I don't think it works correctly though... it uses "Author" as the first link whereas the first link in the text of the article is "webcomic" ("Author" is in the summary pannel on the side)
The same happens for cities or locations, where there is usually a "Coordinates" in the upper right corner. Still, I did it manually in text bodies, and you eventually end up to Science or Mathematics, which leads to Philosophy.
