Hello,?
I need help to do the alignment using Giza++ and Moses. I was successfully installed and compiled Giza++ and Moses on Cygwin. I already search through the internet how to do alignment using Giza++ and Moses and found a lot of information. The problem is I don't have an idea where I should start. Is it possible if I do the alignment using the corpus that I create by myself?
Thank you.

I don't know anything about multi-model. Michael Denkowski seemed to
have made a few changes
