I am sure that your tool can extract some
content, with some degree of accuracy, from some
kinds of texts. I am also sure that it cannot
extract all the content with full accuracy from
arbitrary free text. Exactly what it is capable
of can only be determined by experiment,
preferably conducted in an open peer-reviewed
scientific setting. Do you have any empirical
results to report? (02)

What kinds of inference can your formal ontology
support? What logic is it written in? (04)

If it did what you seem to be claiming it can do,
it would be an AI miracle. I however do not
believe in miracles of any stripe. The history of
AI is littered with somewhat overinflated claims.
While recent work has produced impressive gains
in performance, the world is still a long way
from having a fully competent free text
comprehension system. I realize that commercial
pressure may require you to focus on the positive
side of things, but IMO we should all guard
against overinflated claims, which tend to
produce backlash. (06)
BTW, I would be delighted to be proved wrong; but
I have high standards of proof. (07)
