hi greg
printing word alignment is still a feature. In fact it's been cleaned
up, optimized, debugged, and now on by default. It works for both pb,
and hiero/syntax models.
The 2 arguments are
-print-alignment-info-in-n-best [0 or 1]
and
-alignment-output-file [file]
The arg ( -print-alignment-info) was removed it was redundant.
If you intend to use it, double check that your phrase table contains it.
Also, double check that your binary phrase table contains word
alignment. In the phrase-based case, there should be files called
*.wa

Hi Hieu,
I was wondering if I could ask a question about the flags in Moses
used for getting word-to-word alignments out along with the
translation. With the pre-November versions, we were using the
"-use-alignment-info" and "-print-alignment-info" flags to get word
alignments as an extra column in the output, like this:
We are selling a hard drive .
我们 的 销售 硬盘 驱动 器 。 ||| 0-0 2-2 4-3 5-4 5-5 6-6
These flags don't seem to exist in newer versions of Moses, and I
couldn't find anything equivalent in the decoder's help message. Is it
the case now that word alignments can only be written out to a totally
separate file ("-alignment-output-file FILE") or in an n-best list
format with some additional columns ("-n-best-list - 1
-print-alignment-info-in-n-best")? Or is there a new cocktail of
flags that I can use? I'd like to replicate the same output format as
before, if possible.
Relatedly, I think the documentation on statmt.org <http://statmt.org>
is a little inconsistent or maybe only partially updated. Cf.
http://www.statmt.org/moses/?n=Moses.AdvancedFeatures#ntoc3 , which
disallows --print-alignment-info, and
http://www.statmt.org/moses/?n=Moses.AdvancedFeatures#ntoc9 , which
still suggests using it.
Thanks in advance for any help you can provide!
Greg.
