Sounds like interesting stuff.
Jon Kleinberg at Cornell is doing some research into topic "burst" identification in real-time text data streams. You can have a look at some of his preliminary results here. It might be interesting to compare whether your results match his. His stuff is all for English (of course).
I'd be curious to hear about how your doing your identification---I'm assuming a kind of basic separation of lexemes into categories (positive, negative, neutral), or do you have a level of abtraction there. If you'd like to share, you can reach me via e-mail from my homepage or /msg me.
Where the language modules are concerned, I really feel for you. Due to time constraints, we have kludged together a sentencizer for French because there was not one readily available to suit our needs, but due to everything else being prioritized above it, it is utter crap (does the job mostly right, but with unpredictable results).
