水利工程传统应急方案存在数字化程度低、内容关联性差、智能辅助决策不足等问题。本文利用知识图谱和深度学习技术,创建一种水利工程应急方案智能生成模式。首先基于风险防控手册及险情抢险应急方案等文本,提出应急方案知识图谱本体模型,构建应急方案知识图谱,实现应急方案文本中非结构信息的结构化表达。其次,基于水利工程巡检文本,利用BERT(Bi-directional Encoder Representation from Transformers)+BiLSTM+CRF(Bi-directional Long Short Term Memory with Conditional Random Fields)实体识别模型,智能识别巡检文本中的风险事件、工程等实体。最后,设计应急方案智能生成模板,通过多特征融合的实体对齐技术、知识检索与推理技术,实现应急方案的智能生成与推送。通过模型准确性分析以及“渠道渗漏”等实例验证,本文方法识别准确率高(F1值为96.21%),生成的应急方案可靠,可推广到水利工程应急抢险以及应急预案智能生成等应急管理工作中。 |
英文摘要: |
Traditional emergency plans for hydraulic engineering projects have problems such as low digitisation,poor content relevance and insufficient intelligent aid for decision-making.In this paper,we use the knowledge graph and deep learning technology to create an intelligent generation model of emergency plans for hydraulic engineering projects.Firstly,based on the text of risk prevention and control manual and the emergency plan,we propose a knowledge graph ontology model of emergency plan,construct a knowledge graph of emergency plan,and realise the structured expression of non-structural information in the text of emergency plan.Secondly,based on the water resources engineering inspection text,we use BERT (Bi-directional Encoder Representation from Transformers) + BiLSTM + CRF (Bi-directional Long Short Term Memory with Conditional Random Fields) entity recognition model to intelligently identify risk events,projects and other entities in the inspection text.Finally,an intelligent generation template for emergency solutions is designed,and through multi-feature fusion of entity alignment technology,knowledge retrieval and inference technology,the intelligent generation and pushing of emergency solutions is realised.Through the model accuracy analysis and the validation of examples such as “channel leakage”,this paper shows a high recognition accuracy (F1 value of 96.21%) and a reliable emergency plan generation,which can be extended to emergency management such as emergency rescue of hydraulic engineering projects and intelligent generation of emergency plans. |
