Discovering sets of key players and analyzing their
influence is also one of the vital problems in social network
analysis. In this phenomenon some nodes can have
intrinsically higher influence than others due to network
structure. The global measures are often associated with
nodes in the network rather than edges. The edges are rather
associated with the strength of relationships between nodes.
[13] discusses the importance of Influential analysis. We
would consider the edge based and node based measures to
analyze the influence, such as determining the pivotal nodes
with top tie strengths as shown in Figure. 6. In this figure,
we depict a sample snapshot of 104 top frequent edges using
[6] algorithm from an evolving call network at the end of
31 days. The above graph is illustrated using FruchtermanReingold
layout algorithm [14]. We can observe few dense
connections in the center of the graph and many sparsely
connected nodes at the periphery. Additionally, we propose
to analyze the cascading behavior and strength of mutual
exchange of information between nodes.
