摘　　要：全国取用水平台整合是实现取用水业务“一网统管”的重要途径,但因拟整合的取用水业务系统繁多,信息资源分散,平台整合中存在一数多源、标准不统一、户证点关系不清晰等现实问题,为此尝试提出将知识图谱技术应用于平台整合过程,建设一套全国统一的数据库表结构标准,形成一套真实且唯一的户证点关系,构建一套智能且有效的监管数据产品。采用自顶向下的知识图谱构建方式,根据各系统的结构化数据,构造模式层中的本体及其相互关系,形成对应的概念模型和规则关系,再依照此模式从数据中抽取实体及关系,进行数据融合,构造数据层,并及时进行知识更新,完成全国取用水平台知识图谱的构建。最后基于统一规范的数据库表结构标准,依据对取用水户取用水行为的监管需求,开展时空尺度的数据信息统计分析,构建6类监管产品,形成取用水管控一张图。The integration of national water consumption platform is an important way to realize"integrated management"of water consumption business.However,there are many water consumption systems to be integrated,and the information sources are dispersed.In addition,there are some practical problems in platform integration,such as multiple sources,inconsistent standards,unclear relationship among accounts,licenses and points,etc.Therefore,this paper attempts to apply knowledge graph technology to the platform integration process,building a set of national unified database table structure standard,forming a set of real and unique relationship among accounts,licenses and points,and building a set of intelligent and effective regulatory data products.The top-down knowledge graph construction method is adopted,in which an ontology in the pattern layer and its mutual relationship can be built according to the structured data of each system,and corresponding conceptual model and rule relationship can be formed.The entity and relationship from the data are extracted,data fusion and data layer construction are carried out,and knowledge is timely updated.Thus,the construction of the knowledge graph of the national water consumption platform is completed.Finally,based on the unified and standardized database table structure standard,statistical analysis of data information on a spatial-temporal scale is carried out according to the water consumption behavior supervision demands of water users,and six types of supervision products are constructed to form a“chart”of water consumption control.
