From the reviews: "The book looks at three major types of preference learning: label ranking, instance ranking, and object ranking. ... chapters contain case studies and actual experiments to illustrate the claims made within. ... this is a useful book in an emerging and important area, and hence would be of interest to machine learning researchers. The book is quite readable to that audience, despite a heavy emphasis on formal treatment." (M. Sasikumar, ACM Computing Reviews, September, 2011)
