Other versions (i.e. newer ones) should work as well. We currently require
SWI-Prolog 5.6.57 or higher for the ACE parser. The OWL verbalizer should
also work with slightly older versions.

I'm trying to release the next version of ACE View soon. In this version
you don't even have to specify the location of the SWI-Prolog executable because
libjpl knows it anyway.

There shouldn't be any difference between verbalizing small and large
ontologies.
There is a difference though between verbalizing simple and complex axioms.
For certain simple axioms (e.g. subclass axioms with named classes),
the OWL verbalizer webservice is not called at all, i.e. verbalization
is done in Java.

This URL would work if you had a mapping in your webservice configuration file,
mapping it to http://localhost:5123/. Do you have such a mapping?
If not, then just use http://localhost:5123/.
