The core of the ranking methodology focuses on a sum of D-indexes (Discipline H-index) of all ranked scholars affiliated with a given institution whose primary area of publication is in Political Science. The D-index is calculated by considering only those publications and citation data pertinent to the examined discipline, ensuring discipline-specific accuracy and comparability across institutions.
Scope of Research and Selection Criteria
To ensure a rigorous and representative assessment, a total of 279,971 scientist profiles were examined across an extensive spectrum of bibliometric data sources. Out of this comprehensive pool, 2,158 scientists specializing in Political Science were specifically analyzed.
To maintain the highest standards, a qualifying D-index threshold of 20 was established for each scientist, with the majority of their impactful publications required to be in the area of Political Science. Additionally, scientists' awards and notable achievements within the discipline were incorporated as significant qualitative metrics. Selection of top researchers incorporated an incremented D-index threshold (in steps of 10) depending on the discipline’s scholar population, while guaranteeing that the top 1% of leading scholars are reflected in the list.
Further granularity is provided by ensuring that proximity between a scientist’s general H-index and their D-index does not exceed 30%, thus maintaining discipline specificity. Consideration of scientists’ distinguished awards and accomplishments in their field supplemented the quantitative metrics, ensuring a holistic evaluation process.
Verification Practices and Methodological Transparency
The Research.com team acknowledges that raw bibliometric data alone are insufficient as absolute evaluative tools for scholarly output. Consequently, all scientist profiles underwent manual verification and comprehensive cross-correlation against a wide range of reputable publication sources.
While the number of papers published in leading journals and conference proceedings does not directly influence a researcher's ranking position on Research.com, it remains a vital secondary indicator of substantive research contributions within Political Science.
Institutions’ positions in the ranking are determined through aggregation of eligible scholars’ H-indexes, derived from OpenAlex and CrossRef — currently the most authoritative and widely recognized sources for this type of bibliometric data within the academic community.
