I have a document-term matrix and I performed SVD on it. How can I cluster terms based on the singular values?

Is there any relationship between SVD and factor analysis?

    $\begingroup$ latent semantic analysis (LSA) seems related en.wikipedia.org/wiki/Latent_semantic_analysis $\endgroup$ – dontloo Mar 5 '16 at 2:06
  • $\begingroup$ You could just take the eigenvector matrix that corresponds to your terms (i.e., A^TA or AA^T), turn it into a distance matrix of some kind, and then use your choice of clustering criterion. $\endgroup$ – Marshall_soc Mar 5 '16 at 3:32
