My main area of research deals with the use of tabulation techniques in
Computational Linguistics and Logic Programming, relying on the
notions of Push-Down Automata and
Dynamic Programming. I wish to
show that many linguistic formalisms may benefit from well defined and
understood tabulation mechanisms, for instance in the case of Tree Adjoining Grammars (TAG), and, more
generally, of Midly Context Sensitive (MCS) formalisms using
Thread Automata. This work is completed by the development of
Since 2003, I became more and more interested by the notion of
Meta-Grammar that provides an abstract layer of syntactic
description based on hierachies of classes grouping elementary
constraints and providing/requiring resources. These classes may be
``compiled'' to get a grammar, in some target formalism, such as TAGs
or LFGs. This interest has led to the development of a MG compiler
MGCOMP and of FRMG, a French MG that
uses factorization operators provided by DyALog to produce a very
I am also interested in developing infrastructures to help natural
language processing (NLP). One way is to use nice representation
formats based on XML to encode linguistics resources (grammars,
meta-grammars, shared derivation forests, shared dependency forests,
morpho-syntactic annotations). In relation with this line of work, I
became involved in an international effort driven by ISO TC37 SC4 to
standardize linguistic resources.
I am also involved in information extraction and knowledge
acquisition applications, starting from parsing output. These
thematics include the exploration of error mining and correction
techniques and the processing of botanical corpora.
