In their own words,

Here we demonstrate a method to build a semantic network from published scientific literature, which we call SemNet

where they use Wikipedia as a source of concepts forming nodes in the knowledge network, and the published literature as a source for edges linking those nodes together with the strength of those edges.

I don't know how useful this will end up being, but it's worth a look if you're interested in that genre.
