NTU Ranking - National Taiwan University Performance Ranking of Scientific Papers for World Universities  is designed for research universities and is based on eight indicators representing three different criteria of scientific paper performance: research productivity, research impact and research excellence. The indicators are designed to compare both the quality and the quantity of scientific papers in each university from both the long-term and short-term perspectives. Although the incorporation of short-term indicators increases the complexity of the ranking, it also enhances the sensitivity of the ranking methodology and is able to prioritize universities with recent progress in research. 

This ranking system is based exclusively on the qualitative and quantitative performance of scientific papers. It does not assess the overall university performance in teaching, research, and administrative activities.

RESEARCH PRODUCTIVITY (25%)

Number of articles in the last 11 years (10%)  -  data drawn from ESI, which includes 2009-2019  statistics articles published in journals indexed by SCIE and SSCI.

Number of articles in the current year (15%) - relies on the 2019 data obtained from SCIE and SSCI.

RESEARCH IMPACT (35%)

NTU Ranking considers both the long-term and short-term impact of a particular research and seeks to provide a fairer representation of a university’s research impact regardless of its size or faculty number. Thus, this ranking system measures research impact by the number of citations in the last 11 years, the number of citations in the last 2 years, and the average number of citations in the last 11 years.

Number of citations in the last 11 years (15%) - 2009-2019 citation statistics from ESI.

Number of citations in the last 2 years (10%) - 2018-2019 citation statistics from SCIE and SSCI in WOS, which include citation statistics updated to the dates of retrieval.

Average number of citations in the last 11 years (10%) - the number of citations in the last 11 years (2009-2019) divided by the number of articles in the last 11 years.

RESEARCH EXCELLENCE (40%)

H-index of the last 2 years (10%)  - the quantity and quality of a university’s research via the use of the 2018-2019 SCIE and SSCI data.

Number of Highly Cited Papers (15%) - Highly Cited Papers as SCIE/SSCI-indexed papers that are cited most (in the top 1% of the total papers indexed in the same year) within the last 11 years (2009-2019).

Number of articles in the current year in high-impact journals (15%)  - the number of citations of the papers published in a particular journal within the previous two years divided by the number of that journal’s papers within the previous two years ( high-impact journals are defined as those whose impact factors are ranked in the top 5% of the total journals within a specific subject category).
