KDD Cup is the first and the oldest data mining competition, and is an integral part of the annual ACM SIGKDD International Conference on Knowledge Discovery and Data Mining (KDD). This year's KDD Cup will be related to (but different from) the current Netflix Prize competition ( http://www.netflixprize.com/). There will also be a workshop at the KDD-07 conference, where the participants of both the KDD Cup and the current Netflix Prize competition will present their papers and exchange ideas.

There are 2 parallel options for participating:*

1. The KDD Cup competition (open to all)
2. Workshop paper submissions (open to Netflix prize participants only)

Full details are provided at the KDD Cup and Workshop 2007 website:
