Fawcett (http://www.hpl.hp.com/techreports/2003/HPL-2003-4.pdf) discusses
multi-class ROC curves briefly and cites Hand, D. J., & Till, R. J. (2001).
A simple generalization of the area under the ROC curve to multiple class
classification problems. Machine Learning, 45 (2), 171–186. That might be a
good place to start.
