Data Sources and Metrics
The 5th edition of the Research.com Best Social Sciences and Humanities Scientists in South Africa Ranking is primarily grounded in data gathered from reputable bibliometric databases, notably OpenAlex and CrossRef, supplemented by multiple other trusted sources. On 2026-01-12, bibliometric data essential for formulating the citation-based metrics underlying this ranking were collected. Each scientist’s position is determined by their Discipline H-index (D-index), a refined bibliometric indicator that exclusively accounts for publications and citations within the examined discipline, thereby providing a targeted measure of scholarly impact in Social Sciences and Humanities.
Scope of Research and Selection Criteria
The ranking draws from an extensive pool of 279,971 scientist profiles identified across various bibliometric sources encompassing all fields of study. From this broad spectrum, 61 scientists specifically affiliated with Social Sciences and Humanities were rigorously examined. To qualify for inclusion, a scientist’s D-index must be a minimum of 30, with the majority of their tier publications situated within Social Sciences and Humanities. In addition, awards and distinguished achievements within these fields were considered to complement the bibliometric criteria.
The D-index threshold is dynamically determined by increments of 10 based on the estimated total number of scholars in each discipline, carefully calibrated to ensure that the top 1% of leading scholars in the field are represented in the ranking. Furthermore, eligibility requires a close alignment between a scientist’s general H-index and their D-index, with a proximity threshold set at 30% or less, underscoring consistency between overall impact and disciplinary focus.
Verification and Validation Processes
Recognizing that raw bibliometric data alone cannot definitively evaluate scholarly contributions, the Research.com team undertook comprehensive manual verification of all scientist profiles. This verification included cross-correlation of publication records against a wide range of reliable and authoritative sources to ensure accuracy and authenticity.
Although the number of papers published in prominent journals and conference proceedings does not directly influence the ranking position, it serves as an important secondary indicator of a researcher’s contribution to Social Sciences and Humanities. The ranking itself is based on the D-index metric, derived from data collected through OpenAlex and CrossRef, two of the most well-established bibliometric databases accessible to the global research community.
