SNA - Theoretical foundations for statistical network analysis

Publication networks are useful scientometric indicators for « drawing » a scientific landscape by unveiling individual and/or thematic interactions. From a historical as well as sociological perspective, an important issue is to capture the dynamics of the corresponding graphs, this being especially true when we face the emergence of a new paradigm that aggregates, around new concepts, activities that were previously scattered in different fields. In exact sciences, a typical example of such an emergence is provided by « wavelets », a mathematical object that generalizes Fourier analysis and has led to numerous scientific and technological applications since their introduction in the mid-80’s. Basing the analysis on ideas of heterogeneous networks, communities detection and flow diagrams, we will present some results in this direction, with the two-fold objective of enlightening the origins of what has become a standard tool and a well-recognized keyword, and of evidencing the new organizations of the scientific landscape that have followed.   
Joint work with Pablo Jensen and Matteo Morini.
