Teacher: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Teacher: Now, understand the problem? If you are still confused, see the following example:
I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Reason: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this instance: A few years ago I bought a second hand copy of this book. During this time I must have read it at least once a year. I like it that much.It is a book about what humanity could aspire to become if we can put away the mistakes of the past and present.The arguments I've read that this is a unrealistic fantasy.... this is a book of fiction that portraits the thought and maybe the wishes of the author. You can agree with them or not.This is one of the few books that I would recommend to a beginning SF reader. It is not too difficult and a pleasure to read, and unlike many other books you are not left with a feeling of light depression because every main character died or had some other terrible fate happen to them.If you are interested in other works of Mr. Hogan I would recommend 'The Giant Novels' and 'The Genesis Machine'.
