Reasonable folks might inquire what the Association for Computational Linguistics does. Apparently, the Association does not Spell correctly nor even use spell check because their web sit includes the sentence "To date, there are 26 members of teh ACL that have been honored by the ACL as Fellows." (Colour red added to highlight most egregious misspelling.)
"Computational linguistics is the scientific study of language from a computational perspective." the web site states. (Italics in original.) Still doesn't mean a whole lot to me. Those of you seeking greater explanation can go to the Association web site linked above.
