Data Sources and Citation Metrics
The 12th edition of the Research.com Best Computer Science Scientists in Iran Ranking is primarily based on extensive bibliometric data collected from leading databases, including OpenAlex and CrossRef, supplemented by multiple other reputable data sources. The citation-based metrics that form the foundation of this ranking were compiled on January 12, 2026, ensuring the inclusion of the most recent and comprehensive publication and citation records. A key metric utilized in establishing a scientist’s position in the ranking is the D-index (Discipline H-index), which specifically accounts for papers and citation metrics within the examined discipline, in this instance, Computer Science. This specialized index allows for a focused and accurate assessment of scientific impact within the relevant research area.
Scope of Research and Inclusion Criteria
For this ranking, a broad examination was conducted across 279,971 scientist profiles identified from a diverse array of bibliometric sources spanning all scientific disciplines. Within this extensive dataset, 24 scientists specializing in Computer Science were meticulously evaluated. To qualify for inclusion in the ranking, a scientist’s D-index had to reach a minimum threshold of 30, alongside the majority of their tier publications being in the domain of Computer Science. Furthermore, distinctions such as awards and notable achievements within the field were also factored into the evaluation.
The threshold for the D-index varies incrementally by 10, depending on the estimated total number of scholars within each discipline, thereby ensuring that the ranking reliably includes the top 1% of leading researchers. Additionally, the methodology requires that the proximity between a scientist’s general H-index and their discipline-specific D-index does not exceed 30%, maintaining consistency and relevance in the assessment of disciplinary impact.
Verification Practices and Ranking Methodology
The Research.com team recognizes that raw bibliometric data alone cannot fully capture the quality and impact of scholarly contributions. To address this, all scientist profiles underwent thorough manual verification and were cross-correlated against publications listed in a wide spectrum of trustworthy sources. While the number of publications in prestigious journals and conference proceedings does not directly influence a researcher’s ranking position, it serves as a valuable secondary signal of their contribution to their specific scientific area.
The final ranking positions are determined based on each researcher’s D-index, calculated from data aggregated through OpenAlex and CrossRef — the most prominent and widely recognized bibliometric databases accessible to the global research community.
