"…it has to be noted that this book is an excellent resource for conducting Web mining lectures or single units within Data mining class. The data can be used for small as well as quite comprehensive business intelligence projects. The book's content is easy to access; even students with very basic statistical skills can get the flavor of the intriguing aspects of Web mining." (Journal of Statistical Software, April 2008)

"…highlight[s] the exciting research related to data mining the Web…a detailed summary of the current state of the art." (CHOICE, December 2007)

"I can say I really enjoyed reading this book…a great educational resource for students and teachers." (Information Retrieval, 2008)
