Example program run for HICSS 47 Tutorial on Mining and Analyzing Social Media

1. Step 1A: .GDF File Opening

2. Step 1B: Change Type to Undirected

3. Step 1C: Open File (“OK”)

4. Step 1D: Random Layout of Network

5. Step 1E: Clicked “Center on Graph” button

6. Step 2A: Review Nodes in “Data Laboratory”

7. Step 2B: Review Edges in Data Laboratory

8. Step 3A: Select a “Layout” to improve the
visualized graph structure

9. Step 3B: Run “Force Atlas” layout procedure
setting “Repulsion strength” to 2000

10. Step 3C: “Stop” layout procedure

11. Step 3D: … producing a new, more easily
understood version of the graph

12. Step 3E: Click “T” to display node labels

13. Step 3F: Select “Label Adjust” from Layout(s)
To adjust label overlap

14. Step 4A: Click “Partition” in order to link
node colors to various attributes

15. Step 4B: Click “Refresh” button to
Access “partition parameter(s)”

16. Step 4C: Selected “age” parameter
from dropdown list

17. Step 4B: … then clicked “Apply” to
color nodes based on “age” group membership

18. Step 4E: … then clicked “T” to turn off the labels
in order to better inspect age distribution

19. Step 4F: Followed same procedure to
Display “sex” distribution

20. Step 4G: … and finally the “group” membership
distribution to better understand the Friendship structure

21. Step 5A: In analyzing various statistics for an Egocentric
network, “Ego” is usually deleted from node set

22. Step 5B: Ego has been eliminated, providing a clearer look
at the various subnetworks occupied by Ego’s Alters

23. Step 5C: As a second step in the analysis,
we click on the “Ranking” tab to access
various numerical parameters

24. Step 5D: In this analysis we are going to modify the “size”
(“diamond” icon) of the nodes to reflect
the various statistics of interests

25. Step 5E: At the moment, the only metric
that has been calculated is “Degree”
which we select and “Apply”

26. Step 5F: To calculate other statistics we simply click the
“Run” button next to the statistic name on the right

27. Step 5G: For many of these statistical runs,
dialog boxes appear describing the
statistics being calculated

28. Step 5H: The descriptions are usually followed
a report of the associated statistical results

29. Step 5I: Behind the scenes the selected statistics are also
being added to the Nodes table in the Data Laboratory [note:
I ran each of the statistics in the list on the Overview page]

30. Step 6A: Once a statistic has been run, the
name of the associated ranking will also
appear in the drop down selection list

31. Step 6B: In this case we are going to select
“Betweenness Centrality” for determining the size of
the nodes in the visual display

32. Step 6C: This is the result of that selection.

33. Step 6D: Now we click on “T” to add back the labels

34. Step 7A: Before we finish, we create a stylized rendition of
the graph by “Previewing” it. As an initial step to the
preview, we click the “Show Labels” box and click “Refresh”

35. Step 7B: This is the Previewed display

36. Step 7C. Finally, we return to the Node table in the
Data Laboratory and select “Export table”

37. Step 7D: This produces a dialog box for
selecting the attributes we want to
export. By default it’s all.

38. Step 7E: This is the final result which can be used for
further analysis.
