We investigate the possibility of exploit- ing character-based dependency for Chi- nese information processing. As Chinese text is made up of character sequences rather than word sequences, word in Chi- nese is not so natural a concept as in En- glish, nor is word easy to be defined with- out argument for such a language. There- fore we propose a character-level depen- dency scheme to represent primary lin- guistic relationships within a Chinese sen- tence. The usefulness of character depen- dencies are verified through two special- ized dependency parsing tasks. The first is to handle trivial character dependencies that are equally transformed from tradi- tional word boundaries. The second fur- thermore considers the case that annotated internal character dependencies inside a word are in...
