An Empirical Examination of Challenges in Chinese Parsing
Jonathan K. Kummerfeld, Daniel W. K. Tse, James Curran, Dan Klein · 2013
Aspects of Chinese syntax result in a dis-tinctive mix of parsing challenges. How-ever, the contribution of individual sources of error to overall difficulty is not well un-derstood. We conduct a comprehensive automatic analysis of error types made by Chinese parsers, covering a broad range of error types for large sets of sentences, en-abling the first empirical ranking of Chi-nese error types by their performance im-pact. We also investigate which error types are resolved by using gold part-of-speech tags, showing that improving Chinese tag-ging only addresses certain error types, leaving substantial outstanding challenges. 1
