The 2007 ranking methodology was alleged to have favored universities with medical schools, and in response, HEEACT added assessment criteria. 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). The ranking was renamed as National Taiwan University Ranking in 2012.
