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'.

OK. solve this:
Great articles on defining and teaching about leadership . The wide variety of articles on leadership covers well items from the basic topics such as the difference between managers and leaders to how someone can be both (and the tensions that can cause!). Two of the best articles were on how leaders really spend their time during the day and how leaders foster an environment in which other people can also be identified and brought forward as leaders. I would've rated this five stars, but there are a couple of articles (on 'defining moments' and CEOs) that weren't a complete waste of time but seemed too far divorced from the typical leader within a company that I was surprised the HBR didn't find something more likely to be widely applicable to fill the space
Answer:
POS
