Argument and transparency
in public debate

We offer a web-based format of structured debate on topics such as land development, public policy or issues of science and society. Our debate platform is structured around a thematic graph.

Areas of engagement

Opportunities offered by the platform

  • —  Make comments and participate in debate
  • —  Present debate topics in the form
    of thematic graphs
  • —  Collectively analyze annotated comments
    and create syntheses

Technology & methods

Contribute to the debate

Our signature characteristic is data-visualisation in the form of a thematic graph presenting a comprehensive overview of discussion topics, enabling individual participation while navigating levels of increasing granularity. The platform enables commentary and discussion on questions prepared and documented in advance by the debate Organizer. This presupposes an initial intention and involves an element of preparation.

Reconstruction and dissemination

To ensure a clear connection between in-person and online debates, in-person events are reconstructed in a format that makes it possible to follow the discussion on the platform, thus broadening and diversifying the panel of participants. We employ rigorous data reconstruction protocols derived from our scientific collaborations, whether from collective note-taking, audio transcriptions, or approval by the speakers themselves before publication online.

Along the same lines, dissemination is designed to increase the diversity of viewpoints through targeted communication modes along with community management operations.

Analysis of contributions

In collaboration with Hervé Marchal, professor of sociology at the Georges Chevrier Center for Research in Societies, Sensibilities, and Care (LIR3S) at the University of Bourgogne, we have developed a method of annotation of verbatim notes and transcriptions. This consists in establishing an objective, stating a hypothesis, and defining a process of annotating contributions. Our technology enables analysis of a large text corpus in support of a transparent interpretation. The outcomes of debates are thus propelled and authenticated by maintaining links between the composite reproduction and that which was expressed in real time situations.

Regulations and security

  • —  CartoDÉBAT, thanks to its ongoing work with the Center for Functional and Evolutionary Ecology (CEFE) and National Center for Scientific Research (CNRS), aligns with the goals and consultation procedures for land development in the digital space, in the spirit of the law on Reconquest of Biodiversity, Nature and Landscapes (2016).
  • —  CartoDÉBAT is signatory to and applies the principles of the Charter of Public Participation put forth by the Ministry of Ecological Transition and Solidarity of the French Republic.
  • —  CartoDÉBAT adheres to the Data Protection Regulations of the European Union through a procedure of privacy-by-design. The rights of users of the platform are thus guaranteed as well as the security and traceability of data.

Critical thinking

Current forms of manipulation of discourse, notably fake news and trolls, influence our perceptions and create media echo chambers in social media settings, especially among youth. With our academic partners and support from the national development fund Caisse des Dépôts, the CartoDÉBAT team is engaging with this issue to create a digital platform for high school students that promotes critical thinking and the development of reasoning skills.

Benefits of using digital debate

Designers of software interfaces know very well that design and function influence behavior. CartoDÉBAT is designed to render an account of the challenges of debate and of diversity. The goal is to:

  • —  emphasize ideas and choices detached from personalities
  • —  develop a project over time
  • —  provide precise data categories to achieve evidence-based syntheses
  • —  retain the links between composite reconstructions and citizens' remarks in their context, maintaining confidence in the debate.
