The reason may be that there are some patents that cover LSI (I think owned by telcordia).

Subject: Latent Semantic Analysis?


I tried googling "latent semantic lucene". Got nowhere. Just a curiosity,
is there a project 'out there' that is looking at adding clustering,
perhaps using LSA to Lucene?

Hello Lucene Developers:

I have been lurking on this list for a while, and this question is good
excuse to introduce myself. I have an implementation of LSA that I have been
planning to modify to fit into the Lucene framework Real Soon Now. I would
be interested in collaborating with others, or just hearing how it should
work and/or design thoughts.

Ive been thinking about LSA as a search algorithm; i have some other ideas
about clustering, but havent had time to test any of them.

Some details of previous LSA work are available at:

http://www.unidata.ucar.edu/staff/caron/faqo/index.html

(in fact, if you look at the FAQO demo, you will notice that I've been
archiving this maillist since Oct, so you can try LSA out on it. PS: sorry i
dont have any real docs yet, but have a look at the online help).

Dmitry Serebrennikov has written code that makes it substantially easier to
do clustering and LSA on Lucene indexes. He has not yet had the chance to
integrate this into the current version of Lucene, but you can use it with
1.2 RC1. See the following for details:
