Moreover, compared with the Treebank Chinese tagset, the CKIP tagset pro-vides more fine-grained tags, including many tags with semantic information (e.g., Nc for place nouns, Nd for time nouns), and verb transitivity and subcategorization (e.g., VA for intransitive verbs, VC for transitive verbs, VK for verbs that take a clause as object).
using the POS features in combination with the lexical features in target language will cause another sparseness problem in the phrase table, since one source phrase would map to multiple target ones with different POS sequences.
