I am grateful to the DiSC associate editors for their timely help. I would also like to thank the VLDB endowment, the IEEE, the SIGKDD, and in general all the organizers and program chairs who gave us the permission to include the contents of the conference and workshop proceedings featured in DiSC '02. At the ACM, I would like to thank Deborah Cotton for her logistic help.
I gratefully acknowledge the ACM for providing partial financial support to DiSC. Aidong Zhang
