Analyzing the Terrorist Social Networks with Visualization Tools

Analysis of terrorist social networks is essential for discovering knowledge about the structure of terrorist organizations. Such knowledge is important for developing effective combating strategies against terrorism. Visualization of a network using a 2D graph can greatly facilitate the inspection of the global structure of the network with the support of the social network analysis techniques. However, its usefulness becomes limited when the size and complexity of the network increase. In this work, we study the use of two interactive visualization techniques in the visualization of complex terrorist social networks: fisheye views and fractal views. Both techniques facilitate the exploration of complex networks by allowing a user to select one or more focus nd dynamically adjusting the graph layout and abstraction level to enhance the view of regions of interest. Combining the two techniques can effectively help an investigator to recognize patterns previously unreadable in the norma...
