The 9th edition of Research.com ranking of the best researchers in the
discipline of Computer Science relies os data
derived from various data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
gathered on 21-12-2022. Position in the ranking is based on a
scholar’s D-index (Discipline H-index), which
takes into account only publications and citation
metrics for an examined discipline.
The scope of our Computer Science research
Research.com’s best scientists ranking is a reliable lineup of leading researchers from the discipline of Computer Science, based on a thorough analysis of 166,880 researchers determined from various bibliometric data sources. For the field of Computer Science, more than 14402 scholars were investigated.
What is D-index inclusion threshold for Computer Science
The D-index threshold for accepting a scholar to be evaluated is established at 30 if the majority of of their publications are in the discipline of Computer Science. The inclusion requirements for scientists to be considered into the ranking of top scientists are based on the D-index, ratio of the publications made within the specific discipline as well as the awards and achievements of the researchers. The D-index threshold for considering top scientists is set as an increment of 10 depending on the overall number of researchers estimated for each discipline whilst making sure that the top 1% of leading researchers are added into the ranking. We estimate a proximity of 30% or less between a scientist’s general H-index and their D-index.
Additional verification rules
As our leading goal is to make sure that only actual researchers are listed in the ranking we believe that numbers are never meant to be a complete tool to quantify the work of scientists. Because of that we manually check every profile and cross-correlate it against publications in a varied range of trustworthy sources. Even though it’s not a element impacting a scientist’s position in our ranking, the amount of documents published in well-known journals and conference proceedings should be a credible secondary indication of their contribution to research in a given field of study. Position in the ranking is determined by every researcher’s D-index according to information gathered from OpenAlex and CrossRef, which are the most prominent and well-known bibliometric databases of this kind available to the research community. A thorough overview of our research procedures can be found on our methodology page.
Our objective is to motivate scientists, businessmen and decision-makers around the world to investigate where leading experts are heading and to give an opportunity for the entire research community to get to know who the leading experts in specific fields of research, in various countries, or even within research institutions are.
