Efficiently counting complex multilayer temporal motifs in large-scale networks

October 6, 2019 network science
In a new paper titled “Efficiently counting complex multilayer temporal motifs in large-scale networks” we detail our approach to counting multilayer temporal motifs in networks with partial timing. The code (see Bitbucket) builds upon the well-known Stanford Network Analysis (SNAP) package. H.D. Boekhout, W.A. Kosters and F.W. Takes, Efficiently Counting Complex Multilayer Temporal…

The structure of criminal discussion forum networks on the dark net

December 14, 2018 network science
As part of his MSc in Computer Science with Data Science specialization, Alain Fonhof analyzed real-world network data sets collected from online discussion forums on the dark net. It turns out that network centrality measures can succesfully identify and characterize key players on the forum, distinguishing automatically between regular users,…

A community-aware approach for detecting network anomalies

December 12, 2018 network science
Network anomalies can for for example be spammers in communication networks, intruders in physical network systems or bots on social media. Master student Thomas Helling developed a new algorithm for finding such spammers, taking the awareness of nodes with respect to the community structure of the network, into account. Thomas…
