Example Input: Awful book on its own for complete beginner . I wanted to teach my son to program and chose VB and this book.  This book really "looks" great but I'm not impressed by the content. So much so that it compelled me to write my first ever book review.    The introduction "Who Is This Book For?" gives a sense that this book can get people into programming.   I would be amazed however if anyone not familiar with programming will get past Chapter 1 without being frightened by the whole prospect of programming.  Chapter 1 initially jumps into some Microsoft marketing of .Net which really adds nothing but confuses the readers by having to deal with line after line of computer jargon.  Then the chapter gives a horrible overview of Object Orientation which again doesn't help later.    I feel the whole book is like the first chapter. Doesn't give you some of the basics but rambles about more complex stuff you don't need between some hands on practical stuff.     I actually thought the first example was really poor also.  I am of the opinion that someone typing something in themselves and seeing it work should be rewarding.  The example however was hard for a novice as it had long lines of comments and the line to print the variables was a minefield of quotes and symbols making it pretty likely that a beginner would do a typo.      The title of the book is "Build a Program Now!".  This the book does and given how complex setting up an environment it is helpful.  But I've slammed the rating of this book because this could have covered with a lot less pages and maybe substitute some of the drivel with a little about the syntax of VB or even some explanation of the example code.    DON'T buy this book if you think it will teach you anything about computing or programming.    DO buy this book if you have some other teaching reference for Visual Basic and want something that will help you setup your build environment.  Also comes with a VB Express CD so you don't have to downloaded it.
Example Output: NEG

Example Input: Stay Clear of Lonely Planet . A hopeless mess of headlines and confusing comments, very little structure.  No rankings of what you should see and do, no pictures, no useful restaurant and hotel recommendations.  Endless yatter about nothing makes this a boring read with almost no real content.  Absolutely worthless on our Japan trip to Tokyo and Kyoto.  This is not the first time we have been disappointed by Lonely Planet. They cater to backpackers only, usually looking for the cheapest accomodation and meals, and with no value added for the traveller who is short on time but still wants to make the most out of his/her time.  We ended up buying the Eyewitness Guoide which is fast and easy to use.
Example Output: NEG

Example Input: A step back . I have been reading this book for a graduate level Art Education course.  In this book Kochman makes many broad generalizations that, while he may consider them true, are belied by the way he phrases them.  He makes many  absolute statements about the behaviors of both black people and white  people and the way in which he writes leaves no room for deviation.  I  would recommend this book if you are curious about why racism is still a  problem in this country.  The problem of racism will only begin to be  alleviated when people stop making broad statements that stereotype races  or cultures as behaving in a particular way.  Kochman does not seem to  realize this
Example Output:
NEG
