SCTB is a phrase structure based Chinese treebank. The raw sentences are selected from Chinese scientific papers. Our annotation process follows that of CTB (Xue et al., 2005) with an exception of the segmentation standard. We apply a Chinese word segmentation standard based on character-level POS patterns (Shen et al., 2016). The first version of release contains 5,133 sentences (138,781 words).
