Dear XLE-ists,
We are using XLE in a bilingual text generation project
(http://web.science.mq.edu.au/~ayeye), and we would like to be able to
generate sentences from s-structures rather than f-structures. It
seems that projections other than c- and f-structures get encoded in
the exported prolog files as attributes of the f-structure. This means
that generating from an s-structure technically boils down to
generating from an underspecified f-structure (where everything is
missing except the "s::" attributes). But even when declaring all
attributes of f-structures addable, we still cannot generate from
s-structures. I think this is because the PRED attribute cannot be
added to an underspecified f-structure, due of its central role in
ensuring completeness and coherence. Is there a way to work around
this limitation, short of using transfer rules? Has anyone ever tried
to generate from other projections than the f-structure? Any help
would be much appreciated.
Kind regards,
