Regarding "research.com", which is linked from the article: this is weird - some random observations...:

• Donald E. Knuth, the most eminent computer scientist alive, ranked 92nd (!) in computer science - seems off by about two orders of magnitde.

• Noam A. Chomsky, of whom some say he is the most-cited scholar alive (on the level of Aristotle), ranked seventh in the US. He gave theoretical computer science the Chomsky hierarchy and the Chomsky Normal Form, he has been called the "father of modern linguistics" (Hewbrew morphology, generative grammars, competence-performance distinction, Universal grammar, government & binding theory, the review of Skinner's book that single-handedly destroyed behaviorism, the 'minimalist' program, ...), in politology he is a long-standing and perhaps the most ardent and vocal critic of US foreign policy, supporter of Palestine (being a Jew himself), and in communications and media studies his book (with Herman) "manufactoring Consent" is a field-defining classic. - https://research.com/u/noam-chomsky

• regarding school rankings, in Germany, KIT (Karlsruhe Inst. of Technology) seems missing entirely, a top place in CS research.
