Source code implementing Latent Semantic Indexing

[yassine]

I'm looking for a source code using the LSI technique (Latent Semantic Indexing) for information retrieval.
Any help would be very appreciated!

Google suggests these sites:

http://www.cs.utk.edu/~lsi/
http://javelina.cet.middlebury.edu/lsa/out/lsa_definition.htm

Neither suggest that the source would be trivial. :-)

Depent of what language are you going to use: There are many exemples in R language for a complete LSA but also, there is some free code for SVD for .NET, JAVA and C++, and the olders FORTRAN and ANSI C. http://perso.wanadoo.fr/jean-pierre.moreau/c_matrices.html
