Hi,
I am currently implementing some sort of semantic indexing with Lucene. I'm
using lucene index to generate TFIDF matrix and then apply singular value
decomposition on it. So I get some kind 2D vector representation for each
document. The distance between two vectors is their relevance.

stion?

Is it possible to combine Lucene and multi-dimensional scaling in some way?
I don't know. Is there a good SVD package for Java?
I think about implementation with Jama, there is a SVD class, but I don't
know yet if it's good or not

Hi
I need some kind of implementation of SVD (singular value decomposition) or
LSI with Lucene engine. Have anyone any ideas how to create a query table
for decomposition? The table must have documents as rows and terms as
columns, if a term is presented in the docuement, the corresponding field
