It seems to be a very domain specific solution, they are trying to present versions of words in customer requested domain names if already taken.

Like you type in “stargazer. com”, system sees it’s already registered, and returns a “sorry sir it’s taken” page, with similar words listed as “but maybe try these words: astronomer, observatory, telescope, shooting star...”.

So it’s not serious translation, more of an inexpensive quick dictionary search. I guess it’s okay for its intended purposes.
