Dear Saeed,
according to the first sentences of your email I understand that
you want the phrase-pairs that are used for producing the
translation of the given sentence, as well as their alignments.
But, according to the sentence that you say "The output of
the decoder is not exactly same as the target sentence (which
seems problematic for you)" I guess that you are
looking for the best phrase alignment of the given sentence-pair,
regardless of what Moses uses for producing the translation of the
given sentence.
May I ask you to describe it more clearly?
Bests,
Amin

Dear all,
I have a question about finding the best phrase
alignments. The alignments are used by MOSES during the
decoding phrase.
I have a pair parallel sentences ( a source / a target).
I need the best phrase alignment between the source and
target sentences. The best phrase alignment is
a alignment that MOSES is used to translate the source
sentence to the target sentence.
Let me use an example to explain what i want.
Example:
I have a pair sentence:
Source : I go to the home
Target : man be khaneh miravam (in farsi)
I need the following alignment:
The Best alignment : [I-->man] [to the --> beh]
[home-->khaneh] [ go --> miravam]
the result includes two sort of information
1- the best segments
2- the best alignment
We can use MOSES for extracting the alignments when
using training sentences as input sentence of the MOses's
decoder. But there is problem. The output of the decoder
is not exactly same as the target sentence.
I know that the giza++ is used for
word alignments. I need a solution for phrase alignments.
Tnx
