Don't LSA techniques usually involve finding the SVD or eigenvectors of a large matrix? In this case I would strongly doubt that something like this exists in Java, although I've been wrong before...
i am desperately in need of algorithm or implementation of latent semantic analysis . so please help me with the code if you have one.

Don't you generally do LSA with sparse matrices? Otherwise they're gigantic because you can have thousands of words. I'm not sure, though. But if so, NiST doesn't seem useful.
Don't you generally do LSA with sparse matrices?I think you use singular value decomposition to make the matrix more sparse. I haven't used the NIST package, but it does supply an SVD class.

I am planning to develop Automatic Essay Evaluation system for Amharic language (Ethiopian working language) among the state of the art methodology i have chosen LSA and java as development tools, but i don't want to hide you that i have gone through a lot of challenge coz lot matimatical and statistical concept are there so would you please help me in providing any information,tools, codes which you you think that is important i am so grateful for that
thanks in advance

How To Ask Questions The Smart Way
Eric Steven Raymond
Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal - in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.
