BoningKnife: Joint Entity Mention Detection and Typing for Nested NER via prior Boundary Knowledge [article]

Huiqiang Jiang, Guoxin Wang, Weile Chen, Chengxi Zhang, Börje F. Karlsson
2021 arXiv   pre-print
In this paper, we propose a joint entity mention detection and typing model via prior boundary knowledge (BoningKnife) to better handle nested NER extraction and recognition tasks.  ...  Most existing nested NER methods traverse all sub-sequences which is both expensive and inefficient, and also don't well consider boundary knowledge which is significant for nested entities.  ...  Method Case Study and Attention Weight Visualization Conclusion In this paper we propose a novel joint entity mention detection and typing model via prior boundary knowledge for the nested NER task  ...
