A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a precise measure that only includes papers and citation data relevant to the examined discipline—Plant Science and Agronomy. This careful focus ensures that ranking outcomes accurately reflect a researcher’s impact and contributions within their specific field.
Scope of Research and Qualification Criteria
The ranking process began with the examination of 279,971 scientist profiles identified from an array of high-quality bibliometric data sources spanning all scientific disciplines. Within this extensive pool, only 2 scientists from Plant Science and Agronomy in the Syrian Arab Republic qualified for consideration based on the established criteria.
- To qualify for the ranking, a scientist’s D-index had to be at least 30, signifying a substantial and impactful research output within Plant Science and Agronomy.
- A majority of the scholar’s tier publications were required to be specifically concentrated in the field of Plant Science and Agronomy, ensuring genuine disciplinary relevance.
- Scientist awards and achievements within Plant Science and Agronomy were also taken into account as a qualitative factor reinforcing a candidate’s standing in the field.
The threshold for the D-index is established as increments of 10, calibrated in accordance with the estimated total number of scholars in each discipline, while guaranteeing that at least the top 1% of leading researchers are incorporated into the ranking. Furthermore, to maintain disciplinary fidelity, the allowed proximity between a scientist’s general H-index and their D-index is capped at 30% or less.
Verification Practices and Data Integrity
Recognizing that raw bibliometric data alone cannot serve as an absolute benchmark for a scholar’s output, the Research.com team conducted manual verification of all scientist profiles involved in this ranking. Additionally, each profile was cross-correlated against publications indexed in a broad range of trusted and reputable sources to affirm accuracy and relevance.
While the number of papers published in prominent journals and conference proceedings does not directly affect a researcher’s position in the ranking, it remains a valuable secondary indicator of a scientist's contribution to their discipline.
The final determination of rank positions was made using each researcher’s D-index, calculated from robust, curated information obtained from the established bibliometric repositories OpenAlex and CrossRef. These databases are among the most prominent and respected for scientific citation data, providing the research community with reliable metrics.
