Hi Martin, I’m afraid that I don’t remember. It seems plausible, though. You might try generating a noun from its sigma projection as a simple test.

Parsing works as expected, and so does regeneration as long as I don’t add or remove features. However, my ultimate goal is to generate from s-structures, so I’ve manually reduced some files resulting from parsing to just the respective s-structures and tried generating from those. Even though I’ve made all f-structure features addable, generation fails. (And so does regeneration when I make that same list of features removable and addable.) Am I trying something that the generator isn’t made for (yet)? Thanks, Martin On October 1, Nuance Automotive will become Cerence Inc. – A.I. for a world in motion.
