Example Input: This book preaches a very right wing kind of economics. If you can imagine one of Rush Limbaugh's readers or helpers writing a primer on economics, then this is it. Keep government small etc. The author most likely was an Austrian school follower. As it is avaiable free on Limewire, maybe get a free copy on the Net or browse it in your local library. No need to buy unless you want to flesh out (sic) the ideas of Mr Limbaugh et al. The book relentlessly hammers home the ideas that government should be amall, self interest drives the economy forward and that state intervention is bad.
Example Output: Negative

Example Input: This 1991 Muse Records CD (out of print)is among Earlands weakest B-3 performances recorded. Standard tunes like "Unforgetable" and "Europe" (yes, the Santana hit) is arranged and played like elevator music and goes nowhere...But there are moments where Earland shines and cook's predictable with his combo like on "Sheila" and "Kicker", but thats all. Even Earland's sidemen like Eric Alexander on tenorsax does not lift the overall performance quality. Thia is not capured misic, this manufactured music. For Earland collectors - put this CD in your shelf and start looking for Earlands recordings on Prestige, Milestone and Savant/HighNote
Example Output: Negative

Example Input: This was such a beautiful film. Breathtaking! The best part was watching it with my movie buddy Sandra Zhao! I cannot wait to see it again. I truly felt like the movie had taken me on a trip to Denmark. I have still not watched the Lives of Other's which beat Pan's Labyrinth and this movie for Best Foreign Film. Can't wait to see it.
