The corpus UD_French-FQB is an automatic conversion of the French QuestionBank v1, a corpus entirely made of questions.


The original French QuestionBank is described in Hard Time Parsing Questions: Building a QuestionBank for French.. It was converted to UD with the conversion system described in the chapter 3 of the book Application of Graph Rewriting to Natural Language Processing and available on Inria Gitlab.

The original annotation scheme versions (phrase-structure, surface dependencies following the FTB scheme, Deep syntax annotations following the Deep Sequoia scheme are available at the following URL.

Recommended splits

Due to the UD constraints on the test set size (at least 10k tokens), we recommend to simply concatenate this treebank to the Sequoia and FTB treebanks in order to get a robust, less domain sensitive, parser. Those 3 treebanks are perfectly compatible and were converted by the same team.

In our own experiments, we either used the UD_French-FQB in a 10-folds cross-validation scenario or in a train/dev/test scenario with the i_th sentence in train, i_th+1 in dev, i_th+2 in test.
