Thierry Poibeau

Director of research
CNRS, Laboratory adjunct head


I am a CNRS Director of Research and adjunct head of the LATTICE laboratory (Langues, Textes, Traitements informatiques et Cognition). I currently hold a PrAIRIe fellowship (PrAIRIe = Paris Artificial Intelligence Research Institute) in Natural language Processing and Digital Humanities. I am also an Affiliated Lecturer at the Department of Theoretical and Applied Linguistics (DTAL) of the University of Cambridge, and part of Cambridge Digital Humanities.

In 2018-2019, I was a Rutherford Visiting fellow at the Turing Institute (London / Cambridge). From 2003 to 2009, I worked as a CNRS Research Fellow at Laboratoire d’Informatique de Paris-Nord. In 2002-2003, I was an associate professor at the Centre de Recherche en Ingénierie Multilingue (CRIM) within the Institut National des Langues et Civilisations Orientales (INaLCO) and before that a research engineer at Thales Recherche et Technologie (1998-2002).

I mainly work on Natural Language Processing (NLP), especially on the following topics: Information Extraction, Question Answering, Semantic Zoning, Knowledge Acquisition from text and Named Entity tagging. Apart from NLP, my main interests include Language Acquisition, Cognitive Science, Epistemology and the History of Linguistics.

More recently I have been active in two other domains of research.

Digital Humanities is a growing field at the intersection of computational methods and the Humanities. I have recently developed a wide range of activities around this theme at LATTICE and we now have a number of running projects (esp. Oupoco and the French part of BookNLP), see here and here for recent publications. I am also involved in the PSL Master in Digital Humanities.

Last but not least, I am especially interested in language diversity and language typology. I work on Finnic (i.e. Finnish and closely related languages) and more generally Uralic languages. We have recently developed multilingual parsing models that have been applied successfully to under-resouced languages like Finnish, Saami and Komi (joint work with KyungTae Lim and Niko Partanen). See here for more information.


Recent Publications (books)

Most of my publications are referenced in the open repository HAL, with a PDF version for open source documents. A comprehensive list of references until 2017 is available here.

In 2017, I have published a survey on machine translation (Machine Translation, MIT Press – Essentiel knowledge).

The dream of a universal translation device goes back many decades, long before Douglas Adams’s fictional Babel fish provided this service in The Hitchhiker’s Guide to the Galaxy. Since the advent of computers, research has focused on the design of digital machine translation tools—computer programs capable of automatically translating a text from a source language to a target language. This has become one of the most fundamental tasks of artificial intelligence. This volume in the MIT Press Essential Knowledge series offers a concise, nontechnical overview of the development of machine translation, including the different approaches, evaluation issues, and market potential. The main approaches are presented from a largely historical perspective and in an intuitive manner, allowing the reader to understand the main principles without knowing the mathematical details.

This book has been translated in several languages, especially in French by Odile Jacob (Paris, May 2019). The French version has been completely updated to take into account the last developments in neural machine translation.

Other versions of the book exists in Chinese, Korean

Teaching and lecturing

I am regularly lecturing in various institutions

I am especially involved in the Master in Digital Humanities of Paris Sciences et Lettres (with the Ecole des chartes and the Ecole pratique des hautes études). I am the ENS representative in this programme.

I am also involved in two ‘intensive PSL weeks’ on ‘Ethics and AI’ for the first one, and on ‘Digital Humanities and AI’ (DHAI) for the second one, held each year, in Spring  (DHAI) and Autumn (Ethics and AI).

Research projects

    • I hold a PRAIRIE chair (PRAIRIE si the 3IA Institute of Paris). Within PRAIRIE, I mainly work  on natural language processing and digital humanities, as well as on the practical impact of AI on society.
    • I am also involved in the MEDIALEX project (with Médialab/SciencesPo Paris, CREST and INA). In this project, we explore the relationships between the media and the political sphere. The project is led by Sylvain Parasie, from SciencesPo.
