Connected objects, specifically conversational agents like Google Home, bring a new dimension to interaction and could become a mean of influencing individuals. They are currently neither regulated nor evaluated and very obscure. Based on the study of "nudges", techniques to modify the behavior of people, the team of Laurence Devillers "Affective and social dimensions in the spoken interactions" with Ioana Vasilescu, Gilles Adda of LIMSI - CNRS, and the "Digital Economy" team from the RITM laboratory; Grazia Cecere, Fabrice Le Guel and Serge Pajak, University Paris-Sud, have decided to collaborate to highlight the importance of ethics in the creation of these objects.

Julie Josse, professor of statistics at the École polytechnique and researcher at the French Centre for Applied Mathematics (CMAP), and Gaël Varoquaux, Parietal team researcher at the Inria Saclay - Île-de-France centre, have decided to combine their expertise in order to tackle, together, the problems of missing data and to propose new decision support methods. The MissingBigData project has been selected by the DATAIA Institute as part of its first call for research projects. How did this collaboration come about? What are the challenges of their interdisciplinary research? Julie and Gaël present MissingBigData.
