论文摘要
Microsoft Academic Graph（MAG）已经研究了有关其对书目评估的适用性的很多研究。 2021年5月，宣布将于2021年12月31日退休。此后不久，非营利组织Ouresearch旨在提供“全球研究系统的完全开放的目录”，宣布他们将保留并纳入最后一个完整的MAG语料库，仅排除了持续数据，并排除了持续的数据，并继续持续并希望改进它。在2022年1月推出Openalex之后，很感兴趣的是知道MAG数据的有用性是否在Openalex中保留甚至改善。为此，我们比较了MAG和Openalex的书目分析（尤其是引用的现场和时间归一化）与文献分析相关的元数据： - 多年来文档的覆盖范围， - 书目数据的一致， - 参考文献的参考数量，每个文档的参考数量， - 每个文档的类型和分布类型的分布和分类分布和分布的分布。
Microsoft Academic Graph (MAG) has been studied a lot concerning its suitability for bibliometric evaluations. In May 2021, it was announced that it would retire on December 31, 2021. Soon after that, the non-profit organization OurResearch, aiming at providing 'a fully open catalog of the global research system', announced they would preserve and incorporate the last full MAG corpus, only excluding patent data, and to continue and hopefully improve it. After the launch of OpenAlex in January 2022, it is of interest to know if the usefulness of the MAG data is preserved or even improved in OpenAlex. To this end, we compared metadata that are relevant for bibliometric analyses (in particular field and time normalization of citations) of MAG and OpenAlex: - the coverage of documents over the years, - the agreement of bibliographic data, - the numbers of references of each document, - the kind and distribution of document types, - the distribution and relation of subject classifications.
