摘要 自从知识图谱的概念被提出来以后,研究人员一直致力于对知识图谱的深入研究,以挖掘此项技术的潜力,本文从知识图谱的架构入手介绍了知识图谱构建的步骤和涉及的核心技术,进而进行城市知识图谱的搭建。以兰州市为例,获取城市中餐饮、医疗、教育、旅游景点等领域相对全面的数据让系统最终的实用性与真实性有所保障。考虑到用户的使用体验,设计了前端界面完成知识图谱可视化,用户可以在客户端对知识图谱中的数据进行交互了解城市不同领域的内容结构,展现了该系统的实用性。 Since the concept of knowledge graph was proposed,researchers have been focusing on in-depth research on knowledge graph to explore the potential of this technology.This article introduces the steps and core technologies involved in constructing knowledge graph from the perspective of knowledge graph architecture,and then constructs urban knowledge graph.Taking Lanzhou City as an example,this article aims to obtain information on urban catering,healthcare,and education,the relatively comprehensive data in fields such as tourist attractions ensures the ultimate practicality and authenticity of the system.Considering the user experience,a front-end interface has been designed to visualize the knowledge graph.Users can interact with the data in the knowledge graph on the client to understand the content structure of different fields in the city,demonstrating the practicality of the system.
