Data Sources and Metrics Used in the 4th Edition of Research.com Best Ecology and Evolution Universities in Norway Ranking
The 4th edition of the Research.com Best Ecology and Evolution Universities in Norway Ranking utilizes a comprehensive suite of bibliometric data sources to ensure accuracy and thoroughness. The primary bibliometric datasets employed are OpenAlex and CrossRef, complemented by several other verified data sources. The citation-based metrics upon which this ranking rests were meticulously assembled as of 2024-11-27. Each institution’s ranking position is determined by the sum of D-indexes (Discipline H-index) of all considered scholars affiliated with the university, where Ecology and Evolution is their primary research domain. The D-index captures only the publications and citations that pertain specifically to Ecology and Evolution, thereby ensuring precision in evaluating scholarly contribution within the examined discipline.
Scope of Research Considered for the Ranking
To construct this ranking, the profiles of 279,971 scientists sourced from a diversity of bibliometric repositories were examined, of whom 28,170 scientists are primarily active in Ecology and Evolution. To qualify for analysis, a scientist needed a minimum D-index of 30, and the preponderance of their significant publications had to be within Ecology and Evolution. Additionally, scientists’ awards and achievements in the field were incorporated as contributing factors. The criteria for inclusion as a leading researcher adapt to discipline size: the D-index requirement increases in increments of 10 according to the number of active scholars in a field, always ensuring that the top 1% of global experts are present in the ranking. Additionally, for robust subject relevance, the difference between a scientist’s overall H-index and ecology/evolution-specific D-index could not exceed 30%. Scholars' accolades and distinct contributions were also considered, ensuring that excellence in impact and recognition is reflected.
Verification Practices and Data Integrity
Research.com recognizes that raw bibliometric data is not, by itself, a definitive measure of scholarly achievement. Therefore, every scientist profile in the ranking underwent rigorous manual verification. Analysts cross-referenced each profile against publications listed in a broad spectrum of respected sources, adding a vital layer of scrutiny. While the count of papers in high-profile journals and conference proceedings does not influence a scholar’s rank directly, it serves as a valuable secondary indicator of sustained research activity and output excellence. Final positions are calculated based on H-indexes derived from OpenAlex and CrossRef, which are renowned for their comprehensive and reliable coverage of research metrics. This dual-sourcing enhances reproducibility and transparency. For an in-depth understanding of the metrics and methodology applied, please visit our methodology page.
