It reminds me a lot of <a href="http://en.wikipedia.org/wiki/Latent_semantic_indexing" rel="nofollow">Latent Semantic Analysis</a>, which similarly calculates similarity between terms by how often they co-occur in documents. The algorithm that LSA uses is a little more complicated, and, I think, might address some of the weaknesses pointed out in the paper. I think it might be neat to try to combine the two approaches, maybe by using google to find a more "interesting" document set to feed to LSA. Interesting work!
