Hello,
I have a project which indexes and scores documents using Lucene. However,
I'd like to do that using semantic indexing (LSI, LSA, LDA or Semantic
Vectors).
I've read old posts and some people said that Semantic Vectors plays well
with Lucene. However, I noticed that its c
It doesn't look too active, but you might check out:

Otherwise, Mahout has some of the basis for it but you would have to do some
work.

Zarrinkalam,

Hasn't the original patent expired?

Nitin,
LSI is patented so it's not been a flurry of implementation attempts.
However, SemanticVectors is a library that does similar approaches to
LSA/LSI for indexing and is based on Lucene's term-vectors.

Hi,
perhaps I can say a few words about CNS.
I evaluated spreading activation search (which is what CNS is based
on) for my master's thesis. I must conclude that SA is a rather fickle
method -- if you read Preece's thesis, you will see that it can b

We're also thinking about implementing something similar to LSI within
ActiveMath which is lucene-powered where both formulae and text
searching would benefit of the latent-semantic-similarity. I've been
refrained of doing "exactly this" at least since LSI is patented. T
Yeah, its Latent Semantic Indexing

It depends on the kind of implementation you are thinking of.
You can use Lucene to create the inputs to the LSI, and then use them in
your own system. I've written that code and it works, for searches and

I use my own LSI implementation based on Lucene for text clustering.
I've done some tests, but I do believe that integrating LSI onto the lucene
search subsystem (i.e. creating something like LSISimilarity) is not an easy
task

I've met other persons with such needs and we would also be interested.
Unfortunately, this seems not to be available.
A clear issue might be that LSI, in its original form at least, is
covered by an US patent. But maybe someone finds another form which is
not.
