Understanding discrepancies in the coverage of OpenAlex: the case of China.
Citations indexes play a crucial role for understanding how science is produced,disseminated, and used. However, these databases often face a critical trade-off:those offering extensive and high-quality coverage are typically proprietary,whereas publicly accessible datasets frequently exhibit fragmented coverage andinconsistent data quality. OpenAlex was developed to address this challenge, pro-viding a freely available database with broad open […] Lire la suite
Examining the geographic and linguistic coverage of gold and diamond open access journals in OpenAlex, Scopus, and Web of Science.
Diamond open access (OA) journals are a publishing model that is free for both authors and readers, but their lack of indexing in major bibliographic databases compared to gold journals presents challenges in assessing their uptake. Furthermore, the characteristics of diamond journals, such as language and country of publication, have often been used to support […] Lire la suite
Scholarly publishing’s hidden diversity: How exclusive databases sustain the oligopoly of academic publishers
Abstract Global scholarly publishing has been dominated by a small number of publishers for several decades. This paper revisits the data on corporate control of scholarly publishing by analyzing the relative shares of scholarly journals and articles published by the major publishers and the “long tail” of smaller, independent publishers, using Dimensions and Web of […] Lire la suite
Shine bright like a diamond: A bibliometric analysis of diamond Open Access journals and their coverage in Web of Science, Scopus and OpenAlex
The Budapest Open Access Initiative (2002) advocated for a new generation of journals that would rely on alternative sources of funding to support Open Access (OA) dissemination. Author fees or article processing charges (APCs) have now become one of the most common sources of funding for OA journals. These APCs dominate the public discourse surrounding […] Lire la suite
Examining the quality of the corresponding authorship field in Web of Science and Scopus
Authorship is associated with scientific capital and prestige, and corresponding authorship is used in evaluation as a proxy for scientific status. However, there are no empirical analyses on the validity of the corresponding authorship metadata in bibliometric databases. This paper looks at differences in the corresponding authorship metadata in Web of Science (WoS) and Scopus […] Lire la suite
The decrease in uncited articles and its effect on the concentration of citations
Empirical evidence demonstrates that citations received by scholarly publications follow a pattern of preferential attachment, resulting in a power-law distribution. Such asymmetry has sparked significant debate regarding the use of citations for research evaluation. However, a consensus has yet to be established concerning the historical trends in citation concentration. Are citations becoming more concentrated in […] Lire la suite
Langues de diffusion des connaissances : quelle place reste-t-il pour le français?
La croissance des évaluations basées sur le nombre de publications savantes dans bon nombre de pays1 , jumelée à la démocratisation des technologies numériques et au contrôle de l’édition savante par quelques compagnies privées2 , est associée à l’établissement d’une culture de la publication où les chercheur-se-s publient de plus en plus3 . Cette tendance […] Lire la suite
