So my problem is as follows: I get responses (such as "yeah whatever", "yes do it", "no don't do it", "nah", "yeah do it" etc.) and I need to classify them into either "yes" or "no" i.e. a binary classification. What algorithm and features should I use for this?
My thoughts yet: Use an averaged perceptron or logistic regression or boosted trees. As for features, I was considering using the tf-idf score and sentiment analysis but I can't think of much else.
