The HiTS/ISAC Social Network Analysis Tool

We describe the Social Network Analysis Tool (SNATool)developed in the HiTS/ISAC (Highway to Security: Interoperability for Situation Awareness and Crisis Management) EU PASR (Preparatory Action for Security Research) project. The tool enables the construction of social networks from database sources using advanced filters on three different levels. The tool also allows visualization of the results for analysis purposes. The tool was demonstrated and evaluated in a scenario involving customs and police operators working to detect smuggling of dangerous substances and also for detecting and preventing a terrorist attack.
