NerCo: A Contrastive Learning Based Two-Stage Chinese NER Method

IJCAI 2023poster

Sequence labeling serves as the most commonly used scheme for Chinese named entity recognition(NER). However, traditional sequence labeling methods classify tokens within an entity into different classes according to their positions. As a result, different tokens in the same entity may be learned wi…
