Example Input: This is Bernie Taupin's second solo album and it is excellent.From the rockers Born on the fourth of July to his smooth ballads Venezuela and Love(the barren desert). This is a great album for anyone who has followed Elton and Bernie's career.
Example Output: Positive

Example Input: While this is a fairly well written book anyone that has ever been connected to Manson, Manson's followers, or the Manson case has said there was no way that Charles Manson had ANYTHING to do with this book.First of all, Manson, while speaking makes NO sense whatsoever.Secondly, If anyone has ever seen Manson's written word, not only does it not make any sense, but it's not legible.Third, The "frame" that the wording is in, does not sound like anything I have ever seen, read, or heard from Manson.Fourth, Manson himself has denied having anything to do with this book since it was being written, through publication, through all the years since.Some of the information in this book is factual, based upon trial transcripts, and conversations that are documented elsewhere. However the words that are attributed to Manson, in my opinion were the author's own words. Not a bad read, but not something I would recommend to someone looking for the 'truth'.
Example Output:
Negative
