i3 seminar “Analysis of online participation” will welcome

Mathieu Brugidou and Philippe Suignard


What can word embedding algorithms do

for the sociological analysis of texts?

Mathieu Brugidou is a senior researcher at EDF R&D, Energy Technology and Society Research Group, and a research associate at the Pacte laboratory (UMR 5194), CNRS-Université Grenoble Alpes- Sciences Po Grenoble.

Philippe Suignard is an Engineer and Research Expert at the ICAME Department (Business Innovation, Market and Environmental Analysis), EDF R&D.

Abstract: In this presentation, we propose to further the evaluation of the contribution of so-called “word embedding” algorithms to the sociological analysis of texts: on the one hand, by confronting the results of the semantic analyses of these algorithms to the now well-known approaches of textual data analysis or textometry; on the other hand, by focusing on what is one of the main obstacles to the sociological analysis of the web: the difficulty to characterize sociologically the authors of statements from the web. To this end, we analyze statements from “civic tech” platforms – i.e. the “Grand Débat National” [Great National Debate], a governmental platform, and its political and algorithmic riposte provided by a collective of Gilets jaunes, the “Vrai Débat” [The Real Debate]. A third corpus from the “Entendre la France” [Hearing France] platform, with the same design as the “Grand Débat National” and documented in terms of socio-political properties, allows us to characterize the speakers according to their discourses and to attempt to predict, through machine learning approaches, “pseudo-properties” assigned to the contributors of the “Grand Débat National”.


i3 seminar “Analysis of online participation”

The “Analysis of Online Participation” (APeL) seminar aims to develop reflection on approaches to the use of data about the online usage and participation. The seminar is a place for researchers from various backgrounds to meet and exchange knowledge, practices and know-how. At each session, the seminar guests present and discuss the “making of” of one of their researches: construction of the survey, specificities of the data engineering implemented, tools for capturing / building corpora, analysis strategies and tools used, etc.

Information and registration

The seminar is open to all. Please register here to participate in this session.
