Ubiquitous spatio-temporal data cross validation method and device based on knowledge graph

The invention provides a ubiquitous spatio-temporal data cross validation method and device based on a knowledge graph, and the method comprises the steps: obtaining multi-source spatio-temporal data, and unifying the coordinates and time of the multi-source spatio-temporal data; constructing a spatio-temporal knowledge graph based on the coordinate and time unified multi-source spatio-temporal data; and performing entity space information verification and entity time sequence information verification on the space-time knowledge graph to obtain high-quality space-time knowledge, and storing the space-time knowledge into a space-time database. According to the method, the problems that the quality of multi-source data is uneven, knowledge from different data sources is repeated, and association among the knowledge is not clear enough are solved. 本发明提供了一种基于知识图谱的泛在时空数据交叉验证方法及装置，包括：获取多源时空数据，并对多源时空数据的坐标和时间进行统一；基于坐标和时间统一的多源时空数据构建时空知识图谱；对时空知识图谱进行实体空间信息验证和实体时间序列信息验证，得到高质量时空知识，并将所述时空知识存入时空数据库。本发明缓解了多源数据质量良莠不齐、来自不同数据源的
