  title={Fusing Heterogeneous Factors with Triaffine Mechanism for Nested Named Entity Recognition},
  author={Zheng Yuan and Chuanqi Tan and Songfang Huang and Fei Huang},
Nested entities are observed in many domains due to their compositionality, which cannot be easily recognized by the widely-used sequence labeling framework.A natural solution is to treat the task as a span classification problem.To learn better span representation and increase classification performance, it is crucial to effectively integrate heterogeneous factors including inside tokens, boundaries, labels, and related spans which could be contributing to nested entities recognition.To fuse…
