Currently...

• Features are "TODO", update.
• Is there a download link anywhere?

Emailed the authors to ask about it

I have emailed everyone on the author list. None of the emails went through except one, and that person just said something like "I am no longer in possession of it".

I'm not sure the ATIS corpus is still existing

Tried emailing the contact email at https://ml.rwth-aachen.de/

More emails later, even tried talking to the web team at RWTH.

Got one response, advising me "You might try Sarah Morrisey at Dublin." which I believe refers to http://imar.ie/zee_team/dr-sara-tucker-morrisey/

https://www.researchgate.net/profile/Sara-Morrissey

Was not able to find current contact info

Web Team told me to try https://www.informatik.rwth-aachen.de/cms/informatik/Forschung/Forschungsbereiche/Professuren-und-Dozierende/~mubg/Univ-Prof-Dr-Ing-Hermann-Ney/, emailed them as well

OK, let's just remove it for now.
