A researcher’s position within the ranking is determined by their Discipline H-index (D-index), a refined variant of the traditional H-index that exclusively considers papers and citation metrics within the examined discipline—in this case, Chemistry. This discipline-specific focus ensures the metric accurately reflects contributions and impact within the relevant field.
Scope of Research and Inclusion Criteria
To ensure a rigorous and meaningful evaluation, 279,971 scientist profiles were analyzed across all scientific disciplines from a broad spectrum of bibliometric data sources. Specifically, 1,731 scientist profiles identified as working in Chemistry were considered for inclusion in this ranking.
In order to qualify for the Best Chemistry Scientists in Latvia Ranking, a scientist’s D-index must be at least 40, signaling a high level of sustained scholarly impact within Chemistry. Additionally, the majority of the researcher’s tier publications are required to be explicitly within the area of Chemistry. Recognition through awards and achievements specific to Chemistry was also taken into account to further contextualize scholarly influence and excellence.
The threshold for the D-index is dynamically set in increments of 10, proportionate to the estimated total number of scholars in each discipline, thereby guaranteeing inclusion of the top 1% of leading researchers. To maintain intellectual rigor, scientists included typically exhibit a proximity of 30% or less between their general H-index and D-index, ensuring their impact is strongly grounded within the discipline.
Additional Verification Practices
The creators of this ranking acknowledge that raw bibliometric data alone cannot fully capture the nuanced output and quality of scholarly contributions. Accordingly, all scientist profiles underwent meticulous manual verification and were cross-correlated against publications indexed in a diverse array of trustworthy sources.
Although the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it remains an important secondary signal of a scientist’s active contribution and leadership in their field.
Overall, a researcher's position is established utilizing their D-index as derived from data compiled from OpenAlex and CrossRef, both of which are widely recognized as authoritative bibliometric databases.
