Twenty years of Wikipedia in scholarly publications: a bibliometric network analysis of the thematic and citation landscape | SpringerLink

Abstract:  Wikipedia has grown to be the biggest online encyclopedia in terms of comprehensiveness, reach and coverage. However, although different websites and social network platforms have received considerable academic attention, Wikipedia has largely gone unnoticed. In this study, we fill this research gap by investigating how Wikipedia is used in scholarly publications since its launch in 2001. More specifically, we review and analyze the intellectual structure of Wikipedia’s scholarly publications based on 3790 Web of Science core collection documents written by 10,636 authors from 100 countries over two decades (2001–2021). Results show that the most influential outlets publishing Wikipedia research include journals such as Plos one, Nucleic Acids Research, the Journal of the Association for Information Science and Technology, the Journal of the American Society for Information Science and Technology, IEEE Access, and Information Processing and Management. Results also show that the author collaboration network is very sparsely connected, indicating the absence of close collaboration among the authors in the field. Furthermore, results reveal that the Wikipedia research institutions’ collaboration network reflects a North–South divide as very limited cooperation occurs between developed and developing countries’ institutions. Finally, the multiple correspondence analysis applied to obtain the Wikipedia research conceptual map reveals the breadth, diversity, and intellectual thrust of the Wikipedia’s scholarly publications. Our analysis has far-reaching implications for aspiring researchers interested in Wikipedia research as we retrospectively trace the evolution in research output over the last two decades, establish linkages between the authors and articles, and reveal trending topics/hotspots within the broad theme of Wikipedia research.
