(This article was first published on Small World, and kindly contributed to R-bloggers) Until now I've always used randomly generated graphs which was completely fine but I've always wanted to use a real graph at some point.

The Potential of Social Network Analysis in Intelligence

Within its limits, SNA can be applied to identify individuals or organizations within a network, generate new leads and simulate flows of information or money throughout a network.

Like every analytic technique, SNA has great utility for the right question. Within its limits, SNA is unmatched and can be usefully applied to identify key individuals or organizations within a network, generate new leads and simulate the flows of information or money throughout a network.  SNA, however, remains just an answer, not the answer.  Used inappropriately or without a full understanding of the limits of the method and analysts will only be finding new and more technically sophisticated ways to fail.  That, then, is the primary job of the modern day analyst: making the judgment call of which techniques to use and when.  Equally as important as knowing when to use SNA is knowing when not to use it.

Libor: The Spider Network

The Libor manipulation scandal has ensnared at least 17 financial institutions and 22 individuals in a wide-ranging investigation spanning 11 countries and four continents. So far, it has netted at least $5 billion in penalties, with more on the way. Below, we've taken the most complete list of allegedly involved parties, compiled by WSJ reporters and editors, and mapped an extensive web of 298 reported connections that reveals the depth of the alleged conspiracy. Connections do not represent allegations of wrongdoing. The Journal has attempted to contact every institution and individual mentioned in this graphic. Their comments, if any, are included.

Tracking Two Known Terrorists

Twelve years ago, in 2001, the U.S. Government knew very little about mapping terrorist networks. Social Network Analysis [SNA] is a mathematical method for mapping and measuring human networks. SNA helps us 'connect the dots'.

Epidemics on social networks

Since its first formulations almost a century ago, mathematical models for disease spreading contributed to understand, evaluate and control the epidemic processes.They promoted a dramatic change in how epidemiologists thought of the propagation of infectious diseases.In the last decade, when the traditional epidemiological models seemed to be exhausted, new types of models were developed.These new models incorporated concepts from graph theory to describe and model the underlying social structure.Many of these works merely produced a more detailed extension of the previous results, but some others triggered a completely new paradigm in the mathematical study of epidemic processes. In this review, we will introduce the basic concepts of epidemiology, epidemic modeling and networks, to finally provide a brief description of the most relevant results in the field.

NodeXL new version

1.0.1.251 (2014-01-14)

Bug fix: If you attempted to import a Twitter network on January 14, 2014 or later, you would get an error message that included the text "The remote server returned an error: (403) Forbidden."It now takes significantly less time to import a graph from the NodeXL Graph Server. (This is a server-side change, so you don't need version 1.0.1.251 to notice the difference.)Graphs imported from the NodeXL Graph Server now include vertices for people who were replied to or mentioned by the people who tweeted the specified term but who didn't tweet the term themselves. (Note 1: Collection of the additional vertices started on 2013-08-21. Networks that span earlier datesmight include some additional vertices if they happen to already be in the collection database. Note 2: This is a server-side change, so you don't need version 1.0.1.251 to notice the difference.)
