A scientist’s position within the ranking is determined based on their D-index (Discipline H-index), a refined metric that specifically measures research impact by including only those papers and citation counts relevant to the examined discipline of Engineering and Technology. This targeted approach enhances the accuracy and discipline specificity of the rankings.
Scope of Research and Eligibility Criteria
The ranking evaluates 279,971 scientist profiles identified from a diverse array of bibliometric databases spanning all academic disciplines. Within this broad dataset, a focused review was conducted on 35 scientists specializing in Engineering and Technology in New Zealand.
To qualify for inclusion in this ranking, researchers were required to have a D-index of at least 30 with a majority of their tier publications centered in Engineering and Technology. In addition to bibliometric performance, scientists’ awards and professional recognitions within the Engineering and Technology domain were also taken into account to substantiate their influence and contributions.
The threshold for the D-index is dynamically tailored in increments of 10 based on the estimated total number of scholars in each discipline. This methodology ensures that the ranking consistently incorporates the top 1% of leading experts within each field. Additionally, a close alignment is maintained between a scientist’s general H-index and their discipline-specific D-index, with the permitted proximity set to 30% or less, reinforcing the focus on subject-matter expertise.
Verification and Validation Process
Recognizing that raw bibliometric data alone cannot fully capture the quality or influence of scholarly contributions, the Research.com team undertook meticulous manual verification of all scientist profiles. This process involved cross-correlation of publication records from a wide range of authoritative and trustworthy sources to confirm accuracy and relevance.
Although not factored directly into the ranking position, the number of publications in prominent journals and esteemed conference proceedings is considered a valuable complementary indicator of a scientist’s impact within their field.
Ultimately, each researcher’s standing in the ranking is established using their D-index metrics derived from OpenAlex and CrossRef, which remain the most prominent and reliable bibliometric databases accessible to the global research community.
