Latent Topic Models for Hypertexthttp://mloss.orgUpdates and additions to Latent Topic Models for HypertextenWed, 02 Sep 2009 15:40:42 -0000Latent Topic Models for Hypertext 1.0<html><p>A probabilistic generative model for hypertext document collections that explicitly models the generation of links. Specifically, links from a word w to a document d depend directly on how frequent the topic of w is in d, in addition to the in-degree of d. We show how to perform </p> <p>EM learning on this model efficiently. By not modeling links as analogous to words, we end up using far less free parameters, and obtain better link prediction results. </p></html>amit gruberWed, 02 Sep 2009 15:40:42 -0000 semantic analysistopic modelinggraphical modelsem
