Koehn and Hoang ( 2007 ) showed that the use of a POS factor only results in negligible BLEU improvements , but we need access to the POS in our inflection prediction models .

2We use an additional target factor to obtain the coarse POS for each stem , applying a 7-gram POS model . Koehn and Hoang ( 2007 ) showed that the use of a POS factor only results in negligible BLEU improvements , but we need access to the POS in our inflection prediction models . step through subject-verb agreement .
