5 Conclusion
</SectionTitle>
    <Paragraph position="0"> We have demonstrated that relabeling syntax trees for use in syntax-based machine translation can signi cantly boost translation performance. It is na ve to assume that linguistic resources can be immediately useful out of the box, in our case, the Penn Treebank for MT. Rather, we targeted features of the PTB tagset that impair translatability and proposed relabeling strategies to overcome these weaknesses.</Paragraph>
    <Paragraph position="1"> Many of our ideas effectively raised the BLEU score over a baseline system without relabeling. Finally, we demonstrated through an additive system that relabelings can be combined together to achieve an even greater improvement in translation quality.</Paragraph>
