i just had this problem too but using mteval-v12 didn't seem to help.

I ended up using the multibleu.pl script to do the evaluation. The sgml
stuff in mteval is pointless, complicated junk, imo.

Hi everyone
I'm following the moses manual and at the end of the verbose section in the
phrase-based tutorial, it is mentioned that "at the end, the best scoring
final
hypothesis is found and the hypothesis graph traversed backwards to
retrieve the best translation". My question is: is there an option in the
decoder that gives the best path followed in the translation graph to
arrive to the best translation?? and if yes what is it?? please it'll help
me very much if i have an answer.

Thanks in advance.

I'm assuming your second translation model is functioning as simple
dictionary with entries that only match source and target terms. While
only words or short terms can be is useful, it is better to have them in
contextual use within broader phrases or sentences.

Furthermore, the translation model is not the only influence selecting a
translation. So, are the OOV reports from the translation model or
language model? Your language model must also cover the target
vocabulary. Again, ideally the terms should be in broader phrases or
sentences.
