks for you :
First: Edit the (Ch.7) doc .. and include in it somewhere that each point in the presented results is the resulted average of (20 run) and add introduction on the boxplot technique and justify the use of it (convince the reader and support your writing with references) then you should also briefly explain the Wilcoxon rank-sum test and why it is chosen to test the results ..
Second Task: beside the (Ch7.doc) I will also upload to you the box plots figures (BoxPlots.pptx) as on each figure you’ll see the (p-value) which is the result of the Wilcoxon rank-sum test..
