Overlapping Community Detection by Local Decentralised Vertex-centred Process

Maël Canu, Marie-Jeanne Lesot, Adrien Revault d'Allonnes

This paper focuses on the identification of overlapping communities, allowing nodes to simultaneously belong to several communities, in a decentralised way. To that aim it proposes…

Vertex-centred Method to Detect Communities in Evolving Networks

Maël Canu, Marie-Jeanne Lesot, Adrien Revault d'Allonnes

Finding communities in evolving networks is a difficult task and raises issues different from the classic static detection case. We introduce an approach based on the recent vertex…
