Hello Marcelo, Semiocast had released some time ago an API that could be used for what you are trying to do. You can look it up here: http://developer.semiocast.com/ More specifically, for a tutorial on using the API on tweets: http://developer.semiocast.com/tutorial/twitter
Hope you'll find this interesting. Bear in mind that, as you say, interpreting what the user wrote can sometime be really difficult (even for a human), but statistically we have some decent results. Cheers, Jean-Charles PS: I'm resending this email as the first one did not went through...
