Hi Fabienne! Yes, you can find an implementation of GHKM minimal rule extraction (Galley et al., 2004) by Philip Williams in this dir:
moses/scripts/training/phrase-extract/extract-ghkm Philip does not seem to have provided a documentation in this dir. Yet you can just run make to generate the executable and look into extract-ghkm.cpp for the file requirements. If you try it on Moses, since it currently only extracts minimal rules and not composed rules, you may not get fancy BLEU scores. Alternatively, Liang Huang and Haitao Mi have a python implementation in assembla, which extracts both minimal and composed rules. And you can google it out. Pre- and post-processing scripts are needed since it accepts and outputs files differently from Moses does. If you are interested, I can send you my scripts so that you don't need to reinvent the wheel. We are now experimenting with different rule extraction and scoring strategies on French-English translation and Chinese-English translation (Robert and me). If you are interested, let us discuss in more detail. Cheers, Yang Gao On Tue, Jul 5, 2011 at 3:30 PM, Fabienne Braune <[email protected]>wrote: > Hello, > > ghkm seems to be implemented for moses.
