Analyzing covert social networks

Science Daily notes a social networking paper that sounds interesting.

“A new approach to analyzing social networks, reported in the current issue of the International Journal of Services Sciences, could help homeland security find the covert connections between the people behind terrorist attacks. The approach involves revealing the nodes that act as hubs in a terrorist network and tracing back to individual planners and perpetrators.”

Abstract: This paper addresses a method to analyse the covert social network foundation hidden behind the terrorism disaster. It is to solve a node discovery problem, which means to discover a node, which functions relevantly in a social network, but escaped from monitoring on the presence and mutual relationship of nodes. The method aims at integrating the expert investigator’s prior understanding, insight on the terrorists’ social network nature derived from the complex graph theory and computational data processing. The social network responsible for the 9/11 attack in 2001 is used to execute simulation experiment to evaluate the performance of the method.
