Hierarchical clustering-based data label system construction method and system

The invention relates to the technical field of data processing, and discloses a hierarchical clustering-based data label system construction method and system.The method comprises the following steps: extracting sub-data attributes based on data objects sorted out from real environment data and a relationship between the data objects, abstracting the sub-data attributes into a graph structure, and constructing a hierarchical clustering-based data label system; and automatically clustering the graph structure by using a hierarchical clustering algorithm to generate a sub-data label category system. According to the method, the following problems in the prior art are solved: data islands and chimney standing phenomena are relatively common, and flexible circulation and on-demand combined application of data in each business field are difficult to realize. 本发明涉及数据处理技术领域，公开了一种基于层次聚类的数据标签体系构建方法及系统，该方法，基于现实环境数据中梳理出的数据对象、数据对象之间的关系，抽取出子数据属性，然后将子数据属性抽象为图结构，再运用层次聚类算法对图结构进行自动聚类，生成子数据标签类目体系。本发明解决了现有技术存在的以下问题：数据孤岛、烟囱林立现象
