Data Sources and Metrics Used in the 3rd Edition of Research.com Best Universities in Iran, Islamic Republic Of Ranking
The 3rd edition of the Research.com Best Universities in Iran, Islamic Republic Of Ranking is rooted in the careful integration of multiple reputable data sources. The primary bibliometric sources informing this ranking are OpenAlex and CrossRef, complemented by several additional data repositories to ensure comprehensive coverage. The bibliometric data that supports the citation-based evaluation metrics for this edition were systematically collected as of 2024-11-27.
University positions within the ranking are determined by aggregating the D-indexes (Discipline H-index) of all affiliated researchers who are featured in the ranking. The D-index is computed using exclusively publication and citation data pertinent to each specific scientific discipline. Importantly, the ranking takes into account scholars from all major research domains affiliated with each institution, providing a holistic and multi-disciplinary measure of institutional research strength.
Scope of the Research Underpinning the Ranking
The scope of the ranking is comprehensive: a total of 279,971 scientist profiles were rigorously analyzed, sourced from a variety of leading bibliometric databases. These researchers span all major scientific disciplines, ensuring the ranking accurately reflects the breadth of academic research in Iran. To maintain a high standard of research excellence, only scientists with a qualifying D-index threshold of at least 20 were included. In addition, distinguished awards and notable achievements in each scientist’s area of work were taken into consideration as supplemental signals of research impact and distinction.
Data Verification and Validation Procedures
Recognizing the limitations inherent to raw bibliometric data, the Research.com team undertook an exhaustive manual verification process for every scientist profile included in the ranking. All profiles were cross-referenced and validated against publications from an array of trusted sources to ensure both accuracy and integrity. Although the number of papers published in leading journals and reputable conferences does not directly determine a scholar’s position in the ranking, such metrics are acknowledged as important indicators of a scientist’s contribution to their discipline.
The principal metric for assigning positions within the ranking is each scientist’s H-index, as sourced from OpenAlex and CrossRef — two of the most authoritative and widely recognized bibliometric databases available to the research community.
