A tale of two databases: the use of Web of Science and Scopus in academic papers
Web of Science and Scopus are two world-leading and competing citation databases. By using the Science Citation Index Expanded and Social Sciences Citation Index, this paper conducts a comparative, dynamic, and empirical study focusing on the use of Web of Science (WoS) and Scopus in academic papers published during 2004 and 2018. This brief communication reveals that although both Web of Science and Scopus are increasingly used in academic papers, Scopus as a new-comer is really challenging the dominating role of WoS. Researchers from more and more countries/regions and knowledge domains are involved in the use of these two databases. Even though the main producers of related papers are developed economies, some developing economies such as China, Brazil and Iran also act important roles but with different patterns in the use of these two databases. Both two databases are widely used in meta-analysis related studies especially for researchers in China. Health/medical science related domains and the traditional Information Science and Library Science field stand out in the use of citation databases.

Regional disparities in Web of Science and Scopus journal coverage
The two most important citation indexes used by the global science community contain marked regional disparities in their representation of academic journals. Existing work on the geographical coverage of Web of Science and Scopus citation indexes compared their coverage of journals in a small sample of ‘top’ countries. This paper offers the first regional analysis of journal representation in these two indexes across all eight UNESCO world regions, compared to the total number of active Ulrich’s directory academic journals in these regions. Journal lists from 239 countries/territories were collected from Ulrich’s periodical directory and analyzed by region. This enables a comparison of the regional distribution of journals within Web of Science (20,255 matched journals) and Scopus (23,348 matched journals) with those in Ulrich’s directory (83,429 journals). Journals published in Europe, Oceania and North America were more likely to be indexed in Scopus and Web of Science compared to other world regions. Journals published in sub-Saharan Africa were the most underrepresented and were four times less likely to be indexed than those published in Europe. The analysis also offers a quantitative breakdown of journal publication languages, highlighting how Scopus and Web of Science disproportionately index English language publications in all world regions. Finally, the analysis shows how field coverage by Web of Science and Scopus differs between the regions, with the Social Sciences and Humanities still under-represented, in comparison to Natural Sciences and Medical & Health Science.

The journal coverage of Web of Science, Scopus and Dimensions: A comparative analysis
Traditionally, Web of Science and Scopus have been the two most widely used databases for bibliometric analyses. However, during the last few years some new scholarly databases, such as Dimensions, have come up. Several previous studies have compared different databases, either through a direct comparison of article coverage or by comparing the citations across the databases. This article aims to present a comparative analysis of the journal coverage of the three databases (Web of Science, Scopus and Dimensions), with the objective to describe, understand and visualize the differences in them. The most recent master journal lists of the three databases is used for analysis. The results indicate that the databases have significantly different journal coverage, with the Web of Science being most selective and Dimensions being the most exhaustive. About 99.11% and 96.61% of the journals indexed in Web of Science are also indexed in Scopus and Dimensions, respectively. Scopus has 96.42% of its indexed journals also covered by Dimensions. Dimensions database has the most exhaustive journal coverage, with 82.22% more journals than Web of Science and 48.17% more journals than Scopus. This article also analysed the research outputs for 20 selected countries for the 2010–2018 period, as indexed in the three databases, and identified database-induced variations in research output volume, rank, global share and subject area composition for different countries. It is found that there are clearly visible variations in the research output from different countries in the three databases, along with differential coverage of different subject areas by the three databases. The analytical study provides an informative and practically useful picture of the journal coverage of Web of Science, Scopus and Dimensions databases.

Web of Science and Scopus language coverage
The evaluation of research outputs in the form of journal articles is important to help with monitoring performance and to allocate funds. Elsevier’s Scopus and Clarivate’s Web of Science (WoS) are the two main sources for identifying outputs. For non-English-speaking countries, it is especially important that most of the scientific activity evaluated is represented in the bibliometric database used. All documents published in Scopus and WoS during 2018 (6,094,079 documents) were therefore analysed and compared for their languages and research areas. The most comprehensive source for each language and research area were identified and some coverage problems have been found.

Identifying interdisciplinary topics and their evolution based on BERTopic
Interdisciplinary topic reflects the knowledge exchange and integration between different disciplines. Analyzing its evolutionary path is beneficial for interdisciplinary research in identifying potential cooperative research direction and promoting the cross-integration of different disciplines. However, current studies on the evolution of interdisciplinary topics mainly focus on identifying interdisciplinary topics at the macro level. More analysis of the evolution process of interdisciplinary topics at the micro level is still needed. This paper proposes a framework for interdisciplinary topic identification and evolutionary analysis based on BERTopic to bridge the gap. The framework consists of four steps: (1) Extract the topics from the dataset using the BERTopic model. (2) Filter out the invalid global topics and stage topics based on lexical distribution and further filter out the invalid stage topics based on topic correlation. (3) Identify interdisciplinary topics based on disciplinary diversity and disciplinary cohesion. (4) Analyze the interdisciplinary topic evolution by inspecting the intensity and content in the evolution, and visualize the evolution using Sankey diagrams. Finally, We conduct an empirical study on a dataset collected from the Web of Science (WoS) in Library & Information Science (LIS) to evaluate the validity of the framework. From the dataset, we have identified two distinct types of interdisciplinary topics in LIS. Our findings suggest that the growth points of LIS mainly exist in the interdisciplinary research topics. Additionally, our analysis reveals that more and more interdisciplinary knowledge needs to be integrated to solve more complex problems. Mature interdisciplinary topics mainly formed from the internal core knowledge in LIS stimulated by external disciplinary knowledge, while promising interdisciplinary topics are still at the stage of internalizing and absorbing the knowledge of other disciplines. The dataset, the code for implementing the algorithms, and the complete experiment results will be released on GitHub at:
