MultiScale Modeling of Radical and Counter-Radical Islamic Organizations

In this paper we utilize an efficient sparse inverse covariance matrix (precision matrix) estimation technique to identify a set of highly correlated discriminative perspectives between radical and counter-radical Islamic organizations. We develop a ranking system that utilizes ranked perspectives to map Islamic organizations on a set of socio-cultural, political and behavioral scales based on their web corpus. We create a gold standard ranking of these organizations through an expertise elicitation tool. We compute expert-to-expert agreements, and present experimental results comparing the performance of the QUIC based scaling system to another baseline method for 26 Islamic organizations in UK. The QUIC based algorithm not only outperforms the baseline method, but it is also the only system that consistently performs at area expert-level accuracies for all scales.
