hi jie, 1. you're correct. the only language model avaiable using vs05 is the internal LM, which only supports up to 3-gram. u're welcome to change the code to support more. IRSTLM is not aviable for VS05, and i'm not happy with the windows version of SRILM because it's difficult to compile & doesn't support some things we need, like compressed files etc. 2. the generation step is described in http://www.iccs.inf.ed.ac.uk/~pkoehn/publications/emnlp2007-factored.pdf the model can be created using the moses training scripts, described in http://www.statmt.org/moses/?n=FactoredTraining.HomePage Hieu Hoang www.hoang.co.uk/hieu

I am studying Moses and found out that in VS05, Moses uses the internal language model rather than SRILM. And it turns out that the internal LM can only handle up to 3-grams. Does it mean in order to process n-grams with n>3, I have to use the SRILM or IRSTLM? BTW, what is Joint & Skip LM Model? 2. What is a generation table? As far as I know, the hypothesis is associated with a probability score multiplied with the translation, distortion and language model cost. The hypothesis with a highest probability score is the best possible translation. Where does a generation table come into play? and How to generate a generation table? Thanks in advance Jie -- ================================= Jie Wu Homepage: http://www.jiewu.info
