Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Not worth of time and money.

This was the first book I had bought for my endeavor into the world of SOAP. Having read first few chapters it became quite apparent that either the author didn't have good knowledge about the subject matter or did a mediocre job to write this book in a hurry so that he can cash in on this craze of new technology. The sample codes are hard to comprehend meaning one may not understand the code at the first glance. The subject matter depicted in a inconsistent and incoherent manner. The book lacks any kind of structure.
