One of our sentences is "Cats chase dogs and sleep".<br></div>One of our languages is a VSO language, which doesn't have VP coordination.<br></div>It does have subject drop, so the authors of this grammar have translated that<br></div>sentence as "Tigers (!) chase dogs and [something] sleeps". We wanted to<br></div>see if we could write a transfer rule that would take the VP coordination MRS<br></div>from English and make the corresponding S coordination (with subject drop), <br></div>worrying only about the case where the second conjunct is an intransitive verb.<br><br></div>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></div>... which does apply and doesn't spin. However, the coref tag #pred between INPUT<br></div>and OUTPUT don't seem to be doing any work. That is, the ARG0 is getting<br></div>copied across (the identity between the _and_coord's R-INDEX and the 'new'<br></div>EP's ARG0 is there) but the PRED value is getting lost. <br><br></div>Does the LOGON transfer formalism allow for preserving PRED values? If so,<br></div>what is the syntax I should be using?<br><br></div>Many thanks,<br></div>Emily<br><br><div><div><div><div><div><div><div><div><div><br><br clear="all"><div><div><div><div><div><div><div><div><div><div><div><br>-- <br><div class="gmail_signature"><div dir="ltr">Emily M.
