Description

Objective: With the recent transformation of the eScience Portal for Librarians into the new, nation-wide NNLM RD3: Resources for Data-Driven Discovery site, the eScience Thesaurus was updated and renamed the Data Thesaurus. A literature review of library-focused eScience articles was performed to update the term pages of the Thesaurus. Using term mapping, what can these articles tell us about the trends in eScience research?

Methods: A comprehensive literature review was performed October 2016 as part of the eScience Thesaurus update. Using the search strategy and resources listed by Kevin et al. (2013) to create the Thesaurus and limiting the date range of the articles from 2013-2016, 714 articles were found and citation information was imported into Mendeley. The citation information was then imported into VOSviewer for visualization and analysis.

Results: The central term within the citation information is data, being both the most prevalent and spread across all years. Terms such as information, data curation, and institutional repository appear more often in earlier papers. More recent publications have a higher prevalence of terms such as big data, data quality, and open data.

Conclusion: Using term mapping, one can visualize the shift in the publishing trends of a field, even in a small field such as library-focused eScience research, but a larger dataset with a larger date range is recommended for a better understanding of trends. The updated Thesaurus will be available at https://nnlm.gov/data/data-thesaurus coming April 2018.
