LittlePrince — the Stanza legacy: EWT customs before 2.11–2.17 alongside new ones

Gist. The annotation grew out of the output of Stanza trained on older EWT versions. The students corrected mainly trees and UPOS. So FEATS, lemmas and some labels keep the old norm, while what was corrected is already new. The 2017-era treebank mixes two norms:

• :tmod/:npmod alongside :unmarked: obl:unmarked 19, obl:tmod 6, obl:npmod 3. Even day occurs both as obl:unmarked (5) and as obl:tmod (2).
• Agreement by form only: 317 of 625 finite verbs with Tense lack Number/Person. Past with Number — 151, mostly was/were (76), but also say 6, do 5, have 4: the students filled in some.
• Possessive lemmas by the old rule: his → he (39 versus 5 his → his), your → you (14 versus 2), their → they (3), our → we (2), mine → mine.
• Case=Gen on possessives — only 12 of 122 in nmod:poss (tb.en.poss-gen 110 of 122).
• Expletive there without PronType=Dem — 15 of 15. EWT since 2.17 — Dem.
• not without Polarity=Neg — 65 of 69. EWT since 2.15 — everywhere.
• NumForm in MISC, not in FEATS: tb.en.num-feats 142 of 142.
• Subordinate when/how as SCONJ mark: 18 of 43. EWT since 2.11 — ADV advmod.
• you with Number — 11 of 85: traces of the GUM custom that Stanza was also trained on (GUM — you has Number=Sing or Plur, and the verb agrees with it).

Conditions and exceptions. advcl:relcl (6), nsubj:outer (2), obl:agent (6), ExtPos (22) are already in the treebank: newer customs appear where the students corrected the tree.

Examples.

• lpp_1943.284 " One day , " you said to me… — day: obl:tmod.
• lpp_1943.228 …there were on the planet… — there: expl without PronType=Dem.
• lpp_1943.265 …the secrets of your sad little life… — your: lemma you, without Case=Gen.
• lpp_1943.267 …on the morning of the fourth day , when you said to me… — when: SCONJ mark.
