[pet] MRS from ungrammatical input

[David Vaughn]

(sorry if this is duplicate!  I'm not sure if it went through the first
time... I hadn't joined the listserv yet...)

Hello,

Should PET be able to produce MRS output from *slightly* ungrammatical
input?  I'm not sure if this is theoretically possible to do from the PCFG
parse tree.  However, from looking at the C++ code, there seems to be some
functionality for this that has been commented out , e.g.

   //instantiate_robust(...)
   //unify_robust(...)
   //#include dag-robust.h

I've been trying to get PET to output MRS for the sentence "The boys wins."
Is this possible?  I can get the full PCFG parse tree, and I can even get it
to output a bunch of MRS fragments (opt_partial), but I'm looking for
something more complete to go with the complete parse tree.  btw, I'm not
using any of the ecl stuff, just the C++ MRS code.  Also, I'm using ERG
1004.

Thanks!
