知识图谱技术在港口多元危险货物储存中的应用

Applicat ion of knowledge graph technology in storage of dangerous goods in ports

针对危险货物结构体系庞大、危险货物知识比较分散、查询程序繁琐、储存隔离判断复杂等问题,以港口储存危险货物为例,研究港口多元危险货物储存知识图谱的构建方法。首先梳理了港口多元危险货物储存知识结构,将危险货物根据知识属性和操作措施等特征进行归类,根据知识表示形式分为直接知识表示和间接知识表示;然后提取危险货物概念、货物实体、货物属性、货物间事实关系,利用本体表示法表示货物知识并建立知识间的关联;在此基础上通过自定义知识推理规则进一步挖掘隐含知识,构建了港口多元危险货物储存知识图谱;最后探讨了基于该知识图谱的应用,利用实际案例验证了知识图谱在简化知识查询程序、展示危险货物知识结构、储存隔离判断等方面的有效性。

In view of the huge structural system of dangerous goods,the relatively scattered knowledge,and the complicated inquiry procedures and the difficult judgment of storage isolation,the method of constructing the knowledge graph of dangerous goods storage in the port was studied by taking the storage of dangerous goods in the ports as an example.Firstly,the knowledge structure of dangerous goods storage in ports was sorted out,and the dangerous goods were classified according to the characteristics of knowledge attributes(direct or indirect)and handling ways.Then,the concept,the entity,the attributes of dangerous goods,and the factual relationship among these goods were obtained.The ontology representation was used to represent the knowledge of goods and the relationship between the knowledge was established.On this basis,the knowledge graph of multi dangerous goods storage in ports was constructed.Finally,the application of the knowledge graph was discussed,and the effectiveness of the knowledge graph in simplifying the knowledge query procedure and storage isolation judgment was verified by a practical case.
