You will be given a definition of a task first, then some input of the task.
Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

I bought this book after i failed to get the score i needed in the TOEFL exam, and it helped me a lot at the second time I did the test. The best part about it is the CD-ROM that has 4 complete tests so you can practice just like if you were doing the real Computer Based TOEFL Test. It helps you to get in the mood of the test so you are prepared when you take the real test. There is only one thing that should be enhanced in this book. The review and hints at the "writing test part" are not enough. There should be more essay examples. Over all, this is the book you have to buy if you are planning to pay just for one book to prepare for the TOEFL
Output:
Positive
