A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only papers and citations relevant to the specific discipline under examination—in this case, Earth Science. This approach ensures that the ranking accurately reflects contributions within the designated field of study, rather than general research impact.
Scope of Research and Criteria for Inclusion
The ranking methodology involved the analysis of 279,971 scientist profiles identified across a diverse range of bibliometric sources, encompassing all academic disciplines. Among these profiles, 24 scientists specializing specifically in Earth Science were examined in detail.
To qualify for inclusion in the ranking, a scientist’s D-index in Earth Science had to be a minimum of 30, with the majority of their tier publications clearly situated within this disciplinary domain. In addition to bibliometric metrics, scientists’ awards and recognized achievements within Earth Science were also factored into the assessment process.
The D-index threshold is dynamically set in increments of 10 relative to the estimated population of scholars within each discipline. This calibrated thresholding not only ensures the inclusion of the top 1% of leading researchers but also maintains rigorous standards tailored to the size of the disciplinary community. Furthermore, to ensure disciplinary focus, a scientist’s general H-index and their Earth Science-focused D-index were required to differ by no more than 30%.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot comprehensively capture the impact and quality of scholarly work, the researchers behind this ranking have conducted extensive manual verification of all scientist profiles. This process involved cross-correlating authorship and publication information against a broad spectrum of trustworthy sources to verify accuracy.
While the position in the Research.com ranking is driven solely by the D-index computed from OpenAlex and CrossRef data, the number of papers published in prominent peer-reviewed journals and conference proceedings serves as an important secondary indicator of a scientist’s contributions within their field. This auxiliary information, although not directly influencing rankings, complements the quantitative metrics by providing qualitative context regarding research dissemination and visibility.
