Top Computer Science Scientists in Japan

This 2021 7th edition of top scientists ranking for computer science was published by Research.com, one of the major websites for computer science research offering credible data on scientific contributions since 2014.

The ranking contains h-index, publications and citations values collected on June 25th 2021 Show more

Our top scientists ranking is a reliable list of leading scientists from the area of computer science, based on a meticulous examination of more than 6300 profiles on Google Scholar and Microsoft Academic Graph.

The h-index threshold for approving a scholar to be considered is set to 40 if most of their publications are in the field of computer science. The threshold was determined based on the recommendation by J. E. Hirsch, PhD in his “An index to quantify an individual's scientific research output” paper where he pointed out that an h-index of 40 characterizes outstanding researchers.

Our goal is to ensure that only genuine researchers are included in the ranking. That is why we also 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 area.

Position in the ranking is based on each scientist’s h-index from Google Scholar, which is 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.
