BTT-Scope uses automatic social network detecting tools
using criteria such as; Degrees, Betweenness, and Closeness.
Degrees
Social network research is measure network activity
for a node by using the concept of degrees: the number
of direct connections a node has. In the kite network,
"Mr. Brown" has the most direct connections
in the network, making him the most active node in the
network. He is a “connector” in this network. Common
wisdom in personal networks is “the better it is, the
more connections you have”. This is not always so. What
really matters is where those connections lead to and
how they connect or unconnected. "Mr. Brown"
has connections only to "Mr. Red" in his immediate
cluster. He connects only those who are already connected
to each other.
Betweenness
While "Mr. Brown" has many direct ties, "Mr.
Anonym" has few direct connections, fewer than
the average in the network. But, he has one of the best
locations in the network, he is between two important
constituencies. He plays a 'broker' role in the network.
The good news is that he plays a powerful role in the
network, the bad news is that he is a single point of
failure. Without him, "Mr. Yellow" and "Mrs.
Dark" would be cut off from information and knowledge
in "Mr. Brown"'s cluster. A node with high
betweenness has great influence over what flows in the
network. A node like "Mr. Anonym" holds a
lot power over the outcomes in a network.
Closeness
"Mr. White" and "Mr. Brooks" have
fewer connections than "Mr. Brown", yet the
pattern of their direct and indirect ties allow them
to access all the nodes in the network more quickly
than anyone else. They have the shortest paths to all
"Mr. Red", they are close to everyone else.
They are in an excellent position to monitor the information
flow in the network. They have the best visibility into
what is happening in the network.
