There are good examples for that, eg. https://github.com/moses-smt/mosesdecoder/blob/master/scripts/ems/example/config.hierarchical I can't find a good explanation of how to train a string-to-tree model. It's difficult to create a simple example for syntax models because you need to use external tools like parsers. > > > - In http://www.statmt.org/moses/download/sample-models.tgz is provided a > sample to "string-to-tree" model.
