Blei and Lafferty clustering
The April 30 economist has a layperson's description of what looks
like an interesting topic clustering system by Blei of Princeton and
Lafferty of CMU. Anyone know anything about it?

that is called topic model.

Likely hierarchical LDA. Blei refers to this class of latent factor models
as topic models.

I found the paper subsequently, and it's all LDA!

Given that it is David Blei, it is almost certainly a variant of topic
