Welcome!

I'm French. I like B-trees and woody trees. Here is my resumé.

New: opening demo accounts for Piweb. Please contact me if you want an account to access one of Piweb's apps. More information in this blog post.

Mediation

I am currently doing scientific and digital mediation for the Médiathèque des Jardins de la Culture at Riom. For instance, I manage and maintain the blog de l'Atelier.

Development

Research

Spring – Summer 2019. For an internship at the Max-Planck Institute for Informatics in Saarbrücken, Germany, I worked under the supervision of Simon Raznewski and Gerhard Weikum on commensense knowledge bases. This resulted in DICE, a framework for extracting and consolidating additional facets about the facts in a knowledge base. The source code is available on GitHub. A web demo is also available.
