hi henry that model is interesting but in practise it gives quite poor results on its own. You need to do multiple decoding paths to get good results. This is explained in http://www.statmt.org/moses/?n=Moses.FactoredTutorial#ntoc5 The paper on factored translation shows the results for this model http://www.iccs.inf.ed.ac.uk/~pkoehn/publications/emnlp2007-factored.pdf
