Our ranking of top scientists in Japan includes leading scientists from all major areas of science. It was based on a meticulous examination of 166,880 scientists on Google Scholar and Microsoft Academic Graph.
The H-index threshold for approving a scholar to be considered for the ranking was set differently for each scientific discipline, but was in most cases equal to 30 or 40. The inclusion criteria for scholars to be considered into the ranking of top scientists in Japan are based on the H-index, proportion of the contributions made within the given discipline in addition to the awards and achievements of the scientists. Only top 1000 scientists with the highest H-index are featured in the ranking.
Because the main goal is to ensure that only genuine researchers are included in the ranking, we believe that numbers are never meant to be an absolute measure to quantify the contributions of scientists. This is why we manually verify each profile and cross-correlate it against publications in a wide range of credible sources. Even though it’s not a metric defining a scientist’s position in the ranking, the amount of documents published in major journals and conference proceedings should constitute a reliable secondary indication of their contribution to research in a given discipline. Position in the ranking is based on each scientist’s H-index using data compiled from Microsoft Graph, which is one the most prominent and well-established bibliometric database of this type available to the scientific community. A detailed definition of our research process can be found on our methodology page.
Our aim is to inspire scholars, entrepreneurs, and decision-makers worldwide to explore where leading experts are heading and to provide 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.
