Winston is one of the VERY BEST at explaining complex technological and scientific concepts and his books are always well worth reading. I am not in my office as I write this, or I'd give you better citations on both this and the Winston book. It describes techniques, approaches, and applications. Moreover, Greg and others also operate an internet mailing list to connect KDD people for cross-polenation of ideas. I hope the above has been helpful.
