Span-Prototype Graph Based on Graph Attention Network for Nested Named Entity Recognition

Span-Prototype Graph Based on Graph Attention Network for Nested Named Entity Recognition

Named entity recognition, a fundamental task in natural language processing, faces challenges related to the sequence labeling framework widely used when dealing with nested entities. The span-based method transforms nested named entity recognition into span classification tasks, which makes it an e...
