Data Sources and Metrics
The 5th edition of the Research.com Best Earth Science Scientists in Kyrgyzstan Ranking was developed using comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, along with multiple other reputable data repositories. These sources offer extensive citation and publication records, enabling a robust and transparent evaluation of scholarly output. The citation-based metrics that underpin this ranking were collected on January 12, 2026, ensuring up-to-date and relevant data for analysis.
A scientist's position in this ranking is determined by their D-index (Discipline H-index), a refined metric that calculates impact exclusively within the examined discipline — Earth Science in this case. This approach ensures that the evaluation reflects contributions specifically relevant to the field rather than general academic productivity.
Scope of Research and Eligibility
The ranking is based on an extensive review of 279,971 scientist profiles drawn from diverse bibliometric databases covering all scientific disciplines. Within this broad dataset, 1 scientist specifically identified with Earth Science in Kyrgyzstan met the eligibility criteria.
To qualify for inclusion, scientists were required to have a D-index of at least 30, reflecting significant scholarly influence in Earth Science. Additionally, the majority of their tier publications had to be concentrated within this discipline. Consideration was also given to the scientists’ awards and achievements in the Earth Science field to further substantiate their standing.
The threshold for the D-index varies by discipline in increments of 10, calibrated according to the total number of scholars identified per field. This methodology guarantees the inclusion of the top 1% of leading scholars while maintaining discipline-specific rigor. Furthermore, a scientist's general H-index and D-index must not differ by more than 30%, reinforcing discipline relevance and focus in their research output.
Verification and Evaluation Practices
Recognizing that raw bibliometric data should not serve as an absolute or sole measure of academic excellence, the Research.com team conducted meticulous manual verification of all scientist profiles. This process involved cross-referencing publications against a wide array of trustworthy sources to validate the accuracy and relevance of the information presented.
While the primary ranking factor remains the D-index derived from OpenAlex and CrossRef data, the count of publications in high-impact journals and leading conferences was also reviewed as a valuable secondary indicator of a scientist’s contribution to Earth Science. These additional insights provide complementary context but do not influence the absolute position within the ranking.
The ranking methodology leverages OpenAlex and CrossRef due to their prominence and comprehensive coverage in bibliometric data, serving the global research community with reliable and transparent scholarly metrics.
