Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Too many assumptions

I was disappointed with this book. Although it is structured reasonably well, the text often seems to assume prior knowledge - ie it talks about elements/actions as though the reader is already familiar with them.Then when you look up the reference in the index to see if there's clarification later on, the item cannot be found.As another reviewer says, there is much better information available both on the Internet and in other books.There's also a lot of irrelevant padding - like pages of quotes from the program developer about the......development of the program. As if it matters.I read it in a few hours and immediately put it up for sale. No takers so far.
