Feature/UPOS combinations that should be ruled out across English treebanks

[nschneid]

We should tighten up the allowed combinations in the validator settings. Several that stand out as problematic but will require data fixes:

• Case=Nom in LinES: Case=Nom is applied widely beyond pronouns UD_English-LinES#17
• Degree for non-ADJ/ADV e.g. this query (first identified in Feature documentation tools/data/feats.json docs#1055) (GUM*, LiNES, PUD: fixed)
• Gender for non-PRON words in ParTUT: Gender feature applied too widely UD_English-ParTUT#2
• Number e.g. this query: Spurious Number feature on ADJs UD_English-ParTUT#3
• PronType for NUM, SCONJ e.g. this query (GUM*, LinES, PUD: fixed)

(Manually fixed some Definite, Tense, VerbForm issues in LinES and PUD)

Fixed the GUM PronType and Degree issues upstream, thanks

[nschneid]

In the validator I've disabled PronType for NUM/SCONJ, and limited Case=Nom to PRON. I think all the corpora are up to date with these changes (GUM changes are upstream).

The validator for English does not allow the negative twopart conjunction neither - nor to be annotated as Negative, neither by PronType nor by Polarity as these features are disallowed for upos CCONJ. What is the reasoning behind that decision?

[nschneid]

It's a good question—I don't know if it has been discussed. https://universaldependencies.org/en/feat/Polarity.html doesn't mention CCONJ one way or the other, and I don't see it on the universal documentation pages either. A CCONJ is a function word, but is it "pronoun-like"?

[nschneid]

Opened an issue for wider discussion: UniversalDependencies/docs#1056

[nschneid]

Degree is now limited to ADJ and ADV.

[nschneid]

AFAICT the only remaining issues now are Gender and Number in ParTUT.

[nschneid]

Validator configuration now updated for all these features. There is a pending decision about negative CCONJ (UniversalDependencies/docs#1056). Beyond that, LinES still has some validation issues. Can't tell for sure about GUM* because changes are upstream.

[amir-zeldes]

OK, I pushed a preview version to UD dev (just GUM, no reddit/GENTLE) so you can take a look, I think everything we discussed is implemented.

[nschneid]

Still some errors for GENTLE: http://quest.ms.mff.cuni.cz/udvalidator/cgi-bin/unidep/validation-report.pl?UD_English-GENTLE
