Abstract：The non-projective structure refers to the phenomenon that the word nodes on the dependency tree are misplaced with different word sequence in the original sentence. It has not been discussed in Chinese, following only the projection principle in the construction of Chinese dependency corpus. In this paper, we construct a Chinese abstract meaning representation (AMR) corpus of 10 149 sentences, in which 31.62% sentences have non-projective structures. Then we distinguish the three main types of the non-projective structures, modal words, topicalization and the component separation. Finally, we provide the solutions for the structures in the AMR parsing.
