Performance Ranking of Scientific Papers for World Universities

The Performance Ranking of Scientific Papers for World Universities (NTU Rankings)^[1] is a ranking of world universities compiled by National Taiwan University annually since 2012.^[2]

This publication ranks world universities by a certain criteria of scientific paper volume, impact, and performance output. The ranking was originally published from 2007 to 2011 by the Higher Education Evaluation and Accreditation Council of Taiwan^[3] and has been published since 2012 by the National Taiwan University. It uses bibliometric methods to analyze and rank the scientific paper performance. In addition to the overall ranking, it includes a list of the top universities in six fields and fourteen subjects.^[4][5]

The rankings were introduced in 2007. The original ranking methodology favored toward universities with medical schools. In 2008, HEEACT began publishing a "Field Based Ranking" including six fields: agriculture and environmental sciences (AGE), clinical medicine (MED), engineering, computing, and technology (ENG), life sciences (LIFE), natural sciences (SCI), and social sciences (SOC).^[6]

In 2010, HEEACT began publishing subject rankings in fields of various field of science and technology. Science fields are divided into physics, chemistry, mathematics, and geosciences. Technology fields are split up into electrical engineering, computer science, mechanical engineering, chemical engineering (including energy and fuels), materials science, and civil engineering (including environmental engineering).

HEEACT ended the Performance Ranking of Scientific Papers for World Universities Project in 2012. Due to disagreement about ranking results, the Taiwanese education authorities announced that the government would no longer support the Higher Education Evaluation and Accreditation Council of Taiwan to do this ranking.^[7]

The HEEACT rankings used the following criteria:

• Research productivity (weighed 20%)—The number of published articles of the last 11 years (10%) and the number of articles of the current year (10%).
• Research impact (weighed 30%)—Number of citations of the last 11 years (10%), the number of citations of the last two years (10%), and the average number of citations of the last 11 years (10%).
• Research excellence (weighed 40%)—The h-index of the last two years (20%), the number of highly cited papers (15%), and the number of articles of the current year in high-impact journals (15%).

Quantitative data were drawn from Science Citation Index (SCI) and Social Sciences Citation Index (SSCI). The data were normalized by faculty number to account for different institution sizes. The indicators used in this methodology highly emphasized research quality (80% of the performance score) and short-term research performance (55% of the score).

The current NTU rankings use the following criteria:^[8]

• Research productivity (weighed 25%)—The number of published articles of the last 11 years (10%) and the number of articles of the current year (15%).
• Research impact (weighed 35%)—Number of citations of the last 11 years (15%), the number of citations of the last two years (10%), and the average number of citations of the last 11 years (10%).
• Research excellence (weighed 40%)—The h-index of the last two years (10%), the number of highly cited papers (15%), and the number of articles of the current year in high-impact journals (15%).

オーストラリアの高等教育機関は、HEEACTが作成した2007年の世界大学科学論文ランキングは、その厳密な方法と、より控えめな範囲によって可能になった確固たる結果から、現在の世界大学ランキングに有用な追加であると指摘した。^{[ 9 ]} HEEACTランキングについては他にもコメントがある。中国科学技術情報研究所の上級研究員である呉一山氏は、HEEACTランキングはこれまで見た中で最高のランキングシステムだと主張した。呉氏は、HEEACTランキングは大学の長期的および短期的パフォーマンスの両方を考慮していると指摘した。長期的および短期的ランキング指標を組み合わせるという考え方は先駆的な考えである。^{[ 10 ]} リチャード・ホームズ氏はUniversity Ranking Watchに投稿し、「上海ランキングは他のランキング（米国の大学のごく少数のサンプルに基づく）と高い相関関係を示しているが、台湾のHEEACTランキングはやや優れている」と指摘した。^{[ 11 ]}トロント大学の研究担当副学長であるポール・ヤング教授は、「HEEACTランキングは比較的新しいものですが、世界中の大学が行っている研究の量と質を測る上で重要かつ方法論的に堅牢な指標です」と述べています。^{[ 12 ]}国立台湾大学の学務部長である蒋文黄氏は、「HEEACTによる2009年世界大学科学論文パフォーマンスランキングは客観的な数値に基づいて実施されています」と述べています。^{[ 13 ]}
