摘要: 建筑物空间分布模式是物质和社会经济功能等综合作用于地域形成的重要空间结构,以往研究多基于图同构方法利用规则识别分布模式,识别效率不高。知识图谱利用图模型表达实体和实体间关系,并支持高效推理获取图谱中特定子图模式。因此,本文试图结合知识图谱高效识别直线型建筑物模式。首先,利用属性图数据模型构建表达建筑物间邻近、相似和沿直线排列空间关系的知识图谱;其次,将直线排列识别的结构化规则表达为知识图谱推理的规则,基于规则推理识别直线模式。试验结果表明,本文方法能实现和已有方法相同的准确率和召回率,在包含1286个建筑物的数据集上识别效率能提高5.98倍。

Abstract: Building patterns are important urban structures that reflect the effect of the urban material and social-economic on a region. Previous researches are mostly based on the graph isomorphism method and use rules to recognize building patterns, which are not efficient. The knowledge graph uses the graph to model the relationship between entities, and specific subgraph patterns can be efficiently obtained by using relevant reasoning tools. Thus, we try to apply the knowledge graph to recognize linear building patterns. First, we use the property graph to express the spatial relations in proximity, similar and linear arrangement between buildings; secondly, the rules of linear pattern recognition are expressed as the rules of knowledge graph reasoning; finally, the linear building patterns are recognized by using the rule-based reasoning in the built knowledge graph. The experimental results on a dataset containing 1286 buildings show that the method in this paper can achieve the same precision and recall as the existing methods; meanwhile, the recognition efficiency is improved by 5.98 times.
