14. The computer-implemented method of claim 13 , wherein each selected second translation being selected based on an inverse number of routes linked to a given word in the second text corpus includes scoring translations higher for selection that have words linked to fewer semantic tags in the second text corpus as compared to other translations from a same list.
13. The computer-implemented method of claim 12 , wherein selecting, from each list, a second translation and adding the second translation to the second text corpus includes selecting the second translation from within a subset of translations of each list of translations, the subset determined based on the machine translation accuracy scores.
