Construction of Knowledge Graphs for Maritime Dangerous Goods

Abstract

Dangerous goods occupy an important proportion in international shipping, and government and enterprises pay a lot of attention to transport safety. There are a wide variety of dangerous goods, and the knowledge involved is extensive and complex. Organizing and managing this knowledge plays an important role in the safe transportation of dangerous goods. The knowledge graph is a mass of brand-new knowledge management technologies that provide powerful technical support for integrating domain knowledge and solving the problem of the “knowledge island.” This paper first introduces the knowledge of maritime dangerous goods (MDG); constructs a three-layer knowledge structure of MDG, dividing this knowledge into two categories; uses ontology to express the concepts, entities, and relations of MDG; and puts forward the representation methods of the conceptual layer and entity layer and designs them in detail. Finally, the knowledge graph of maritime dangerous goods (KGMDG) is constructed. Furthermore, we demonstrate the knowledge visualization, retrieval, and automatic judgment of segregation requirement based on KGMDG. It is proved that KGMDG does not only help to simplify the retrieval process of professional knowledge and to promote intelligent transportation but is also conducive to the sharing, dissemination, and utilization of MDG knowledge.

Research on the Construction of a Knowledge Graph and Knowledge Reasoning Model in the Field of Urban Traffic

“…They mainly integrate Chinese encyclopedia websites (such as Baidu Encyclopedia, HDwiki and Chinese Wikipedia). In addition to general purpose large-scale knowledge graphs, various industries are also building knowledge graphs in vertical fields, such as a knowledge graph for the medical field [9], a knowledge graph of breast cancer [10], and a knowledge graph of maritime dangerous goods [11].…”

Systematic Knowledge Management of Construction Safety Standards Based on Knowledge Graphs: A Case Study in China

“…In the legal domain, KG is also used to manage case knowledge [52]. The maritime hazardous materials knowledge graph enables automatic determination of hazardous materials in isolation [53]. In addition, KG is used for knowledge management in education [54].…”

Construction of Space Object Situation Information Service Based on Knowledge Graph

“…Based on these open KGs, various industry KGs that are applicable to different industries (such as finance, agriculture, geography, meteorology, medicine and education) have also been constructed. These include the Gene Ontology [25] and Traditional Chinese Medicine KG [26] for biomedicine, Crop Diseases and Insect Pests [27] for agriculture, FOAF for social relations [28] and KGs for social networks [29], GeoNames Ontology and GeoKG for geospatial big data [30], [31], OSM Semantic Network [32]- [34], transportation KG [35], [36], KGs for multimedia conferencing process management [37], etc.…”

“…Understanding the world from different levels is a cognitive mechanism inherent in humans [39]. Therefore, as shown in FIGURE 2, by studying the multi-granularity related content [35], [40], [41], this study proposes a multi-granularity knowledge structure to realize a description of data, information, and knowledge at different scales in SOSKG. The multi-granularity knowledge structure of SOSKG includes a macro knowledge layer, core knowledge layer and micro knowledge layer, each being interconnected.…”
