Marseille

En résumé

I have a PhD degree in computer science with a focus in Semantic Web Technologies (RDF, ontologies, SPARQL, ...).
Currently I am a Post-doctoral Research Engineer at Protisvalor working on the IMARECULTURE project at LSIS Marseille.
I obtained my doctorate degree in December 2016 at the University of Montpellier/LIRMM Laboratory where I defended my thesis: "Profile-based recommendation methods are able to significantly reduce human effort in linking and modeling RDF data".

I am broadly interested in: semantic web, information retrieval, information extraction, text mining and data mining, deep learning.
