This book makes a detailed examination of the critical problem of interestingness in data mining and knowledge discovery. The book surveys relevant work and proceeds to define a framework for measuring interestingness. The techniques discussed are applicable and transferable to real world data mining tasks where the volume of discovered knowledge is often large enough in itself to require further sorting. The book combines topical discussion, experimental evaluation and mathematical formalism in a concise and professional way. In addition, the relevant work of others is cited throughout. This book is well suited to data mining practitioners who develop/and or tweak their own algorithms and are looking to enhance their expertise in this area.
