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.

Let me give you an 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
The answer to this example can be: POS
Here is why: 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'.

Save Your Money . Brian Hinton's Both Sides Now is a complete disaster. What could have been a promising biography of Mitchell is instead a garbled mess. Indeed, Hinton's text is relatively void of biographical information. Rather, Hinton relies on a handfull of interviews published of Mitchell's, and he quotes from them in such large chunks that the reader would be the wiser to check out the interviews from their sources. Following a brief, and flawed, biographical section, Hinton uses the rest of the text as a forum for his interpretations of Mitchell's work. Album by album, song by song, Hinton gives his own personal commentary on Mitchell's music so that the text ends up reading like a diary of Hinton's own personal reflections. Moreover, Hinton's analysis of Mitchell's songs are sometimes so off-base and confusing that the reader is left wondering how he comes to these conclusions. Finally, his constant personal comments in the text make it seen like nothing more than a high school writing assignment
Answer:
NEG
