Hi Barry,

Thanks,

it's a bit more work than I envisaged. You have to
1. implement word alignment, given the best hypothesis.
2. add the alignment to the mosesserver
For (1), there is code in
IOWrapper::OutputNBestList(
const Syntax::KBestExtractor::KBestVec &nBestList, long translationId)
to output the alignment in the n-best list. Alignment for best hypothesis
is very similar, even easier, but not the same.

For (2), just follow the phrase-based code in mosesserver

Thanks, Hieu. I will try and probably seek support from you later on.
