Different trees for the same constructions

There’ is an Expletive

Constructions like there is no man exercising or Er is geen man aan het sporten (from 3897p) get different analysis depending on what parser is used.

CCGbank-based analysis:

ccg(407,
 ba(s:dcl,
  t(np:thr, 'There', 'there', 'EX', 'I-NP', 'O'),
  fa(s:dcl\np:thr,
   t((s:dcl\np:thr)/np, 'is', 'be', 'VBZ', 'I-VP', 'O'),
   fa(np,
    t(np/n, 'no', 'no', 'DT', 'I-NP', 'O'),
    ba(n,
     t(n, 'man', 'man', 'NN', 'I-NP', 'O'),
     lx(n\n, s:ng\np,
      t(s:ng\np, 'exercising', 'exercise', 'VBG', 'I-VP', 'O'))))))).

Predicative PP

Predicative PPs are sentence modifiers rather than an argument of a copula like in CCG or other grammar formalisms.

[623] Een volwassene is in het amfitheater en praat met een jongen

✔️ Determiner takes a predicative adjective

This is also an unexpected analysis (and most probably wrong as I don't find such analyses in Alpino trees)

✔️ Solved by adding a fix rule
