基于知识规则集的城市工程地质数据库质量控制

摘要

通过对现有数据库质量控制理论和方法的研究,分析了城市工程地质数据库特点,并在挖掘城市工程地质数据库中空间数据的拓扑一致性和属性数据逻辑一致性的基础上,建立了面向城市工程地质数据库的知识规则集,进而提出了基于知识规则集的城市工程地质数据库质量控制的技术方法体系.最后,以南京市工程地质数据库为例,基于该质量控制方法进行数据库质量控制实验,验证了该方法的正确性和有效性.%Through studing the existing theory and method of database quality control, the characteristics of urban engineering geology database are analyzed, and the knowledge rule set facing urban engineering geology database is established based on diging the topological consistency of spatial data and the logical consistency of attribute data, and then, the technical methodology of the quality control of urban engineering geology database based on the knowledge rule set is proposed. Finally, with this quality control method, the test on urban engineering geology database of Nanjing is carried out, and the correctness and the validity of this method are proved.
