Best Computer Science Scientists in Brazil

The 9th edition of ranking of the best scholars in the arena of Computer Science is based on data combined from multiple data sources including OpenAlex and CrossRef. The bibliometric data for estimating the citation-based metrics were collected on 21-12-2022. Position in the ranking is based on a researcher’s D-index (Discipline H-index), which only includes papers and citation values for an examined discipline.

The focus of our Computer Science research’s best scientists ranking is a credible lineup of leading researchers from the area of Computer Science, created using a detailed analysis of 166,880 scientists identified from a variety of bibliometric data sources. For the discipline of Computer Science, more than 14402 scholars were analysed.

What is D-index approval threshold for Computer Science
The D-index threshold for including a scientist to be examined is placed at 30 if the majority of of their publications are in the area of Computer Science. The acceptance criteria for scientists to be considered into the ranking of top researchers are based on the D-index, proportion of the contributions made within the given area as well as the awards and achievements of the researchers. The D-index threshold for including top scholars is set as an increment of 10 depending on the total number of scientists estimated for each area od study whilst guaranteeing that the top 1% of leading scholars are added into the ranking. We estimate a proximity of 30% or less between a scholar’s general H-index and their D-index.

Extra verification rules
Because our leading goal is to make sure that only genuine scientists are mentioned in our ranking we are aware that raw data are never supposed to be a complete tool to quantify the output of scholars. Because of that we manually check each profile and cross-correlate it against publications in a wide range of trustworthy sources. While it’s not a metric contributing to a scholar’s position in ranking, the amount of documents published in well-known journals and conference proceedings should constitute a reliable secondary implication of their contribution to research in a specific field of study. Position in the ranking is determined by each scientist’s D-index using information gathered from OpenAlex and CrossRef, which are the most trustworthy and well-known bibliometric databases of this type open to the scientific community. A comprehensive overview of our research process can be found on our methodology page.

Our goal
Our aim is to inspire researchers, businessmen and decision-makers around the world to explore where leading experts are heading and to give an opportunity for the entire scientific community to discover who the leading experts in specific fields of research, in different countries, or even within research institutions are.
