Ontology-based Construction and Application of Knowledge Graph of Maritime Dangerous Goods

The wide range of Maritime Dangerous Goods (MDG) usually have complex attributes and take high risks when transporting. In order to secure the transport, MDG must be strictly packed, segregated and stowed according to the International Maritime Dangerous Goods Code (IMDG Code). This paper aims to realize the intelligent management of MDG transport. Firstly, analyzes the MDG ontology and then describe the concepts, individuals, properties, the relationship between concepts and individuals of MDG in detail based on ontology. Furthermore, a method and model for constructing the knowledge graph of maritime dangerous goods (KGMDG) are proposed. Finally, its possible application is explored in this paper. The KGMDG is able to work out the correlation between goods, and provides technical support for intelligent inquiry of MDG knowledge and automatic judgment of stowage and segregation. It is of great significance for making the storage and transportation strategies, the emergency plans, and for preventing accidents caused by dangerous goods.
