In this task, you are given books product reviews in Japanese 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.

Example Input: Different and effective . The book follows the kanji of the chapters, but instead of flooding you with all of the kanji from the unit, it gives you the most important, building your ability. There are a variety of activities as well. What impresses me about the book is that, while it does its own system, it definitely gives you essential kanji and kanji combinations (!) that I haven't found in other books. Very cool. I used this book (in addition to the other books in the first set) to prepare for the JPLT Level 3. The structure is totally different from the test, but I was pleasantly surprised how well prepared I was. Definitely worth owning.
Example Output: POS

Example Output: POS
