Abstract

The fine-grained event detection task at the sentence level aims at identifying and classifying triggers. To solve the problem of over-smoothing and lack of dependency type information in existing event detection methods, this paper proposed an event detection method based on dependency information and graph convolutional network(GCN). This method firstly used bi-directional long short-term memory(Bi-LSTM) networks to encode the sentence, and constructed a multi-order syntactic graph and a dependent syntactic graph based on the dependency analysis. Then it used GCN to aggregate the sentences' dependency information, which effectively utilized the multi-hop information and the dependent type information. On automatic content extraction(ACE) dataset, the proposed method achieved 81.7% and 78.6% F1 values in the two subtasks of trigger identification and classification. Results show that the proposed method can capture event information in sentences more effectively, and improve the effect of event detection.
