Using HPSG-Neural-Parser for parsing raw sentence

[disooqi]

Hello, I am trying to use your work to parse a raw sentence, but I can't find any sample input files showing the format of the sentence. Should I use conll-U format for the input file and/or what linguistic information do I need to provide i.e. lemma, POS, MWT, ...

I have been working on this issue for few days now and I have tried to pass to parse.sh a raw sentence in a single line, empty dependency tree with POS, and conll-U format but without success.

When I pass the following raw sentence:
Which German cities have more than 250000 inhabitants?
I get the following parse tree:
(SBARQ (WHNP (UNK Which) (UNK German) (UNK cities)) (VP (UNK have) (NP (UNK more) (UNK than) (UNK 250000))) (UNK inhabitants?))

Thanks
