Scientific Expertise and Media Discourse


Now more than ever, the ability of journalists to quickly contextualize information and find experts who can answer their questions is becoming a key asset in creating relevant and quality news stories. This project aims to leverage interviews of scientists by journalists, by developing a web platform that automatically maps the topics covered by Avis d’experts, RTS, Le Temps and Wikipedia, in order to help journalists to take position in the face of current events in general and misinformation in particular.

The platform, called CompaSciences, allows to explore and compare the content of the last 7 years from Avis d’experts, all the programs of RTS, the archives of Le Temps and Wikipedia. In addition, the Avis d’experts database allows the inclusion of scientific experts, thus offering a systematic mapping of their media appearances in the information ecosystem of French-speaking Switzerland.

A continuation of this project called “CompaSciences 2.0” was launched in March 2021 with renewed support from IMI.
