The Chinese language is characterized by the lack of formal devices such as morphological tense and number that often provide important clues for syntactic processing tasks. While state-of-theart tagging systems have achieved accuracies above 97% on English, Chinese POS tagging has proven to be more challenging and obtained accuracies about 93-94% (Tseng et al., 2005b; Huang et al., 2007, 2009; Li et al., 2011).
