Statistical dependency parsing of French

Université Paris Diderot - INRIA

Content : This page gathers various resources for the statistical dependency parsing of French. In particular, preprocessing code and learnt models/grammars for MaltParser, MSTParser, Berkeley Parser, and a constituent-to-dependencies conversion tool for French.

Many thanks to Joakim Nivre, Ryan McDonald and Slav Petrov for making their parsers available.

Funding : Part of this work is performed within the ANR SEQUOIA project (large coverage probabilistic syntactic parsing of French).

Dependency Corpus

The French Treebank consists in 12500 sentences of the Le Monde newspaper, annotated for morphology, phrase-structure and grammatical functions (Abeillé A. and Barrier N., Enriching a French Treebank, LREC'2004).

It has been automatically converted into surface dependency trees (cf. TALN'2009, LREC'2010), and here is a description of the resulting annotation scheme : French surface dependencies annotation scheme (in French).

We distribute the converted dependency treebank freely provided one has the licence for the original French Treebank (see here).

Once you have the licence, you may contact marie . candito @ linguist . univ-paris-diderot .fr for the dependency treebank.
