Currently, research efforts have derived useful discrete features from dependency structures (Sasano and Kurohashi, 2008;Cucchiarelli and Velardi, 2001;Ling and Weld, 2012) or structural constraints (Jie et al., 2017) to help the NER task.
furthermore, every entity type (i.e., row) has a most related dependency relation (with more than 17% occurrences).
