Building sustainable online engagement has become a major challenge for the media industry since it means competing against platforms that have been engineered to capture user attention. This project wants to add interactivity to traditional news articles. First by building an infrastructure that supports the creation of data-supported articles, in particular in the data collection, processing and visualization processes. Then by developing methods to automate the intervention of experts. To do this, scientists and engineers will rely on the platform of the “Media Observatory Initiative” which preceded this project. In the end, new formats will be explored with partner institutions, researchers and students. This research effort will lead to a series of data-supported articles and will pave the way for future data-journalism projects.
