i believe we did that for the SDP collection earlier this year (for
which there also was an announcement paper at LREC), and we do in fact
see the occasional download and even a couple of reports from people
using one form or another of the semantic graphs.

dan and i have talked about making another announcement once WikiWoods
1214 complements the Ninth Growth; i hope that will be available for
download before the summer.  though, frankly, i fear there is even
less of consumer base for HPSG derivations and our spindly-looking
phrase structure trees than there is for the ERSs.
