Project 1: Attack on State of Art lexical resource journey
Status: completed
This was the first project under the belt of sentiment analysis. It aimed validating the present lexical resource(you name it :D) for its correctness and definitions. And the result suggest that "ummm...ohhh....okkk" type. More coming on after the report gets validated. More on this after Jan 15,2010.
The verdict is out. The resource we did our experiment is SentiWordNet-> for more details chip in a mail, I would be happy to share my result.
Project 2: Boost up accuracy of a SA system

What are the good features for SA classification- or did we find them before, but just forgot them.

Project 4: Cross domain sentiment analysis
Status: Completed
