Home Institution : CNRS | Position : Full Tenured Researcher at CNRS | Disciplines : Sociology |


Dr Camille Roth is a Tenured Researcher in Computer Science at CNRS, after having also been Associate Professor of Sociology at Sciences Po and Assistant Professor of sociology at the University of Toulouse. He holds a PhD in social sciences from Ecole Polytechnique (2005), with a dual background in maths and physics (Ecole des Ponts, 2002) and cognitive science (EHESS, 2002). While at CMB, he will focus on socio-semantic networks, public space dynamics especially in the context of online communities, and more broadly social complex system modeling.

He has been global or local PI for several multi-institution research projects combining social and formal sciences, both at the national and European level (including an ERC Consolidator Grant, 2018-23) and currently supervises a team of several doctoral and post-doctoral researchers. He has authored more than 50 peer-reviewed publications. He is also associate member of CAMS (Centre d'Analyse et de Mathématique Sociales, CNRS-EHESS), ISCPIF (Institut des Systèmes Complexes - Paris Ile de France), and CRESS (Dept of Sociology, U. Surrey).

ERC Socsemics - Socio-Semantic Bubbles of Internet Communities

More precisely, SOCSEMICS aims at addressing a series of fundamental questions pertaining to the existence, structure and dynamics of such bubbles in digital public spaces: how to define and appraise them empirically, how do they form and emerge, which types of topics, claims and actors are mobilized in which of them, which bridges or bottlenecks may interconnect them and, at a higher level, what is the meta-structure of bubbles and what kind of qual-quantitative studies may result from this new type of approach.

In practice, SOCSEMICS will address three current challenges:

  • (i) developing a comprehensive theory of reinforcing and self-sustaining socio-semantic communities by appraising the social, semantic and socio-semantic realms simultaneously; 
  • (ii)  drastically improving content analysis by replacing classical distributional approaches with clause analysis, thus enabling quantitative approaches rendering the linguistic complexity of utterances in web corpuses; 
  • (iii) fostering the interface between these methods and qualitative approaches, especially through a couple of broad case studies
  • (iv) developing interactive platforms implementing the above innovations and facilitating digital social research.
