Example Input: Interesting history... . This was an interesting read.  Napolitano is a Fox News Contributor who is an advocate of interpreting via natural law and reading the Constitution literally for it's intended meaning.  As a result, the Fox News bashers will tend to ignore the book but it's worthy of their attention too because the leftwing liberal idea of reinterpeting the Constitution for today is what lead to legislation like the Patriot Act.  In an unbiased way (politically), his criticisms of the current administration are well-balanced with a good explanation and examples of abuse.  I've traditionally been a supporter of the Republicans and the Patriot act but the Judge's book have made me rethink the Patriot Act.  I was also surprised at how far back in time some of the interpretation contraversies go, some dating back to Hamilton and Jefferson themselves
Example Output: POS

Example Input: Not for the beginner. . I went to the same school as the author of this book, and so it was used for my introductory CMOS design class.  The book has a lot of great material, but it was rather confusing to me as a beginner.  Now that I'm a more seasoned designer, I can look back on this book as an excellent reference, but I STILL find the explanations somewhat confusing.  It's clear that the author is a foremost expert on the subject, but he just has some trouble relaying the fundamentals to the novice designer
Example Output: NEG

Example Input: The Great War in Retrospect . There are many reasons why World War I has been labeled THE GREAT WAR: it was the war to end all wars in the minds of those who lived through it, who were directly and indirectly affected by it, who continue to reference it as the war with the most emotional cost.  In times when wars seems to constantly queue since that inception of world war, wars spreading  from WW II, through Korea, Vietnam, the Gulf, Balkans, Eastern Europe, Spain, Africa, Iraq, Afghanistan, South America and on, taking a long hard look at the Great War will hopefully center our attention on a past time that can be analyzed and from which we can hopefully learn.    Now that Jay Winters' brilliant book 'Sites of Memory, Sites of Mourning : The Great War in European Cultural History' is available/affordable in paperback, every household should have a copy as children grow into the years of this century.  Winters' examination of the devastation of WW I and the ways in which it informed all of the arts, the architecture, the literature, films, memorials - the people of the globe - is a mighty assignment  and he is more than successful in humanizing his message.  This book overflows with photographs of places, faces, bodies alive and dead, paintings, sculptures, film stills - each of which drives home Winters' powerful message.    Sad though it may be to admit, war is a part of life on this abused planet: the more we study it the more we hopefully will reduce it.  Winters wants to make sure that we remember, that we read, view, walk through, see, hear, and listen to the remnants the Great War left behind.  This is a powerful, necessary book and should be required reading and viewing for us all.  Highly recommended.  Grady Harp, August 0
