I think you misunderstood the https://wiki.openstreetmap.org/wiki/Name_finder:Abbreviations page. It should list common abbreviation that a lot of places share. I think abbreviations like "Federation of Indian Chambers of Commerce and Industry" or "New Okhla Industrial Development Area" exist only for one place.
Ah, I see, thanks for letting me know. So where do abbreviations like that go?

You can use the short_name tag, for example University College London

Thanks! I've started doing that in my tagging ^^

I've reverted the page - correctly, I hope (I don't edit wikis very often) :)
