Teacher: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Teacher: Now, understand the problem? If you are still confused, see the following example:
I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Reason: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this instance: Having heard the author speak on the radio, her works praised highly by the host, I decided to start with the first of the Monk series. Unfortunately, I found the main character thoroughly unsympathetic and unlikable. The story was slow as molasses with bits and pieces of useless information thrown in to fatten the book. Also, I don't know the clinical features of amnesia, but it seemed that Monk's memory loss was selective and inconsistent. The ending was highly anti-climactic and the fate of the characters in question never revealed. I was very much looking forward to reading her books, but was sorely disappointed.
Student:
