摘　　要：针对消防、应急处置过程中快速进行决策支持和方案制定的难点,提出储气库站场天然气泄漏及火灾事故的应急模型,该模型应用知识图谱作为风险表征手段,利用双向编码表示转换器(BERT)和双向长短时记忆模型条件随机场算法(BiLSTM-CRF),实现对文本信息的实体识别和关系抽取。利用Neo4j图数据库构建储气库站场天然气泄漏及火灾事故的应急知识图谱。结果表明:相较于传统的应急处置、消防策略研究方法,本文提出的储气库站场天然气泄漏及火灾事故应急模型不仅可以实现对储气库站场天然气泄漏及火灾事故的早期应急处置,还能够识别事故的风险传播路径,为消防应急指挥和应急决策提供支持。Aiming at the difficulty of rapid decision support and plan formulation in the firefighting and emergency response process,this article proposes an emergency model for gas leakage and fire accidents at gas storage facility sites.This model uses a knowledge graph as a means of risk characterization,employing Bidirectional Encoder Representations from Transformers(BERT)and Bidirectional Long Short-Term Memory Model Conditional Random Field algorithm(Bi-LSTM-CRF)for entity recognition and relationship extraction from textual intelligence.The emergency knowledge graph for gas leakage and fire accidents at gas storage facility sites is constructed using the Neo4j graph database.The results show that compared to traditional emergency handling and firefighting strategy research methods,the emergency model proposed in this paper for gas leakage and fire accidents at gas storage facility sites not only enables early emergency handling but also identifies the risk propagation paths of accidents,providing support for firefighting emergency command and emergency decision-making.
