Nugget Proposal Networks for Chinese Event Detection
[article]
2018
arXiv
pre-print
Preserved Fulltext
Then based on learned representations, trigger nuggets are proposed and categorized by exploiting character compositional structures of Chinese event triggers. ...
In this paper, we propose Nugget Proposal Networks (NPNs), which can solve the word-trigger mismatch problem by directly proposing entire trigger nuggets centered at each character regardless of word boundaries ...
Moreover, we sincerely thank all reviewers for their valuable comments. ...
