Is there any open source implementation of LSI in Java? I want to use that library for my project. I have seen jLSI but it implements some other model of LSI. I want a standard model.

Have you considered LDA (Latent Dirichlet allocation)? I haven't really either, but I encountered the same problem with LSI recently (patents). From what I understand LDA is a related/more powerful technique. http://en.wikipedia.org/wiki/Latent_Dirichlet_allocation apparently has some links to open-source implementations.
