Dear developers,<br>
<br>
I'm wrapping up this year's iteration of Ling 567 and have come to a question<br>
about transfer rules. One of our sentences is "Cats chase dogs and sleep".<br>
One of our languages is a VSO language, which doesn't have VP coordination.<br>
It does have subject drop, so the authors of this grammar have translated that<br>
sentence as "Tigers (!) chase dogs and [something] sleeps". We wanted to<br>
see if we could write a transfer rule that would take the VP coordination MRS<br>
from English and make the corresponding S coordination (with subject drop),<br>
worrying only about the case where the second conjunct is an intransitive verb.<br>
<br>
We got as far as:<br>
<br>
vp-coord-to-s-coord := monotonic_omtr &<br>
[ CONTEXT [ RELS <! [ PRED "_and_coord_rel",<br>
L-INDEX #e1,<br>
R-INDEX #arg0 ],<br>
[ ARG0 #e1,<br>
ARG1 #arg1 ] !> ],<br>
INPUT [ RELS <! [ PRED #pred,<br>
LBL #lbl,<br>
ARG0 #arg0,<br>
ARG1 #arg1 ] !> ],<br>
OUTPUT [ RELS <! [ PRED #pred,<br>
LBL #lbl,<br>
ARG0 #arg0,<br>
ARG1 x ] !> ],<br>
FLAGS.SUBSUME < #arg1 > ].<br>
<br>
... which does apply and doesn't spin. However, the coref tag #pred between INPUT<br>
and OUTPUT don't seem to be doing any work. That is, the ARG0 is getting<br>
copied across (the identity between the _and_coord's R-INDEX and the 'new'<br>
EP's ARG0 is there) but the PRED value is getting lost.<br>
<br>
Does the LOGON transfer formalism allow for preserving PRED values? If so,<br>
what is the syntax I should be using?<br>
<br>
Many thanks,<br>
Emily<br>
