Construction Method and Application Demonstration of Island Management Spatiotemporal Knowledge Graph:A Case Study of Guangdong Province
摘要
Abstract
As the second marine economic zone,islands serve as crucial platforms for expanding marine economies and development spaces.Currently,China is putting forward increasingly refined require-ments for the protection,development,and management of islands.To better understand and express island knowledge,and to explore the relationships and dynamic evolution characteristics among island spatial entities,this paper proposes a construction method of island management spatiotemporal knowl-edge graph based on multi-source data.An ontology model of the island management spatiotemporal knowledge graph is constructed using a"top-down and bottom-up"approach.Taking Guangdong Prov-ince as an example,relevant entities,relationships,and attribute information are extracted from multi-source heterogeneous data.Knowledge is integrated through text alignment and spatial disambiguation methods,and the knowledge triples are stored using the graph database Neo4j.This paper preliminarily explores the application of the Island management spatiotemporal knowledge graph in the GIS field,re-alizing geographic retrieval and knowledge navigation functions of the spatiotemporal graph.This con-tributes to a better understanding of the spatiotemporal characteristics and change patterns of islands,providing an application example for the construction of geographic knowledge graphs in the island do-main.关键词
