Abstract

Unlike traditional proprietary data sources like Scopus and Web of Science (WoS), OpenAlex emphasizes its comprehensive coverage, particularly highlighting its inclusion of the humanities, non-English languages, and research from the Global South. Strengthening diversity and inclusivity in science is crucial for ethical and practical reasons. This paper analyses OpenAlex's coverage and metadata availability of African-based publications. For this purpose, we compare OpenAlex with Scopus, WoS, and African Journals Online (AJOL). We first compare the coverage of African research publications in OpenAlex against that of WoS, Scopus, and AJOL. We then assess and compare the available metadata for OpenAlex, Scopus, and WoS publications. Our analysis shows that OpenAlex offers the most extensive publication coverage. In terms of metadata, OpenAlex offers a high coverage of publication and author information. It performs worse regarding affiliations, references, and funder information. Importantly, our results also show that metadata availability in OpenAlex is better for publications that are also indexed in Scopus or WoS.

OpenAlex 中非洲出版物的覆盖面和元数据可用性：比较分析

与 Scopus 和 Web of Science（WoS）等传统的专有数据源不同，OpenAlex 强调其覆盖面的全面性，尤其突出其对人文学科、非英语语言和全球南部研究的收录。出于伦理和现实的原因，加强科学的多样性和包容性至关重要。为此，我们将 OpenAlex 与 Scopus、WoS 和 African JournalsOnline (AJOL) 进行了比较。我们首先将 OpenAlex 中非洲研究出版物的覆盖范围与 WoS、Scopus 和 AJOL 的覆盖范围进行了比较。然后，我们对 OpenAlex、Scopus 和 WoS 出版物的可用元数据进行了评估和比较。我们的分析表明，OpenAlex 的出版物覆盖面最广。在元数据方面，OpenAlex 的出版物和作者信息覆盖率较高。它在从属关系、参考文献和资助者信息方面的表现较差。重要的是，我们的结果还表明，对于同时被 Scopus 或 WoS 索引的出版物，OpenAlex 的元数据可用性更好。
