Example Input: Definitive...a wonderful addition to my library . I purchased this book when it first came out. I thoroughly enjoyed it at that time, and have used it as a reference ever since. What so many do not realize is that different treatments (distillation vs. tincture vs. absolute vs. hydrosol, etc.) of a plant result in often VERY different properties comprising that substance. So finally having some insights into the properties of hydrosols, the water remaining from the distillation of a plant, is/was much needed. No other work like it had been available. And what a revelation about many of them. Most people, even those working with essential oils and their cousins were not aware of what this or that hydrosol might do, let alone how to get their hands on it. Really needed and really wonderful work
Example Output: POS

Example Input: Don't buy this book! . If you're going to read one of the great classics of literature-and you should-don't pick up this edition. It is a reprint of a version that dates back to the 1870s and was exposed more than 40 years ago for cutting nearly one-quarter of Verne's story and mistranslating much of the remainder. Its reappearance in this edition is all the more amazing considering Tor's status as a leading science fiction publisher, and the company's willingness to perpetrate this fraud on is many readers is truly stunning. If you want to truly get to know Verne's novel, pick up the elegant Naval Institute Press edition, in a modern, complete, updated translation, with commentary by the leading American Verne expert today, Walter James Miller. That book also comes with many of the artistic engravings that illustrated the original French first edition (no illustrations are to be found in the B&N Mercier reprint). Less attractive but more academic is the Oxford Classics version of Twenty Thousand Leagues. This review is posted on behalf of the North American Jules Verne Society by Jean-Michel Margot, president NAJVS
Example Output: NEG

Then, she is forced to go to a public school. The family has to sell some of their land to pay for Mama's treatments. Ida B has a difficult time coping with this, but thanks to her teacher she turned back to the same Ida B.
