Telcordia (formerly Bellcore) offers LSA/LSI software for academic use.
To request a copy, go to:
http://lsi.research.telcordia.com/
This package handles all the steps in applying LSI to a corpus. However,
it is only available as precompiled binaries for Solaris, I think.
You might also try Michael Berry's SVDPACK (Fortran) or SVDPACKC (C port),
available from netlib.org. This won't handle the creation of
term-document matrices, but provides open source SVD software for large,
sparse matrices. It will compile under a variety of Unix-type operating
systems.
Best.
