Classifying survey response text SVM
Can you clarify what you're trying to predict with these responses?

My initial reaction is that with open-ended surveys you'll have a tough time implementing classification algorithms. Open-ended-ness means you don't have a finite feature space and thus you can't do the usual transformation of responses into a feature matrix.

However, there may be other ways to make this work. If you have 5 questions, for instance, you may be able to use sentiment analysis or other methods to come up with metadata about the open ended response that can help you design a classification scheme.
