Thanks, John. It's little surprise to me that allowing for these 
reduced-relative constructions complicates parsing, for machines and 
humans alike.

I am, though, interested in seeing what research has been done in the 
NLP field with respect to these reduced-relative passives, such as how 
accurately parsers or other systems recognize them and correctly 
determine their voice.

Regards,
Sean
