I need to evaluate my implementations of Turney's web PMI algorithm, and Hu & Liu's wordnet alorithm for sentiment orienation analysis. I was wondering, is there a test data set out there I can use, or some other way I can get a good handle on how well they're working? (I'm looking at them in the context of customer reviews of cameras.)
