Reliable Asian university rankings datasets suitable for evaluating applications to a graduate program Our (American) university has a lot of applications coming in from Asia- especially China, India, Japan and Korea. 

Each of these seems to follow a different grading scheme and it is hard to do  apples-to-apples comparisons of students scores across universities. We don't request WES transcripts. 

What is a good way to normalize students across Asian universities? Which ranking schemes (global and local) are reliable? Do these ranking schemes provide fine-grained, easy-to-parse data that we can use for CS and ECE admissions (not just relative ranking)?

ADDENDUM: There seems to be an XY problem with the original question, as @FedericoPoloni points out. What we're interested in is indeed-- "What is a good way to compare transcripts for graduate admission, especially from Asian universities? Admittedly, this is a broad problem and solutions may be reductive or simplistic, but it seems unfair to not consider the quality of teaching, research and the cohorts worked with, when evaluating student transcripts.

The current answer and comments, while helpful, will leave admissions restricted to IIT, Tshingua, KAIST-- since we do not trust transcripts from other universities, and though exceptions can be one-off, this approach does not scale. I'd be grateful if you could share references to meaningful datasets and ideas to use the data without unfair bias.
I believe that using university ranking as a criteria for admission is fundamentally unethical. 

Extremely good students end up going to middling or poor undergraduate institutions for any number of reasons. To downgrade somebody's application just because they went to a mediocre institution is actively going against the academic ideal that merit should be able to rise, and even poor institutions generally have at least a few students of excellent potential.  Complementarily, pedigree is no guarantee of quality: rubbish students graduate from elite institutions all the time.

Now, there is, of course, a strong correlation between the quality of an institution and the quality of the students that it produces, and there are, of course, basic matters of accreditation: nobody should respect a degree from Trinity Southern University.  In general, however, you should judge the students and not the institutions.

So, how do you judge a student from Asia? The same way that you judge a student from an unfamiliar university in Europe or North America, by the accomplishments for which they can give evidence.  To judge classwork, one of the methods is to ask which textbooks were used (this is what some MIT departments do).  To judge other work, look for the concrete products, such as research papers, code or web pages online, etc.

Students from universities you do not know will still be at a disadvantage, and doubly so for students from a very different environment and who may lack English communication skills, such as will often be the case for many Asian universities.  But you can at least take steps to not prejudice yourself unduly by sorting their universities by their ability to game semi-arbitrary ranking systems.
