Then , we binarize the English parse trees using the head binarization approach ( Wang et al. , 2007 ) and use the resulting binary parse trees to build another s2t system .
binarizing syntax trees to improve syntaxbased machine translation accuracy
Wei Wang Kevin Knight Daniel Marcu
To build the above s2t system , we first use the parse tree , which is generated by parsing the English side of the bilingual data with the Berkeley parser ( Petrov et al. , 2006 ) . Then , we binarize the English parse trees using the head binarization approach ( Wang et al. , 2007 ) and use the resulting binary parse trees to build another s2t system . For the U-trees , we run the Gibbs sampler for 1000 iterations on the whole corpus .
