István Bíró, Jácint Szabó
2010 arXiv   pre-print
In this paper we demonstrate the applicability of latent Dirichlet allocation (LDA) for classifying large Web document collections.  ...  The inferred LDA model can be applied for classification as dimensionality reduction similarly to latent semantic indexing.  ...  Acknowledgment To Zoltán Gyöngyi for fruitful discussions and for providing us with the DMOZ labels over the UK2007-WEBSPAM corpus, and to Ramesh Nallapati for providing us their link-PLSA-LDA and pairwise-link-LDA  ...
