摘要
地学数据资源具有多源、分散、异构等特征,为了能够充分共享和利用地学数据资源,必须有效集成并建立地学数据库,但是传统地学数据建库方法存在着难以系统地认知建库对象,缺乏统一的语义支撑等问题。针对这些问题,本文提出并定义了地学数据本体模型、概念体系及其构建方法,阐述了基于地学数据本体的数据建库方法和流程。该方法在数据本体明确语义的支撑下,抽取出完善的数据实体关系模型,实现多源、异构数据的映射、转换与规范化处理,并利用数据本体准确表达数据库的语义信息。最后以贵州岩溶地下水数据库构建为例,进行了方法的应用验证。研究表明:地学数据本体通过对数据资源全生命周期共识概念、属性、实例及其关系的形式化描述,可以有效克服传统地学数据建库方法的缺陷,更好地支撑和促进地学数据资源的集成建库。
Geoscience data(Geo-data)resources have many characteristics,such as multi-sources,dispersed and heterogeneous.In order to fully share and make use of Geo-data,such datasets must be effectively integrated into databases.For traditional methods of Geo-data integration and database construction,they are difficult to systematically cognize target objects and lack unified semantic support.Firstly,this paper proposes the model,concept architecture and construction method of the Geo-data ontology.And then the data integration and database building method and process are introduced based on Geo-data ontology.Finally taking Guizhou karst groundwater database construction as an example,the proposed method is applied and verified.The result shows that Geo-data ontology which is the formal description of consensus concepts,instances,attributes and relations related to the whole life cycle of Geo-data resources,can effectively support and promote Geo-data integration and database building,Geo-data exchanging,sharing and application.
