The UOT system: improve string-to-tree translation using head-driven phrase structure grammar and predicate-argument structures

Xianchao Wu, Takuya Matsuzaki, Naoaki Okazaki, Yusuke Miyao, Jun’ichi Tsujii

We present the UOT Machine Translation System that was used in the IWSLT-09 evaluation campaign. This year, we participated in the BTEC track for Chinese-to-English trans- lation. Our system is based on a string-to-tree framework. To integrate deep syntactic information, we propose the use of parse trees and semantic dependencies on English sen- tences described respectively by Head-driven Phrase Struc- ture Grammar and Predicate-Argument Structures. We re- port the results of our system on both the development and test sets.
