Cost-sensitive Regularization for Label Confusion-aware Event Detection (P19-1)
Copied to clipboard
| Challenge: | Recent advances in event detection focus on wordwise classification with one NIL class for tokens do not trigger any event. |
| Approach: | They propose a cost-sensitive regularization method which penalizes more on mislabeling . they propose two estimators which can effectively measure such label confusion based on instance-level statistics . |
| Outcome: | The proposed method can improve the performance of different models in English and Chinese event detection. |
