oh, my university is on there (90's range). Neat.
But I feel that citations, publications, and patents should definitely not be included as a measure of quality of the education, since those don't actually relate to each other. Most of the people you have read about in lectures and books tend to be people in academics or just outside of it with only a minor amount of publications compared to current expectations.
To put it bluntly: a citation machine-man tends to be intellectually arid and not a source for creative new theory (or data, to reframe existing ones) or pushing boundaries.
It's also way too easy to publish articles that are actually completely meaningless because they have no theory in them. Say, "the correlation between posting on neogaf and being a shitheel". You get an answer alright, but it's without a process of expected explanations / predictions / hypothesis (theory), which is therefore junk information. It tells you nothing. Yet these "bullshit publications" (my words, not someone else's) do count towards credibility.
This is particularly heavy towards US institutions, meaning that the over-representation of US universities in the top 20-30 is likely a result of a biased model, not a more realistic, human, measure of quality.
"Man is the measure of all things", not an algorithm. Ironically I have Colossus (1970) running in a different window while typing this. Feels meta.
