摘要
城市功能区的划分对于了解城市特点、协助城市管理和规划至关重要。传统的划分方法,如基于街区和网格的划分,已不能满足现代需求。为此,我们提出了一种以知识图谱为支撑的功能类别划分方法。首先,利用三角测量和缓冲区建立兴趣点(POI)和建筑物之间的关联。然后,通过实体和关系提取构建建筑物知识图谱。利用周围 POI 的语义特征作为推理规则,设计了一个由 Z 分数支持的功能类别分类模型。结果表明,建筑物功能类别划分的准确性很高,支持了城市功能区的细化和智能表达,为城市建设、规划和管理提供了支持。
Automatic Functional Classification of Buildings Supported by a POI Semantic Characterization Knowledge Graph
The division of urban functional zones is crucial for understanding urban characteristics and aiding in urban management and planning. Traditional methods, like dividing based on blocks and grids, are insufficient for modern demands. To address this, a knowledge-graph-supported method for building functional category division is proposed. Firstly, the associations between points of interest (POI) and buildings are established using triangulation and buffer zones. Then, a knowledge graph of buildings is constructed through entity and relationship extraction. A functional category classification model supported by the Z-score is designed using the semantic characterizations of surrounding POIs for inference rules. The results demonstrate high accuracy in building functional category division, supporting the refinement and intelligent expression of urban functional zones for urban construction, planning, and management.
