Hi Irene
You can't use bleu on a single sentence. Since it's normally a product
of 1,2, 3 and 4-gram precisions, it will be 0 if there's no 4-gram
matches. Try evaluating on a larger set, say several 100 or 1000 sentences,

Hi, Philipp
Thanks for the "compliments".
I just created two dummy files contains exactly the same English
sentence. I just randomly copied some of the data from internet to the
file.'
The command I use is
~/mosesdecoder/scripts/generic/multi-bleu.perl -lc true file < translated file
Thank you

Hi,
BLEU scores of 0 are extremely hard to get, so you should be proud.
More seriously: can you send the files that you tested on and how
you ran the command?
