1. A method comprising the steps of: analyzing a plurality of exchanged messages by an analysis mechanism residing in a memory coupled to at least one processor; constructing a social network based on said plurality of exchanged messages; extracting a plurality of concepts from said plurality of exchanged messages based on said social network; creating a semantic network from said plurality of concepts; displaying a visual representation of said social network on a monitor, thereby creating a social network visualization said step of displaying a visual representation of said social network on a monitor comprising the step of displaying at least two of: a layered digraph representing said social network; a force directed graph representing said social network; a circular layout graph representing said social network; a radial view graph representing said social network; and a time based message graph, said time based message graph comprising a plurality of nodes, wherein each node represents a message exchanged between at least two entities; and displaying said plurality of concepts on said monitor in concert with said social network visualization.
