科学数据资源聚合机制研究

Research on Science Data Resource Aggregation Mechanism

根据科学数据资源的内在结构和聚合程度,科学数据资源聚合可分为基于数据的聚合、基于信息的聚合、基于知识的聚合。三个层次的科学数据资源聚合机制分别以分布式构建技术、元数据互操作技术、本体技术为基础,文章介绍不同聚合机制的内涵与特征,并辅以典型应用予以具体分析。

According to the inner structure and aggregation degree of science data resources, science data resource aggregation can be divided into resource aggregation based on data,resource aggregation based on information,resource aggregation based on knowledge. Science data resource aggregation mechanisms of the three levels are respectively based on distributed building technology,metadata interoperability technology,and ontology technology. This paper introduces the connotation and characteristics of different resource aggregation mechanisms,then analyzes them with typical applications.
