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.
Keywords: communication; complex networks; graph theory; node discovery; social networking; terrorism; terrorist social networks; simulation; performance evaluation; covert social networks.
