Press release from Springer Nature
NTU at 32 in global index of universities with NUS at 40
Singapore is 17th globally for its contribution to high-quality scientific research papers, according to the 2016 Nature Index Tables released together today. That puts it behind Australia (in 12th place) but in front of Taiwan (18) and Russia (19).
Nanyang Technological University (NTU) appears as Singapore’s leading research university in the index, placed 32 in the world among universities ahead of National University of Singapore (NUS) at 40. Both are well in front of Seoul National University and of Australia’s top universities.
Globally Harvard University is the leading university followed by Stanford University, The University of Tokyo and Massachusetts Institute of Technology.
In a separate table looking at all types of institutions worldwide involved in research including private companies, the Agency for Science, Technology and Research (A*Star) is placed at 162 while NTU is at 37 and NUS at 46.
The Nature Index is built on an institution’s contributions to about 60,000 high-quality papers each year and considers both the number of papers and the relative contribution of the authors.
The Nature Index Tables show the Nature Index calendar year outputs for the last four years. Between 2012 and 2015, Singapore’s contribution to the index across all types of institutions grew by a compound annual average of 1.5 per cent. Over the same period, China’s contribution grew by an annual average of 12.8 per cent and Australia grew by an average 3.3 per cent per annum.
The NUS researchers were listed as authors on 465 papers, 42 more than their NTU rivals. However, papers with NTU authors had fewer authors from other institutions, bringing NTU to the top of the Nature Index for Singapore in terms of contribution of their authors. The good news for NUS is that the index shows it is slightly more collaborative than NTU.
“Singapore’s output is remarkable considering its size and it is only matched by other research intensive small countries like Switzerland, which also punches well above its weight,” says David Swinbanks, the founder of the Nature Index.
The index shows the rapid growth in high quality science at NTU, which has averaged 5.4% growth in contribution to the index over the past four years. “NTU has come out of nowhere. Ten years ago NTU was not a major contributor to the sort of high quality basic research tracked by Nature Index. But under the leadership of President Bertil Andersson, it has leapt not just to number one in Singapore but into the top ranks of universities worldwide in the Nature Index,” says David Swinbanks.

About the Nature Index
The Nature Index database tracks the author affiliations of 60,000 high-quality scientific articles each year. The Nature Index Tables, which show the Nature Index calendar year outputs for the last four years, are released today for the first time. The tables reveal absolute publication productivity in broad subject areas for countries, universities, companies and hospitals. Variance in article output compared with prior year is included. Measures include article count (AC), the total number of affiliated articles; fractional count (FC), which accounts for the relative contribution of each affiliation to an article; and weighted fractional count (WFC), which applies a weighting to FC to adjust for imbalances in the index’s subject coverage. (See notes for editors for full definitions of measures.)
The Nature Index website — www.natureindex.com — provides free, quick and simple access to the recent research profiles of over 8,000 global institutions and 150 countries. The data behind the 2016 tables remains freely accessible, enabling users to examine patterns of publication and collaboration down to the article level where measures of their media impact are tracked in real time.
To accompany the release of the Nature Index Tables, a News section has been added to the Nature Index website. Here, the Nature Index editors will provide ongoing editorial analysis and commentary around the most recent data, including organisational and country-level profiles and infographics. The analysis will include additional information from other data sources, such as demographics, national spend on research and development, and changes to science policy and funding, that will help to put the Nature Index data into context.
David Swinbanks, Founder of the Nature Index, commented: “The Nature Index delivers a freely accessible and straightforward way to analyse high quality scientific research output that complements the other metrics and evaluation tools currently available to the research community. By focusing on a relatively small number of articles that have been identified as high quality by an independent group of practising scientists from relevant disciplines, we aim to provide a targeted view of high quality output for institutions, policy makers, research analysts, commercial organizations and the wider scientific community. Now with over four years of data, the Nature Index is becoming an increasingly powerful tool that provides more than just a snapshot as the addition of each year’s data helps to elucidate trends in high quality research output and changing patterns of collaboration over time.”

Notes for editors
About the Nature Index metrics
First launched in November 2014, research articles included in the Nature Index are collated from a group of 68 high-quality natural science journals, which were selected by two independent panels of active scientists, chaired by Professor John Morton (University College London) and Dr Yin-Biao Sun (Kings College, London).
Responses from over 2,800 individuals to a large scale survey were used to validate the selections. Springer Nature estimates that these 68 journals account for nearly 30% of total citations to natural science journals.
A rolling 12 month snapshot of data from the Nature Index is openly available under a Creative Commons license at natureindex.com, so that users can analyse scientific research outputs themselves. On the index website, an institution’s output of articles can be viewed across the 12 month period and broken down by broad subject area. International and domestic collaborations are also shown for each institution.
The Nature Index uses three measures to track affiliation data for individuals:
- Article count (AC) – A country or institution is given an AC of 1 for each article that has at least one author from that country or institution. This is the case whether an article has one or a hundred authors, and it means that the same article can contribute to the AC of multiple countries or institutions.
- Fractional Count (FC) – FC takes into account the relative contribution of each author to an article. The total FC available per paper is 1, and this is shared between all authors under the assumption that each contributed equally. For instance, a paper with 10 authors means that each author receives an FC of 0.1. For authors who have worked with joint affiliations, the individual FC is then split equally between each affiliation.
- Weighted Fractional Count (WFC) – applies a weighting to the FC in order to adjust for the overrepresentation of papers from astronomy and astrophysics. The four journals in these disciplines publish about 50% of all papers in international journals in this field — approximately five times the equivalent figures for other fields. Therefore, although the data for astronomy and astrophysics are compiled in exactly the same way as for all other disciplines, articles from these journals are assigned one-fifth the weight of other articles.
