I'm looking to reconcile about 40,000 corporate names against LCNAF to see whether they are authorized strings or not, but I'm drawing a blank about how to get it done.

I've used http://freeyourmetadata.org/ for reconciling subject headings before, but I can't get it to work for LCNAF. Has anyone had any experience in a project like this? I'd love to hear some ideas for automatically dealing with a large data set like this that we did not create and do not know how the names were created.

Thanks!
