LSCPM: communities in massive real-world Link Streams by Clique Percolation Method

no code implementations21 Aug 2023 Alexis Baudin, Lionel Tabourier, Clémence Magnien

We present a novel algorithm that adapts CPM to link streams, which has the advantage that it allows us to speed up the computation time with respect to the existing DCPM method.

Faster maximal clique enumeration in large real-world link streams

1 code implementation1 Feb 2023 Alexis Baudin, Clémence Magnien, Lionel Tabourier

We take this idea as a starting point to propose a new algorithm which matches the cliques of the instantaneous graphs formed by links existing at a given time $t$ to the maximal cliques of the link stream.

Clique percolation method: memory efficient almost exact communities

1 code implementation4 Oct 2021 Alexis Baudin, Maximilien Danisch, Sergey Kirgizov, Clémence Magnien, Marwan Ghanem

Automatic detection of relevant groups of nodes in large real-world graphs, i. e. community detection, has applications in many fields and has received a lot of attention in the last twenty years.

Computing Betweenness Centrality in Link Streams

no code implementations12 Feb 2021 Frédéric Simard, Clémence Magnien, Matthieu Latapy

Betweeness centrality is one of the most important concepts in graph analysis.

Stream Graphs and Link Streams for the Modeling of Interactions over Time
