US news national university ranking has an aura of authority in USA. Everyone consider that ranking pretty accurate.
HOWEVER, this international ranking is a joke. No sane one in USA takes this international ranking seriously. Because it puts too much weight on things like total citation/ Ph.D gradautes number and etc which essentially favor bigger institutions. The bigger the university is, the better position it is likely to get. That's why smaller ones get a lower ranking and Chinese universities have better rankings. For example, Princton is Number 1 in the national ranking but only No. 12 in this internationl ranking.
USNews 国家大学排名是权威, 但是这个国际排名就是个玩笑。 他所采用的排名方法不利于规模小的学校(例如普林斯顿)和文科比理科强的学校(例如耶鲁)。相反的,规模大理科强的学校就很占优势。
从这些例子就能看出这个排名的不科学性:
Computer Science:
#7 Tsinghua University
#8 Nanyang Technological University
#15 National University of Singapore
#17 Carnegie Mellon University
Are they ranking them in REVERSE order????
