dynamics
"A basic toolbox for the analysis of dynamics of growing networks" (2005) (with C. Magnien and M. Mariadassou) introduces very simple statistical tools relevant for dynamic network study - i.e., tools differing from those used in classical static analysis. See also the paper "Generalized Preferential Attachment: Towards Realistic Social Network Models", dealing in particular with socio-semantic networks.
