I did some work about 5 years ago, where we took a dump of Wikipedia,
and computed the Jensen-Shannon divergence between the documents. The
idea was that two documents with small JS are closely related in
meaning. We were trying to see if the induced network from
JS-divergence had similar network properties to network of networks
between words in the online dictionary WordNet.
The short answer was - they don't. Then funding ran out, and I moved
onto other things :).
Cheers
