Unified named entity recognition as word-word relation classification
So far, named entity recognition (NER) has been involved with three major types, including
flat, overlapped (aka. nested), and discontinuous NER, which have mostly been studied …

A unified generative framework for various NER subtasks
Named Entity Recognition (NER) is the task of identifying spans that represent entities in
sentences. Whether the entity spans are nested or discontinuous, the NER task can be …

Cpt: A pre-trained unbalanced transformer for both chinese language understanding and generation
In this paper, we take the advantage of previous pre-trained models (PTMs) and propose a
novel Chinese pre-trained unbalanced transformer (CPT). Different from previous Chinese …

Locate and label: A two-stage identifier for nested named entity recognition
Named entity recognition (NER) is a well-studied task in natural language processing.
Traditional NER research only deals with flat entities and ignores nested entities. The span …
