Hey wfunction

I believe we know exactly what the matrix is, based on the hyperlink structure itself. It's updated and displayed on the vis here based on that, too.

btw, David Austin's article on PageRank is highly recommended : http://www.ams.org/samplings/feature-column/fcarc-pagerank

Fair enough. I'm thinking in particular of a paper I read that used pagerank for word sense disambiguation [1]. It's actually variant of pagerank, so the high level description in terms of probabilities (which I read several of) didn't take me very far. In order to come to grips with the technique I ended up actually implementing it and trying it on some toy datasets. This definitely would have helped me in that case.

[1] http://www.aclweb.org/anthology/E/E09/E09-1005.pdf It's interesting research, but it unfortunately turns out that even the best results in word sense disambiguation aren't good enough for a lot of applications. I wish I had 2 years to do nothing but play around in this field.
