Character-Level Chinese Dependency Parsing
Meishan Zhang, Yue Zhang, Wanxiang Che, Ting Liu · 2014
Recent work on Chinese analysis has led to large-scale annotations of the internal structures of words, enabling characterlevel analysis of Chinese syntactic structures.In this paper, we investigate the problem of character-level Chinese dependency parsing, building dependency trees over characters.Character-level information can benefit downstream applications by offering flexible granularities for word segmentation while improving wordlevel dependency parsing accuracies.We present novel adaptations of two major shift-reduce dependency parsing algorithms to character-level parsing.Experimental results on the Chinese Treebank demonstrate improved performances over word-based parsing methods.
