The Nature Index is a guide
The Nature Index: Online access to high-quality scientific research output and collaborations in South Korea, Japan, and other natural-science institutions in 2019-2023
A description of the terminology and methodology used in this supplement, and a guide to the functionality that is available free online at natureindex.com.
The Nature Index shows absolute and fractional counts of article publication at the institutional and national level and shows an indicator of global high-quality research output and collaboration. Data in the Nature Index are updated regularly, with the most recent 12 months made available under a Creative Commons licence at natureindex.com. The database is created by Nature Portfolio.
The total number of articles in Nature Index journals has a small variation thanks to the adjusted share. To arrive at it you have to calculate the percentage difference between the number of articles in a given year and the number of articles in a base year.
The sum of the shares of both institutions on the papers to which both have contributed is called the bilateral collaboration score. A bilateral collaboration can be between any two institutions or countries/territories co-authoring at least one article in the journals tracked by the Nature Index.
You can find the list of recent outputs from a profile page after each query, and it is possible to drill down for more information. The journal can be used to display the articles. Research outputs are categorized according to subject area. The pages list the institution or country’s top collaborators and its relationship with other organizations. Users can track an institution’s performance over time, create their own indexes and export table data.
The natural-science output of the fastest rising institutions in the country has shown modest gains in recent years, which could indicate a stable performance in recent years. Over the period, the largest percentage increase came from the only corporate institution in this list, the Samsung Group. This was from a much smaller adjusted Share of 10.77 in 2019, however, compared with Seoul National University at 174.97.
South Korea has the most researchers in science, technology and innovation roles (full-time equivalent) per million inhabitants — and by a large margin. It is notably the only non-European country in the top 10 by this measure in 2021. Japan is ranked 11th.
The fastest-rising institutions in four natural-science subjects, and in the natural sciences overall, are shown for the period 2019 to 2023. Institutions are ranked according to change in adjusted Share, which for the Pohang University of Science and Technology was larger in the physical sciences than it was in the natural sciences overall.
