I'm trying to model twitter stream data with topic models. Gensim, being an easy to use solution, is impressive in it's simplicity. It has a truly online implementation for LSI, but not for LDA. For a changing content stream like twitter, Dynamic Topic Models are ideal. Is there any way, or even a hack - an implementation or even a strategy, using which I can utilize Gensim for this purpose?
Are there any other python implementations which derive (preferably) from Gensim or independent? I am preferring python, since I want to get started asap, but if there is an optimum solution with some work, please mention it.
