Ex Input:
No much change . Although this book has been written almost 50 years ago it still provides basic insight into our behavior in the modern world. 'Money, prestige and power are the main incentives today for the largest section of our population - that which is employed'. This probably holds still today whereas some of the major concerns of the fifties are not concerning people any more.  A book to read and think about

Ex Output:
POS


Ex Input:
Needs Editing . This is a fast-paced book with all the formulaic elements required of a political thriller. Nothing here particularly surprised me. I would guess that if you have enjoyed Mr. Flynn's other works you will enjoy this one as well.    Mr. Flynn needs a more assertive editor. His use of language is so sloppy as to distract a reasonably sensitive reader from the finer points of the story. This probably isn't detrimental to the reader's comprehension, but it is irritatng.    Finally, one very minor quibble: non-standard spellings are used throughout (such as "harken" rather than "hearken"). This may or may not matter to any given reader, but I found it to be worthy of mention

Ex Output:
NEG


Ex Input:
A GREAT BOOK! . I have been waiting days for this book, and it finally came today. Honestly, I expected it to have your standard sword exercises and cuts, but it contains stances and techniques that I have never even heard of, while some are familiar to me. Thanks to having a hardwood bokuto (which I also purchased off of this website), I can now incorporate new exercises into my practice. Even though Hatsumi-Sensei is a ninja, he is well-versed in the culture of the samurai and the sword as well. I recommend it to all aspiring swordsmen

Ex Output:

POS
