Jean-Philippe Prost

In short

Jean-Philippe is a Senior Lecturer (Maître de Conférences) in Computing at Aix-Marseille Université (AMU), where he teaches at the Technology Institute (IUT), and does his research at Laboratoire Parole et Langage (LPL) since 2018. Prior to this he was a Senior Lecturer at Université de Montpellier (2010 - 2018, IUT and LIRMM), a post-doctoral researcher at Université d'Orléans (2008 - 2010, LIFO), and a Natural Language Processing Specialist at numéro (Smart Analytics Ltd.) (2008, Manchester, UK).

He was awarded his Cotutelle PhD in Computer Science in 2008, by Macquarie University and Université de Provence. His work was supervised by Diego Mollá and Mark Dras at Macquarie, and Philippe Blache at Provence.

Prior to being an academic, Jean-Philippe worked as a Research Programmer (2001 - 2003, Macquarie University, Sydney), as a COOL:Gen Consultant (2001, IPP Consultancy Services, Sydney), as a Software Engineer (1998 - 2001, Sopra, France), as a Research Programmer and a Math teacher (1997, CNRS and Institut Leschi, Marseille, France).

His field of interest is Natural Language Processing (NLP). His work is concerned with Natural Language Understanding (NLU), the computational modelling of the graded nature of grammaticality (i.e. gradience), Model-Theoretic Syntax, and the use of constraints and constraint satisfaction mechanisms for NLP. More recently, he has been focusing on Knowledge Graphs and their use in NLP applications.
