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.
