Hi, what's the major difference between the tuning process for a factored
phrase based system (i.e., surface+pos data) and a simple baseline phrase
based system?


Nothing, the tuning just optimise weights for feature functions.

If you decompose your translation so that it has multiple phrase tables and
generation models, then they are just extra feature functions with weights
to be tuned

Do I need to organize the dev set the same way as the training set (i.e.,
surface|pos)?

Yes

Is there a tutorial on the moses website on this topic?

Maybe this

Thanks!
