摘要
在核电领域的知识管理过程中,需要使用命名实体识别技术抽取高质量语义实体,以进行核电领域文本的智能分析和处理。在现有研究的基础上,通过增强网络对上下文信息的提取能力,提升模型对嵌套命名实体的识别准确率。经实验验证,所提方法较现有方法在准确率与召回率指标上提升显著,与BiFlaG网络对比,准确率提高9.52%,召回率提高8.51%,F_(1)值提高9.02%。所提方法对嵌套命名实体识别优于BiFlaG等网络。
In the process of knowledge management in nuclear power,it’s necessary to use named entity recognition to extract high-quality semantic entities for intelligent analysis and processing of text in nuclear power.On the basis of existing research,the recognition precision rate of the model for nested named entities is improved by enhancing the ability of the network rate to extract context information.The experimental results show that the proposed method improves the precision and recall rate significantly compared with the existing methods.Compared with the BiFlaG network,the precision rate is increased by 9.52%,the recall rate is increased by 8.51%,and the F_(1) value is increased by 9.02%.
