Correct me if I am wrong, but even from the summary I get a strong suspicion this "research" is heavily flawed. I mean, the only way for "Carl Linnaeus" would be on the top spot would be if you blindly applied a sort of page-rank algorithm forgetting to only include non-standardized parts of pages. A significant percentage of Wikipedia pages on all languages are about the various species of plant or animal life, all of which have a stub which contains the link to "Scientific classification" perhaps also to "Binomial name", both of which feature Linnaeus prominently.
It reminds me a spider my boss had built to get a few thousands of pages to construct a word frequency list, and I had to point out that it needed some work, since words like "print", "home" etc were not in the top-5 most common words of the English language.
