Re: [Moses-support] How to train a model using multiple phrase-tables and multiple language models?

Mon, 29 Feb 2016 08:44:36 -0800

Last I checked (18+ months ago), EMS didn't handle the 2TM-2LM setup natively. I had to modify the moses.ini file manually, and then launch the tuning step manually as well. It's straightforward, but annoying, so I wrote a bash wrapper to do it. I just uploaded it to github for you:

https://github.com/amittai/public-code/blob/master/amittai-tune-moses-2tm-2lm.sh

This assumes you've already got 2 fully trained MT systems, and tunes a multi-model system that uses 2 TM, 2LM (n.b. but only one reordering model).

Cheers,

Dear Moses devs/users,

Is the some documentation / tutorial on how to run "alternative decoding paths" from Birch, Osborne, & Koehn (2007), i.e. from http://homepages.inf.ed.ac.uk/abmayne/publications/acl2007ccg.pdf and http://arxiv.org/pdf/1401.6876.pdf ?

After having two phrase-tables and two language models, what should I do to the moses.ini file such that it takes 2 phrase-tables and 2 language models?

And afterwards, how should I tune it? Is the tuning functionality for alternative decoding path already in mert-moses.perl or other related tuning scripts?

Thanks in advance for the pointers/links/suggestions!

Regards,
Liling
