摘要
科学数据的语义异构是数据集成共享的主要瓶颈。数据本体是解决数据语义异构的有效方法。首先在系统分析地学数据特征的基础上,提出地学数据本体的总体架构,重点研究地学数据本质内容本体和形态本体,并构建了地学数据本体库。进一步结合科学数据集成的需求,提出基于地学数据本体的数据集成总体流程。在此基础上,以科技基础性工作专项产出的科学数据为例,开展地学数据本体支持下的科学数据集成方法应用研究,证明本方法的可行性和有效性。
Semantic heterogeneity of scientific data is main bottleneck for its integration and sharing.Data Ontology is an effective way to solves mantic heterogeneity of data.On the basis of systematic analysis of geodata characteristics,this paper puts forward the overall architecture of GeoData Ontology(GDO)and mainly studies essential characteristics ontology and morphological characteristics ontology of geodata and constructs GDO.Then,combining with the demand of scientific data integration,this paper puts forward the overall flow of data integration based on GDO.In the last part,this paper takes theexampleofscientific data ofNational Special Program on BasicWorksfor Science and Technology of China,researches application of scientific data integration method based on GDO andvalidates the feasibility and effectiveness of the proposed method.
