Abstract:
- Background. Scholarly documents referenced on Wikipedia play important roles in improving the quality of Wikipedia articles, and the references using DOI links are desirable for permanent access and correct identification. However, few studies have conducted long-term observation and analysis of the addition of DOI links for scholarly references on Wikipedia.
- Objectives. The study aims to clarify the long-term trends in the scholarly references on the English and Japanese Wikipedia from 2015 to 2023 using DOI links and associated Wikipedia articles.
- Methods. We extracted DOI links and Wikipedia articles containing them from Wikipedia dump files. Additionally, we obtained DOI Registration Agency (RA), Crossref metadata, and Essential Science Indicators categories, integrating them accordingly. We investigated (1) the statistics of DOI links and associated Wikipedia articles, (2) the difference and product sets from Wikipedias, (3) the top contents highly referenced on each Wikipedia, and (4) distributions of the DOI registration years/published years on DOI links newly added to English and Japanese Wikipedia.
- Results. (1) The diversities of RAs for DOI links increased in both Wikipedia from 2015 to 2023. (2) DOI links referenced in both Wikipedias increased five times from 2015 to 2023. Notably, unique DOI links referenced on Japanese Wikipedia (not overlapping with English Wikipedia) increased ten times. (3) DataCite DOIs have emerged among the top five contents in English and Japanese Wikipedia as of 2023. Three of the top five contents in Japanese Wikipedia were JaLC DOIs, all written in Japanese. (4) For DOI links added after 2015, most references in both Wikipedia point to scholarly articles published before 2015.
- Contributions. We clarified the long-term progress of adding DOI links as scholarly references on English and Japanese Wikipedia from 2015 to 2023. The findings of this study contribute to understanding the characteristics of DOI links referenced on Wikipedia and the trend of activities related to scholarly content on Wikipedia communities, as well as applications to Altmetrics studies.
