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

Input: Consider Input: All of the good things said about "Helter Skelter" is true of the Kindle edition. What's more the Kindle edition has hyperlinked footnotes that actually work and take you instantly to Bugliosi's notes. But the trade-off is that with the Kindle edition THERE ARE NO PICTURES because of licensing issues. The print edition has lots of pictures, but many of the crime-scene photo's are censored.

Output: Positive


Input: Consider Input: I just returned from a month-long trip to Vietnam and Cambodia, and I found this book extremely useful for Cambodia. Not so much for hotel listings, etc., but for no-nonsense background information on Angkor, Phnomh Penh, and Siem Reap. The Vietnam portion was helpful as well, but I relied more on the Lonely Planet and Rough Guide Vietnam editions for that country. I would definitely recommend this book to someone traveling to Cambodia over the Lonely Planet edition, which is *really* outdated.

Output: Positive


Input: Consider Input: I bought this to go with my SD700IS because I wanted to keep it all oem and just as the one that came with the camera I have to admit I have never seen a battery last longer I have had the camera for almost 4 months now and between the 2 batteries I have only charged both 1 time and believe me I use my camera allot!


Output: Positive
