[ParSem] semantic roles for LFG grammar engineering

[Emily M. Bender]

Dear Adam,

I looked into this some for my recent book, and from what I could find, no
one has ever produced a fully comprehensive set of semantic roles (see Ch
8, thing #68).  I'm not familiar with Sowa's system, but I think what's
going on in VerbNet is that role names are re-used across predicates but
not meant to carry the same content in those different uses.
