I am aware only of ATIS3, which reportedly has at one time or another
had SQL and/or slot-and-filler representations provided for the
sentences. I am also aware that the LDC offers some form of ATIS3, but
there are hints that the representations offered there are the ordinary
sort of parse trees rather than indications of meaning. The description
in the LDC Web pages does not give any hint as to the sort of markup
provided, and it further indicates that whatever the markup is is far
from complete.
If anyone could elaborate on what the LDC provides for ATIS3, or direct
me to other sources for corpora with semantic representations, I will
appreciate it.
