Sentences with an empty parse tree

[jonathon-read]

I'd just like to share that we've noticed a few sentences in the data have empty parse trees (i.e. parsetree: "(())". Some of the sentences do look hard to parse, but here is the list, in case you think there's some issue present:

The parser choked on these for some reason. I was thinking about patching them outside of the script. But that will make it less reproducible... So we leave it out to the participants to reparse those as necessary.

Hi @attapol, do you still have the settings for the Berkeley Parser used for the English task? I am working on the ST data, and would like to get as close as possible the missing parses to the rest of the parses provided. Thanks!
