After months of discussions, calls, commits and proofs of concept, is finally out !

With this website, we celebrate the real public birth of a project we have been questioning since the terrorist attacks in Paris in 2015.

Through exchanges with people from many different horizons, we were able to formalize our ideas and to summarize it all in this place. We'll try to keep it up to date as the project goes on.

Application to PSES-HSF 2016

By the end of June and the beginning of July, the 2016 edition of Pas Sage En Seine will be held jointly with the HackerSpaces Festival in Choisy-le-Roi, France.

We decided to apply for a conference slot during the event. We deeply think this project is in the very scope of this hackers' gathering : we aim for a better understanding of social evolution through technology.

Please find hereinafter the project summary and description provided in the filled application :

Summary for schedule leaflet

Alors que les réseaux sociaux prennent une place toujours plus importante dans la société, l'analyse des réactions qui y sont postées permet une compréhension de la dynamique sociale.

Le projet, c'est un ensemble d'outils semi-automatisés pour extraire et analyser le sens du flux continu produit par nos sociétés connectées.

For non-french readers :

As social networks are taking a more and more important spot in our societies, the analysis of reactions posted online paves the way for a better understanding of social dynamics.

The project is a set of semi-automated tools to extract and analysis the hidden meaning from the continuous flow generated by our connected societies.


Les réseaux sociaux permettent aujourd'hui à chacun de réagir publiquement, à chaud, à une actualité.

Avoir accès aux états d'esprit à un instant donné ouvre la voie à l'analyse de la dynamique sociale suite à un évènement majeur telles que les attaques de Paris.

Les échanges en ligne intéressent la sociologie, comme en témoignent des recherches récentes (quota_atypique et d'autres) ; nous nous proposons de mettre en œuvre des analyses semi-automatisée (quantitatives & statistiques, qualitatives, classifications, etc.).

Par ailleurs, la présence en ligne d'acteurs médiatiques (médias traditionnels & classe politique) permet d'étudier la relation de causalité entre annonce publique et réaction de la population. Au delà de son aspect technique, ce projet questionne ainsi le rapport entre réseaux sociaux et vie en société, revêtant une dimension citoyenne supplémentaire.

Here again, the english translation :

Social networks offer today a way for everyone to publicly and spontaneously react to an incoming news item.

Having such a instantaneous access to states of mind on a population-scale allows for a in-depth analysis of social dynamics after a major event, as an example, we chose the 2015 Paris terrorist attacks.

Online communications are interesting to sociology and are actually subject of recent research projects (quota_atypique and others) ; we aim at setting up semi-automated analysis (quantitative & statistical, qualitative, classifications, etc.).

More over, the online presence of media entities (traditional medias & politicians) gives the possibility to study the causality between a public announcement and people's reactions. Beyond its technical aspect, this project questions the link between social networks and societal life with a civic dimension.
