Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: I heard Steven Selengut on a talk-radio program and was intrigued by the premise of the book. My intrigue led me to purchase the book, which was an eye-opening experience. After reading it, I'm convinced I had been sucked in by my former financial advisors to purchase products which I didn't need and cost too much. Instead of jumping in with both feet and totally revamping my investment habits, I've followed Steve's advice and gone into it slowly. I'm migrating from mutual funds (and annuities) to individual, high quality equities. My next step is to start purchasing bonds, as soon as the rates recover. Although the information provided isn't anything new, it was a slap in the face to make me stop my destructive investing habits.
Solution:
Positive
