... (Zhang and Clark, 2007) and (Jiang et al., 200 8a) . We propose an Integer Linear Programming (ILP) formulation of word segmentation, which is nat- urally viewed as a word-based model for CWS. Character-based ... times faster than searching in a raw space pruned with beam-width 5. Tagging accuracy is moderately improved as well. For Chinese word segmentation (CWS), which can be formulated as character tagging, ... tagging efficiency is our main consideration in our work on POS taging. The proposed constrained taggers as described above can achieve near state-of-art POS tagging accuracy in a much more efficient manner. 5.4...
