Improving Part-of-speech Tagging for Context-free Parsing
Xiao Dong Chen, Chunyu Kit · CityU Scholars · 2011
In this paper, we propose a factored parsing model consisting of a lexical and a constituent model. The discriminative lexical model allows the parser to utilize rich contextual features beyond those encoded in the context-free grammar (CFG) in use. Experiment results reveal that our parser achieves statistically significant improvement in both parsing and tagging accuracy on both English and Chinese. © 2011 AFNLP
