Yinlong Xiao, Zongcheng Ji, Jianqiang Li, Mei Han

Abstract: Highlights•Introducing dual-grained syntactic dependency information for Chinese NER.•Proposing a syntax-aware self-attention mechanism to integrate syntactic dependency relations.•Proposing a network to model and aggregate dual-grained syntactic information and contextual information.•Demonstrating the effectiveness of the proposed approach through four public Chinese NER datasets.
