Teacher: In this task, you are given books product reviews in English language. The goal is to classify the review as "POS" if the overall sentiment of the review is positive or as "NEG" if the overall sentiment of the review is negative.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Hopeful for those who seek harmony in the world . I wouldn't recommend this to anyone who thinks that religious wars, repression of individual spirits or rape of the earth are good things. Those who seek peace, harmony, celebration of each of us and respect for our earth will find this hopeful
Solution: POS
Reason: The overall sentiment of the review is positive as the reviewer mentions positive expressions such as 'hopeful', 'will find this helpful' etc.. Hence, the label is 'POS'.

Now, solve this instance: The book was as empty as the chair. . New York criminalist, Lincoln Rhyme, is in North Carolina to undergo surgery which he hopes will improve his quadriplegia. A sheriff from the small town of Tanners Corner asks for his help. A teenaged boy has been murdered and two young women kidnapped by a youth known as Insect Boy. Rhyme, along with his protagee' and soul mate Amelia Sachs and his aide Thom, agree to help. This is the first book by Deaver I've read and, while I am hoping it was just a bad choice, I'm not certain I'll read another. I really struggled to get through it. I had no history of the principal characters and none was given. In fact, all the characters were one dimensional, there were two many of them and stereotypes ran rampant. I like a good twist or two in a story but this became laughable. And let's not even talk about the ending! I did feel Deaver did a very good job conveying the problems and frustrations of a quadriplegic, but that was the only redeeming feature. As for the plot, the title says it all. This rated zero on the believability scale.
Student:
NEG
