... (9) Therefore, the TAT-based translation model can be decomposed into four sub-models: 1. parse model: Pr(T (f J 1 )|f J 1 ) 2. detachment model: Pr(D|T(f J 1 ), f J 1 ) 3. TAT selection model: ... TATs to transform the tree into a tar- get string. Our experiments show that the TAT-based model significantly outper- forms Pharaoh, a state-of-the-art decoder for phrase-based models. 1 I...
