摘　　要：城市道路网是由城市内各种道路组成的相互联络、交织成网状,且为城市提供空间通道的道路系统。随着我国经济及3S技术的发展,城市道路里程呈几何式增长,“数据爆炸,知识匮乏”的情况愈加突出。知识图谱作为一种使用语义网将概念、实体及两者进行形式化表达的一种知识系统,可实现“数据-知识”的转化。但目前地理领域内的知识图谱普遍存在缺失空间关系描述的问题,因此将知识图谱和地理数据的空间特征相结合,构建成基于城市道路数据的知识图谱。文中介绍地理知识图谱的概念、内涵及现状,分析城市道路知识图谱中空间关系的重要性,讨论构建道路知识图谱的关键技术,最后阐述该知识图谱的应用方向。本研究在地理信息领域有一定的通用性,可为推动的地理知识服务智能化的发展提供理论支撑。The urban road network is a system of interconnected and interwoven roads that provide spatial access to the city.In the last two decades,with the development of China’s economy and 3S technology,the mileage of urban roads has increased geometrically and the situation of“data explosion and knowledge scarcity”has become more and more prominent.As a knowledge system that uses the Semantic Web to formally represent concepts,entities and associated relationships,the Knowledge Graph enables the transformation of“data-knowledge”.However,the current knowledge graph in the field of geography generally suffer from a lack of spatial relationship descriptions,so this paper combines knowledge graph with the spatial features of geographic data to build knowledge graph based on urban road data.This paper introduces the concept,connotation and current situation of geographic knowledge graph,analyses the importance of spatial relationships in urban road knowledge graph,discusses the key technologies for building road knowledge graph,and finally explains the application directions of this knowledge graph.This study has some generality in the field of geographic information,and can promote the development of intelligent geographic knowledge services to a certain extent.
