... that exploits bracket- ing information (Wu and Ng, 1995). If any brackets for the Chinese sentence can be supplied as addi- tional input information, produced for example by a preprocessing ... formalisms were originally developed for the purpose of parallel corpus annotation, with applications for bracketing, alignment, and segmen- tation. This paper finds they are also useful...
