Are there any good sentiment analysis gems that use actual machine learning? Looked into the sentimentalizer gem(the code on github seems a bit simplistic), but not sure how good it is compared to, say, Google's Cloud Prediction API.
I would imagine feeding things into Google's Prediction API would be pretty great. It might be a bit more involved for than these gems, but is probably worth it if the machine learning aspects are important to your product. Hopefully get dive into that soon.
Whenever i try to call Tweet.sync("something") it says undefined method search for Twitter::Streaming:: like that. I am doing exactly as you told in the tutorial.
