Task: Sentiment Analysis
Input (English): I purchased this book to help me get back into reading for a while. I'm glad others had different experiences than me, but from what I've read on Amazon, there are just too many mistakes in the text. You have to believe that they spell all of their words correctly, sometimes it's hard to tell. In addition, at times when I see errors, I wish he clarified whether or not you can make them yourself if you're unable to find another speller. He doesn't even list it anywhere. My advice, don't buy it.
Output (English): Bad review
