When time matters. SNA for 2-mode Temporal Covert Networks
Despite an increasing body of research on covert network dynamics, there is a lack of established consensus about how effectively covert networks operate and organise themselves. This is possibly due to the fact that the influence of external factors (i.e. shared risks, ideological/monetary covert group intentions), resulting in specific network structural characteristics, is not been actually quantified. As a consequence, the literature on CN presents controversial hypothesis contributing to increase the ambiguity in the field. In order to reduce this ambiguity and provide less controversial results, we propose a way to analyse covert networks by considering their two-mode network format. Our proposal goes in two directions. Firstly, it extends the use of dynamic line-graphs to two-mode networks. In this way, the time is directly incorporated into the matrix and provides a better representation of the evolution of actors’ participation in succeeding covert events. After illustrating our method, we present an example of its use on real-world data. Secondly, it relates to the debate on understanding of how individuals gather practical knowledge and expertise through hands-on experiences and by interacting with others. In such context we seek to quantify how channels of latent knowledge and expertise work in covert networks by proposing a way for measuring the transmission of knowledge and expertise. After the discussion of some theoretical implications, an example is used to demonstrate how this method works.
