| # Enhanced UD for French UD treebanks | |
| Graph-rewriting rules have been applied to UD_French_Sequoia, UD_French_FQB, UD_Frenc_FTB and UD_French_GSD (UD 2.5) | |
| to produce enhanced UD treebanks for French. | |
| The handled phenomena are described in (Candito et al., DEPLING 2017): | |
| - subjects of infinitive verbs (for more cases than simple control and raising, see Candito et al. DEPLING 2017) | |
| - neutralization of diathesis alternation | |
| - distribution of coordinated dependents: | |
| -- coordinated subjects, obj, obliques, iobj; xcomp | |
| -- coordinated modifiers of nouns | |
| - distribution of coordinated heads: | |
| -- distribution of subject of coordinated verbs | |
| -- distribution of complement of coordinated verbs (if attached to first conjunct, and posterior to last conjunct) | |
| -- distribution of modifier of coordinated nouns (same constraint) | |
| The originality of the obtained enhanced graphs is the neutralization of diathesis alternation. | |
| Labels of the form xxx@yyy (for instance "nsubj:pass@obj") mean that the observed function is xxx, but the deep (canonical) function is yyy. | |
| Hence, in order to fully benefit from the neutralization of diathesis alternation, one can keep the canonical functions only, | |
| namely the yyy part of the labels xxx@yyy. | |
