Abstract

Most of the event detection methods based on dependency parsing only focus on the single-hop connection of dependency syntax structure. It ignores the multi-hop connection between words, resulting in the lack of semantic information between trigger words and some related entities, which affects the efficiency of event detection. Therefore, this paper proposed an event detection model integrating multi-hop relation labels and dependency syntactic structure information to improve the recognition performance of event trigger words. This paper designed a new dependency syntax "multi hop tree" and multi hop relation label search algorithm to enhance the event-representation ability of core vocabulary. Furthermore, it used graph attention network to aggregate the multi-level word representation, which improved the event detection performance. Results on ACE2005 dataset show that this event detection method improves the performance of the benchmark model by nearly 2%.
