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: Enlightening description of immigration and languages . I started reading this wonderful book 6 months before I left Brazil towards Israel. After finishing the first Part (Paradise) I just could not keep on reading, and I abandoned the book for a while. After I landed in Israel I re-took the book and was delighted again with the realness of it. A thought occurred to me that the reading was so descriptive of the immigration sentiment that I just could not understand it before immigrating myself. The book helped me to understand and to organize the infinite sensations that come with the leaving/arriving to another country. How the language affects the way we think and act, how sadness and happiness are mingled into one strange feeling, how we cope and forget without noticing, and how we urge to succeed and prove that we can be part of the new country. In addition, the book also brought to me new feelings and curiosities about my grandparents, whom also escaped from Poland and Russia in the late 40's. Hoffman describes so well how the old traditions and languages influenced the new live of those who left their country because of prejudice and persecution! One passage that I am specially fond of: "No, I'm no patriot, nor was I ever allowed to be. And yet, the country of my childhood lives within me with a primacy that is a form of love. (...) All it has given me is the world, but that is enough. It has fed me language, perceptions, sounds, the human kind. It has given me the colors and the furrows of reality, my first loves. The absoluteness of those loves can never be recaptured: no geometry of the landscape, no haze in the air, will live in us as intensely as the landscapes that we saw as the first, and to which we gave ourselves wholly, without reservations." It reminds me of Wordsworth when he writes about Tintern Abbey. A wonderful life-changing book.
