Cliques in Social Media
In the Raptors fan page data, all fans are linked to each other if they
comment on the same post, so cliques are rampant. Isolating the largest

cliques and, provided they don't overlap, there is a way to bring them into
Gephi for visualization. It isn't pretty, but it works.
Return to the NodeXL worksheet where you enhanced the data with topics.
In the graph Analysis ribbon group, select Groups
⇒
Group by Motif. Motifs
are not relevant here, but what will be relevant are the groups produced.
In the options that appear, uncheck the fan and D-connector options, and
specify a minimum size of 15 for cliques. The two
Group
worksheets will
be populated with the results. Now comes the tricky part. To get the cliques
into Gephi, you will need to transform them from their current form in the
Group Vertices
worksheet to a new form in the
Vertices
worksheet,
which requires a bit of Excel wizardry.
