This presents a challenge to SMT, both for the word alignment subtask as well as reordering. By breaking up Turkish and English words into morphemic subcomponents and doing some further filtering for "appropriateness" of morphemic agglutination with predicted root forms, the authors are able to get a small gain in BLEU (1.5-2 points). However, the baseline score is quite low (~7.5 BLEU), and even the prediction of root forms is poor. Is the problem lack of data? (only 20K training examples). The authors suggest that there is a also a significant amount of reordering that messes with the word alignment process.}
