融入篇章信息的文学作品命名实体识别(Document-level Literary Named Entity Recognition)

no code implementations CCL 2021 Yuxiang Jia, Rui Chao, Hongying Zan, Huayi Dou, Shuai Cao, Shuo Xu

“命名实体识别是文学作品智能分析的基础性工作, 当前文学领域命名实体识别的研究还较薄弱, 一个主要的原因是缺乏标注语料。本文从金庸小说入手, 对两部小说180余万字进行了命名实体的标注, 共标注4类实体5万多个。针对小说文本的特点, 本文提出融入篇章信息的命名实体识别模型, 引入篇章字典保存汉字的历史状态, 利用可信度计算融合BiGRU-CRF与Transformer模型。实验结果表明, 利用篇章信息有效地提升了命名实体识别的效果。最后, 我们还探讨了命名实体识别在小说社会网络构建中的应用。”

Knowledge-injected Prompt Learning for Chinese Biomedical Entity Normalization

no code implementations23 Aug 2023 Songhua Yang, Chenghao Zhang, Hongfei Xu, Yuxiang Jia

However, existing research falls short in tackling the more complex Chinese BEN task, especially in the few-shot scenario with limited medical data, and the vast potential of the external medical knowledge base has yet to be fully harnessed.
