ShanghaiRanking began to publish world university ranking by academic subjects in 2009. By introducing improved methodology, the Global Ranking of Academic Subjects (GRAS) was first published in 2017. The 2022 GRAS contains rankings of universities in 54 subjects across Natural Sciences, Engineering, Life Sciences, Medical Sciences, and Social Sciences. More than 1,800 out of 5,000 universities across 96 countries and regions are finally listed in the rankings. The GRAS rankings use a range of objective academic indicators and third-party data to measure the performance of world universities in respective subjects, including research output (Q1), research influence (CNCI), international collaboration (IC), research quality (Top), and international academic awards (Award). The index of international academic awards is based on Academic Excellence Survey (AES) conducted by ShanghaiRanking since 2017. Until March 2022, more than 1000 professors from top world universities have participated in the survey. Their responses have revealed 180 top journals in 52 subjects, 36 top awards in 29 subjects, and 31 top conferences for Computer Science & Engineering.
