Any help would be very appreciated!

Re: Source code implementing Latent Semantic Indexing

Google suggests these sites:

http://www.cs.utk.edu/~lsi/
http://javelina.cet.middlebury.edu/l...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...._matrices.html
