为了开发科学技术领域的创新解决方案，日本科学技术厅（JST）出版了JGLOBAL knowledge（JGk），其中提供了JST自1957年以来积累的论文、专利、研究人员信息、技术词库和科学数据，作为链接开放数据。所有数据集的总数超过155亿个三元组，JGk网站提供了一个SPARQL端点来访问这些数据集。本文描述了构建大规模关联数据的模式设计的几个问题，以及链接到外部数据集（如DBpedia）的方法。最后，我们指出了性能问题和未来的工作。
In order to develop innovative solutions in science and technology, Japan Science and Technology Agency (JST) has published JGLOBAL knowledge (JGk), which provides papers, patents, researchers’ information, technological thesaurus, and scientific data, which have been accumulated by JST since 1957 as Linked Open Data. The total of all datasets surpasses 15.5 billion triples, and the JGk website provides a SPARQL endpoint to access the datasets. This paper describes several issues on schema design to construct such a large-scale Linked Data, and methods for linking to external datasets like DBpedia. Finally, we indicate performance problems and the future works.
