the social structure between actors,
mostly individuals or organizations. It
indicates the ways in which they are
connected through various social
familiarities ranging from casual
acquaintance to close familiar bonds.

Social Network Analysis
We measure Social Network in terms of:
1. Degree Centrality:
The number of direct connections a node has. What really matters is where
those
connections lead to and how they connect the otherwise
unconnected.
2. Betweenness Centrality:
A node with high betweenness has great influence over what flows in the
network indicating important links and single point of failure.
3. Closeness Centrality:
The measure of closeness of a node which are close to everyone else.
The pattern of the direct and indirect ties allows the nodes any other node in
the network more quickly than anyone else. They have the shortest paths to
all others.
