TASK DEFINITION: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
PROBLEM: I received the message that the U. S. government is hiding knowledge about what is beyond Earth's atmosphere. But all governments hide information from the masses of their people. What intrigued me was when the Sentinel Prime character said to the Optimus Prime character that they used to be gods and now they were called machines. I can relate to that statement. I am a descendant of a people that were performing high sciences at one point in time and now we are beasts of burden. Try to talk to a typical African person about science and see what you get. At best they'll say, how does this help me pay my bills? At worse they'll look at you like you have 2 heads.

SOLUTION: Positive

PROBLEM: I guess you have to be a romance novel lover for this one, and not a very discerning one. All others beware! It is absolute drivel. I figured I was in trouble when a typo is prominently featured on the back cover, but the first page of the book removed all doubt. Wait - maybe I'm missing the point. A quick re-read of the beginning now makes it clear. This has to be an intentional churning of over-heated prose for satiric purposes. Phew, so glad I didn't waste $10.95 after all.

SOLUTION: Negative

PROBLEM: This technology module contains a brief introductory description to the exchanger type above, followed by information on construction, construction materials, operating limitsand principal applications. Where appropriate, a comparison is made with conventionalshell and tube heat exchangers to emphasise size and weight reductions that can beachieved by using compact heat exchangers.The Module 3 series present further information applicable to all technologies, such asgeneral advantages and limitations of compact exchanger designs, common applications,fouling and how to minimise it, energy efficiency. heat transfer enhancement, exchangerselection, specification and operation, process intensification and software programmes.

SOLUTION:
Positive
