TASK DEFINITION: Given an English language product review, determine if it is a Good Review or a Bad Review. A good review is one where the product's review has positive tone and Bad review is one where the tone of product's review is negative.
PROBLEM: My son was very upset when the book didn't have pages. I called and received a new book, which also wasn't the correct book. Needless to say it will go in the garbage. What a rip off! They should take out all reviews that are not written by "Amazon Verified Purchase". This has never happened before.

SOLUTION: Bad review

PROBLEM: The book is very short with just enough information,I wish there was more detail or maybe a study at the end of his book.

SOLUTION: Good Review

PROBLEM: The first month we tried to use, it looked promising with no problems. Last week, when I was in the process of using this vacuum for my hardwood floors, I smelled something burning and discovered that a piece had burst off one side and is protruding through my carpet. For me, that's hardly worth spending so much on an unused, non-working vacuum!! At least it's going back, thanks Amazon.com.

SOLUTION:
Bad review
