Recent researches (Sun, 2011;Qian and Liu, 2012;Zheng et al., 2013;Zeng et al., 2013;Qian et al., 2015) also focus on the development of a joint model to perform Chinese word segmentation, POS tagging, and/or informal word detection.
to the best of our knowledge, no existing system can perform word segmentation, POS tagging, and NER simultaneously.
