Sorry, I don't have any help, I'm just a regular joe looking at this stuff and taking particularly hacky ways to get the job done on the side (when I don't have other things going on. :-) ). The approach I've been taking initially is the bag-of-words approach. Looking forward I anticipate using some sort of ngram-based approach which clusters sentiment around phrases. These are stupid approaches, but I want to see how far I can push simple and stupid. ;)
