An institution’s position within the ranking is determined by the sum of the D-indexes (Discipline H-index, which covers only publications and citation data specific to the discipline) of all scholars affiliated with that institution, provided their primary publication area is Political Science. This ensures an accurate reflection of research excellence tied directly to Political Science, rather than overall scientific output.
Scope of Research Considered for the Ranking
A total of 279,971 scientist profiles, identified from a variety of bibliometric sources, were examined for inclusion in the rankings. Of these, 2,158 scientists whose primary research area is Political Science were analyzed in detail. To ensure rigorous eligibility, scientists were required to meet a minimum D-index threshold of 20, with the majority of their significant publications situated within Political Science.
Other qualitative factors were also considered, including scientists’ awards and achievements in Political Science. The D-index threshold for identifying top researchers increases in increments of 10, proportionate to the number of scholars estimated for each discipline, and is structured to guarantee that the top 1% of leading scholars are always represented. For inclusion, a scientist’s general H-index must be no more than 30% higher than their D-index, ensuring true disciplinary expertise. Additionally, notable achievements and distinctions in Political Science contributed to individual evaluations.
Verification Practices and Data Validation
Recognizing that bibliometric data alone cannot fully capture research quality, the Research.com team took additional verification steps. Every scientist profile within the ranking underwent manual verification and was rigorously cross-checked against publications in numerous reputable sources to ensure accuracy and authenticity.
While the count of papers in prominent journals and conference proceedings is not a direct ranking factor, it is acknowledged as a valuable secondary indicator of a scientist’s impact. The central ranking metric remains the H-index derived for each researcher from OpenAlex and CrossRef, the research community’s most trusted bibliometric resources.
