This paper proposes a new framework, based on graph database theory, for encoding complex data on covert networks, mapping their structure, and conducting a sensitivity analysis. The framework is then applied to reconstruct the terrorist network of the 2015–2016 attacks in Paris and Brussels, and related plots in Europe by the Islamic State group. The resulting network was found to be qualitatively different from the ideologically-related Al-Qaeda network, having a lower secrecy and a lower mean degree, under different network-generating assumptions.
