Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Input: Consider Input: The best thing I found in this book is the picture on the cover. Well, actually the uncropped version in chapter 5. Beyond that, I found everything else to be non-practical from a design perspective. A photo of a filthy dust collector area when discussing the advantages of central collection or electrical wiring that would never pass inspection is typical. I'd rather see plan views of real shops that work with reasons for the decisions made.

Output: Negative

Input: Consider Input: Great book for people that need to write email. It would be nice to review the grammar rule's from time to time.

Output: Positive

Input: Consider Input: I rarely write reviews, but after I received this Halloween book, if you would even like to put it in that catagory, I felt I needed to save anyone from buying it!An avid celebrater of Halloween, I thought that I had to have this boook for my collection--the title itself was SO catchy. After looking at it, the book was returned.Words cannot even describe the dissappointment I felt after glancing through it. Boring, old, uninviting, crafty suggestions. If you are looking for a good Halloween book for the not too crafty or the not too gory, games, treats, decorations, try 101 Halloween Ideas.
Output: Negative
