We run GIZA + + ( Och and Ney , 2000 ) on the training corpus in both directions ( Koehn et al. , 2003 ) to obtain the word alignment for each sentence pair .
improved statistical alignment models
Franz Josef Och Hermann Ney
The development set is NIST02 evaluation data , and the test datasets are NIST05 , NIST06 , and NIST08 . We run GIZA + + ( Och and Ney , 2000 ) on the training corpus in both directions ( Koehn et al. , 2003 ) to obtain the word alignment for each sentence pair . We train a 4-gram language model on the Xinhua portion of the English Gigaword corpus using the SRILM Toolkits ( Stolcke , 2002 ) with modified Kneser-Ney smoothing ( Chen and Goodman , 1998 ) .
