lsa on term document vector matrix

hi all, Can somebody help me to figure out how can I use "jama svd package" to apply LSA to the "term document vector" produced by lucene? Yours Sincerely, Nitin

semantic vectors

hi all, I want to know everything about semantic vectors. I want to know how does it indexes the documents such that the results produced are semantically better than normal search. I also want to know how it is different from semantic web, which uses the concept of ontologies and metadata.
