Constructing a Clustering Model Using Semantic Clouds Distance and Its Application on the “Connectivity” of the “Twenty-First-Century Maritime Silk Road”

The “twenty-first-century Maritime Silk Road” is of great significance to the construction of China’s marine environmental security. This paper focuses on the core policy of the Silk Road—the “connectivity.” In order to cluster the countries along the line based on the connectivity, this paper introduces the cloud model theory, puts forward the new concept “semantic clouds distance” and its calculation equation named location- and shape-based cloud distance measurement (LSCM), and then constructs the cluster model. Finally, the results are tested by similarity between the Association of Southeast Asian Nation (ASEAN) countries and the clustering center. The method proposed in this paper can be effectively applied to cluster analysis and research of human problems such as connectivity and provide research ideas for similar problems.
