UD scale: *manual native* — annotated by hand directly in UD; *converted from manual* — converted from manual annotation in another scheme; *converted with corrections* — converted and partly corrected by hand; *automatic with corrections* — automatic, with partial manual corrections; *automatic* — automatic; *not available* — the layer is absent.

## Size

| Split | Sentences | Tokens | Words | Multiword tokens | Empty nodes |
| --- | --- | --- | --- | --- | --- |
| train | 1 334 | 18 093 | 18 259 | 166 | 0 |
| test | 939 | 10 775 | 10 964 | 189 | 0 |

Tokens are surface tokens (Spanish `vámonos` is one), words are syntactic words (`vamos` + `nos`); multiword tokens are those split into several words; empty nodes are the `N.M` nodes of the enhanced graph. Splits dev are absent from the release.
