Metadata for Datasets and Relationships

This dataset contains two tables. One table contains metadata for "citable" datasets (datasets that have either a DOI or a compact identifier). The other table contains the relationships between each pair of datasets in the first table. <br> We generated this corpus of dataset metadata by crawling the Web to find pages with schema.org or DCAT metadata indicating that the page contains a dataset. The metadata for datasets includes information such as the dataset’s name, description, provider, creation date, Digital Object Identifiers (DOI), and more. Out of the 46 million dataset pages that have schema.org, we publish this subset of 4.3 million dataset-metadata entries that are citable. We also include an additional table on relationships between these datasets.

本数据集包含两张数据表。其一为「可引用数据集」的元数据（即带有数字对象标识符（Digital Object Identifier，简称DOI）或精简标识符的数据集）；其二为第一张表中各数据集两两之间的关联关系。
我们通过网络爬取获取本数据集的元数据语料库，筛选出带有schema.org或DCAT元数据且声明包含数据集的网页。数据集元数据涵盖数据集名称、描述、提供方、创建日期、数字对象标识符（DOI）等多项信息。在总计4600万个带有schema.org元数据的数据集网页中，我们选取其中430万个可引用数据集的元数据条目进行发布，并额外附带一张记录上述数据集间关联关系的数据表。
