Study on construction of knowledge graph for urban underground pipeline information based on Neo4j
In order to better support the detection operation of urban underground pipelines and manage the underground pipeline knowledge database more systematically and flexibly,based on relevant domestic standards and specifications,the knowledge graph of urban underground pipeline information was established through entity extraction and knowledge integra-tion.The knowledge graph was stored in the graph database Neo4j,and an auxiliary decision-making framework of detection based on data-knowledge fusion was proposed to provide the real-time and accurate knowledge query interface.The research results show that the constructed knowledge graph can assist the detection decision-making process of underground pipeline excavation engineering,and promote the construction of underground pipeline data-knowledge fusion detection system.
