Relabeling syntax trees to improve syntax-based machine translation quality
Bryant Huang, Kevin K. Knight · 2006
We identify problems with the Penn Treebank that render it imperfect for syntaxbased machine translation and propose methods of relabeling the syntax trees to improve translation quality.We develop a system incorporating a handful of relabeling strategies that yields a statistically significant improvement of 2.3 BLEU points over a baseline syntax-based system.
