Example Input: A delightfully funny story! A wonderful graphic novel that gives us a cat's-eye view of the Sephardic Jewish community in Algeria and then the Algerian community in Paris in the early 20th Century. It's a love story. Very funny and endearing. And the hero is a cat! This is a must for Joann Sfar fans.
Example Output: Positive

Example Input: I was enchanted with this fascinating book on barn conversions. Barns are great relics from our past, conveying a sense of history, but many have been ruined by weather, time, and neglect. I didn't realize how many creative architects and owners have made barns useful for both residential and commercial use through renovation and restoration. The intrinsic character of these old barns brings an integrity and charm rarely seen in new construction. In many gorgeous illustrations, Rooney describes the history of barns, their adornment (who knew that it was all because of a 9th century pope that there are so many roosters on weathervanes?), and their use as gorgeous residences and fascinating commercial and establishments - including an architectural office, inns, and even a funeral chapel. One entrepreneur even used several to develop an office complex. If you love barns and if you like to see the past preserved in the present, you will love this book.
Example Output: Positive

Example Input: During travels to the Explorama Lodges twice, I was able to see what Dr. Smith has been able to accomplish. She is a marvelously dedicated individual. This books is a diary of her experiences, but after having visited the area, I was also able to have similar experiences from a tourist perspective. Dr. Smith, who I have met and talked to is a creative, stong and full person, dedicated to make a difference for the people in this area of the Amazon. She has done that and the book tells her story.
