Institutional positioning in the ranking is determined by aggregating the D-indexes (Discipline H-index) of all scholars affiliated with a given institution, whose primary publication area lies within Social Sciences and Humanities. It is crucial to note that the D-index exclusively accounts for publications and citations within the designated discipline, ensuring a focused and accurate evaluation of each researcher’s impact in the field.
Scope of Research Considered
The current edition of the ranking thoroughly examined 279,971 scientist profiles identified from a variety of bibliometric sources. From these, 17,050 scientists specializing in Social Sciences and Humanities were closely analyzed. A qualifying D-index threshold of 30 was set for each scientist, coupled with the requirement that a majority of their publications reside within Social Sciences and Humanities.
The evaluation process also considered each scientist’s noteworthy awards and achievements in the field. For the identification of top researchers, the D-index threshold was incremented by 10, depending on the total number of scholars estimated for individual disciplines, ensuring that the top 1% of leading experts were incorporated. To maintain discipline-specific relevance, a proximity of 30% or less between a scientist’s general H-index and their D-index was enforced. Recognition in the form of awards and outstanding career achievements further contributed to each scientist’s qualification.
Verification Practices and Data Integrity
Researchers developing the ranking understand that raw bibliometric data alone does not fully encapsulate the breadth of a scientist’s contributions. Hence, all scientist profiles underwent manual verification and were cross-correlated against publication records found in a comprehensive range of trusted sources. Although the volume of papers published in leading journals and high-profile conference proceedings does not directly influence a researcher’s ranking position, it is nevertheless regarded as a valuable secondary indicator of significant contributions to their field.
Ranking positions are established using each researcher’s H-index, as reported by OpenAlex and CrossRef—databases recognized as the benchmark within the global research community for bibliometric information.
