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: Who is this about? . I bought and read this book for a class and found it very difficult to take much away from. The accounts are potentially very enlightening, but the author's writing style obfuscates their values. Her interjection of her own personal stories into the work was sloppy and often left me unsure of who I was reading about. While I don't know of any other book which tells these stories, there are many other books that contain similar accounts which are far more effective
Student:
NEG
