UD conversion errors

[amir-zeldes]

UD conversion error list, examples added as comments:

• [x] Subject relative nsubj with 'which' becomes 'obj' (turns out to be related to xcomp rule)
• [x] Subject nsubj -> obj in copula environment (same issue as the above)
• [x] Adverbial copula predicates should be treated like PP predicates (currently 'be' is left as the root in "it is here" but not in "it is in the house", see real example below)
• [x] Consider adding a rule: "and" with func dep -> reparandum (only occurs once)
• [x] Bug affecting coordinated prepositions (conj still comes out of the prep -> case; should come from lexical item)
• [x] Handle PP root with modifiers

Another example of coordination of prep:

1 The DT 2 det 2 purpose NN 0 root 3 of IN 2 prep 4 the DT 5 det 5 author NN 3 pobj 6 and CC 3 cc 7 of IN 3 conj 8 the DT 9 det 9 translator NN 7 pobj 10 : : 0 punct

by Logan: based on fixed in original SD dep

prep + pcomp seems wrong here. I think 'based on' should be SD vmod + prep, which would solve the problem (alternatively it's prep + mwe, but I think we can literally see this as a verb).

[amir-zeldes]

Example of PP root with modifiers:

1   Is  _   VBZ _   _   4   cop _   _
2   it  _   PP  _   _   4   nsubj   _   _
3   always  _   RB  _   _   4   advmod  _   _
4   about   _   IN  _   _   0   root    _   _
5   them    _   PP  _   _   4   pobj    _   _
6   ?   _   SENT    _   _   0   punct   _   _

... Actually this is an SD error, never mind. Correct SD with guideline on prep predicate taking 'be' as root should be:

1   Is  _   VBZ _   _   0   root    _   _
2   it  _   PP  _   _   1   nsubj   _   _
3   always  _   RB  _   _   1   advmod  _   _
4   about   _   IN  _   _   1   prep    _   _
5   them    _   PP  _   _   4   pobj    _   _
6   ?   _   SENT    _   _   0   punct   _   _

This converts fine.
