A key metric utilized in determining each scientist’s position within the ranking is the D-index (Discipline H-index). Unlike a general H-index, the D-index is discipline-specific, incorporating only those publications and citations that pertain to the examined field—in this case, Animal Science and Veterinary. This focused approach allows for a specialized evaluation of scholarly impact within the discipline, reflecting depth and relevance in the designated area of study.
Scope and Qualification Criteria
The ranking process involved a thorough review of 279,971 scientist profiles spanning all disciplines derived from diverse bibliometric sources. Within this extensive pool, 5 scientists were identified and evaluated specifically under the domain of Animal Science and Veterinary. To qualify for inclusion, a scientist’s D-index needed to meet or exceed the threshold of 20, and a majority of their tier publications were required to emphasize research in Animal Science and Veterinary. Additionally, recognition of scientists’ awards and achievements within the discipline contributed to the qualification criteria.
The threshold for the D-index is dynamically set in increments of 10 according to the total estimated number of scholars in each discipline, with the primary intention of incorporating the top 1% of leading researchers in the field. An important quality control measure ensures that the proximity between a scientist’s overall H-index and their D-index remains within 30% or less, safeguarding against disproportionate generalist profiles being inappropriately ranked within a specialized discipline.
Verification Practices and Methodology Transparency
We recognize that bibliometric raw data alone cannot serve as an absolute measure of scholarly output and impact. Therefore, all scientist profiles included in the ranking underwent meticulous manual verification processes. These profiles were cross-correlated with publications extracted from a broad spectrum of trustworthy and authoritative sources to confirm accuracy and relevance.
While the number of papers published in prominent journals and conference proceedings does not directly influence the ranking position, it remains a valuable secondary indicator of a scientist’s contribution to their specific research area. The core ranking methodology centers on the rigorously calculated D-index derived from OpenAlex and CrossRef databases, which are widely regarded for their comprehensive and robust bibliometric data coverage available to the research community.
