Using compositional semantics and discourse consistency to improve Chinese trigger identification

作者：

Highlights：

• We employ the compositional semantics to infer unknown triggers.

• We impose the discourse consistency to recover missing trigger mentions.

• The morphological structures are better to represent the compositional semantics.

• The head morpheme is the key clue to infer unknown triggers.
