Detailed Instructions: 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.
See one example below:
Problem: 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
Explanation: 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'.

Problem: Too many cooks (even if they are good ones) spoil the broth . This book pulls together a lot of information, but in my opinion it is written and organized very very poorly. I have over 10 yrs of experience in in the healthcare industry and came across this book during a grad level course in CEA. Long, boring, convoluted sentences fill the pages of this book. It took about 3 times more time and effort to get through a page in this book compared to a page in respected journals like JAMA, NEJM, BMJ etc. If you have lots of time and are doing research in this field - go for it. Alternatively if you want to quickly determine what CEA is about, I would recommend reading Peter Muennig and Kamran Khan "Designing and Conducting Cost-Effectiveness Analyses in Medicine and Health Care"
Solution:
NEG
