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 · IWSLT · 2009
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 translation. 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 sentences described respectively by Head-driven Phrase Structure Grammar and Predicate-Argument Structures. We report the results of our system on both the development and test sets.
