I am a Ph.D. student at the RIADI research laboratory in the National School of Computer Sciences (ENSI), University of Manouba in Tunisia. I am a teacher of computer sciences at Higher Institute of Multimedia Arts of Manouba (ISAMM). I obtained an engineering diploma from ENSI in 2009 and I had the master degree on Computer Sciences in 2010. My master dissertation focused on developing a new approach for analysing social networks data, stored in graph databases, using BI tools. My thesis research focuses on Information Retrieval, Arabic NLP, Morphological Analysis and Morphological Disambiguation with possibility theory.
