HEEACT further provides subject rankings in science and technology fields.
It also ranked the top 300 universities across ten science and technology fields. They were: articles published over prior 11 years; citations of those articles, "current" articles, current citations, average citations, "H-index", number of "highly cited papers" and high impact journal articles.
Some rankings evaluate institutions within a single country, while others assess institutions worldwide.
The subject has produced much debate about rankings' usefulness and accuracy.
This project employed bibliometrics to analyze and rank the performance of the 500 top universities and the top 300 universities in six fields.The methodology pools universities from ARWU, HEEACT, Times-QS and Webometrics and a pool of experts formed by project officials and managers to determine the rating scales for indicators in seven areas.It considers academic performance, research performance, faculty expertise, resource availability, socially significant activities of graduates, international activities, and international opinion.The six field-based rankings are based on the subject categorization of WOS, including Agriculture & Environment Sciences (AGE), Clinical Medicine (MED), Engineering, Computing & Technology (ENG), Life Sciences (LIFE), Natural Sciences (SCI) and Social Sciences (SOC).
The ten subjects include Physics, Chemistry, Mathematics, Geosciences, Electrical Engineering, Computer Science, Mechanical Engineering, Chemical Engineering (including Energy & Fuels), Materials Sciences, and Civil Engineering (including Environmental Engineering).Rankings are based on quality of education, alumni employment, quality of faculty, number of publications, number of publications in high-quality journals, citations, scientific impact and number of patents.
