Hi all,
If you do not have to use syntactic parser, it is possible to utilize a
discriminative parser for word reordering, such as STIR
(http://research.google.com/pubs/pub37163.html, but no implementation
available) or LADER
(http://www.phontron.com/paper/neubig12emnlp-reordering.pdf,
implementation available at https://github.com/neubig/lader).

Hi Maxim, hi all,
in an undergraduate class we were working on a automatic rule
extraction and source-side preordering system as a preprocessing step
for English- Japanese. At the moment I'm writing my BA thesis on this
stuff. It works with Moses and cdec and since it is just preprocessing
it should work with any other decoder.
If you exchange the parser and maybe some of the parameters it should
work for every language pair. We get BLEU score improvement in
intrinsic evaluation (right now with a 1,7 mio sentence eng-jap patent
corpus).
The idea came from Genzel
http://research.google.com/pubs/archive/36484.pdf
Also check our final presentation slides of our implemention @

Hi Maxim,
You can check this paper:
http://aclweb.org/anthology//P/P11/P11-2067.pdf
<http://aclweb.org/anthology/P/P11/P11-2067.pdf>
It says: "CKK uses the Dubey and Keller (2003) parser, which is
trained on the Negra corpus (Skut et al., 1997)."

I don't know of an implementation that's available for download and I
seem to remember that the parser they used was extremely difficult to
use or compile.
If you find out more, please let everyone know

Dear Moses community,
I am looking for a ready to use or easily customizable
implementation of pre-reordering algorithms for Moses? In
particular, I'm interested in language pairs with German as a
source language and a variety of languages as target, so probably
the best solution is syntax based.
As a starting point, I would consider the algorithm described in
(Collins et al., 2005), but I don't know if there is an
implementation available and which parser it relies on.
Thanks for your help beforehand,
Maxim Khalilov
