3 Using all rule table, our joint method significantly outperforms the best single system SF by +1.96 and +1.66 points on MT04 and MT05 respectively, and also outperforms the lattice-based system by +1.46 and +0.93 points.
the 8 tokenization features have small impact on the lattice system, probably because the tokenization space limited  Table 3: Effect of tokenization features on Chinese-English translation task. "
