Besides the usual local features such as the character-based ones (Xue and Shen, 2003;Ng and Low, 2004), many non-local features related to POSs or words can also be employed to improve performance.
experiments of Ng and Low (2004) on CTB 3.0 also shown the similar trend, where they obtained F-measure 0.952 on segmentation, and 0.919 on Joint S&T.
