Webtion (NER) to enhance span boundary detection and type classi cation. However, to further understand the generalizability and e ectiveness of gazetteers, the NLP community still lacks a systematic analysis of the gazetteer-enhanced NER model. In this paper, we rst re-examine the e ectiveness several common practices of the gazetteer-enhanced NER Webflat NER, achieving 77.1% and 78.4% respec-tively in terms of F-score, without any external knowledge resources. 1 Introduction Named entity recognition (NER) is a task of find-ing entities with specific semantic types such as Protein, Cell, and RNA in text. NER is generally treated as a sequential labeling task, where each

However, the widely-used sequence labeling framework is usually difficult to detect entities with nested structures. The span-based method that can easily detect nested entities in different subsequences is naturally suitable for the nested NER problem.
