Hi all, This might be a little off topic to lucene. But i guess it is still in the interest of IR. I wanted a rough idea on what applications/fields LDA has been used and observations. If any body did a simlar study (other than that given in the paper by Blei et al . ), that will be of great help

I'm sure your evaluation is correct from the inspection I have made of the NITLE effort, e.g. the need for tweaking. I will follow up your links when I have a chance, and thank you for them. I didn't know that about Maciej Ceglowski. People do move on. I wish him luck (in case he is reading this or

There seem to be quite a few alternatives around. I would be interested in comments on the following:- The work at NITLE using Contextual Network Search (CNS) a graph-based alternative to LSI. This work *[PDF]* An Introduction to *Random* Indexing

It depends on the kind of implementation you are thinking of. You can use Lucene to create the inputs to the LSI, and then use them in your own system. I've written that code and it works, for searches and clustering. But if you are figuring out an LSI enhanced Lucene search system (based on a spec
