Filters all terms that don't have the specified French Treebank tags assigned. The terms are filtered out of the bag of words and the documents as well if deep preprocessing is checked.
A term is kept if at least one of the specified French Treebank tags is assigned. If strict filtering is set, all specified French Treebank tags have to be assigned to a term. See http://www.llf.cnrs.fr/Gens/Abeille/French-Treebank-fr.php for details about French Treebank.
