Data Sources and Citation Metrics
The 5th edition of the Research.com Best Chemistry Scientists in Korea Ranking is primarily based on bibliometric data collected from leading academic databases, chiefly OpenAlex and CrossRef, supplemented by multiple other reputable data sources. The bibliometric data used to devise citation-based metrics for this ranking were collected as of January 12, 2026. A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a metric that considers only the papers and associated citation metrics relevant to the examined discipline of Chemistry. This approach ensures a focused assessment of scholarly impact that pertains specifically to each researcher’s contributions within Chemistry.
Scope of Research and Selection Criteria
The ranking scrutinized a total of 279,971 scientist profiles identified across a broad variety of bibliometric sources encompassing all disciplines. Within the field of Chemistry specifically, 349 scientists were examined. To qualify for inclusion in the ranking, candidates were required to have a D-index of at least 40, with a majority of their tier publications firmly situated in the area of Chemistry. Additionally, scientists’ awards and notable achievements in the field of Chemistry were carefully considered as supplementary criteria.
The threshold for the D-index is adjusted in increments of 10 in accordance with the estimated total number of scholars within each discipline. This method balances inclusivity with rigor, ensuring that the top 1% of leading scholars in every field are accurately represented in the list. Furthermore, eligible scientists must demonstrate coherence between their general H-index and their D-index, with a proximity of 30% or less, thereby highlighting consistent scholarly influence both broadly and within the discipline.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly contribution, the researchers behind this ranking undertook rigorous manual verification of all scientist profiles. Each profile was cross-correlated against publications indexed in a wide spectrum of trustworthy academic sources to confirm accuracy and relevance. While the number of papers published in prominent journals and major conference proceedings does not directly affect a researcher's ranking position, it remains a valuable secondary indicator of a scientist’s contribution to research in Chemistry.
The final ranking positions are established using each researcher’s D-index derived from data aggregated primarily from OpenAlex and CrossRef, which are widely regarded as the most prominent and reliable bibliometric databases available to the research community.
