Incorporating constituent structure constraint into discriminative word alignment
Wenhan Chao, Zhoujun Li · 2007
We introduce an approach to incorporate the constituent structure constraint into a discriminative word alignment model by presenting the constituent constraint in an explicit way and using three operations to ensure the constraint when search the best word alignment. In this way, we will be able to make use of the weak order constraint induced by the inversion transduction grammars (ITG), as well as the flexibility of the discriminative word alignment framework to incorporating any other useful features. 1
