Well, it's another year, and that means there is another opportunity to take part in one of the biggest data mining competitions held every year -- the KDD Cup, which is a part of the ACM SIGKDD conference. (FYI, KDD-2011 is in San Diego this year, August 21-24.) This year, the competition is based on analyzing music ratings from users of Yahoo! Music. The challenge is to analyze the ratings and find information about how songs are grouped, how hidden patterns link various albums together, which artists complement each other, and so on. The ultimate goal here is to develop a classifier that can analyze a user's music ratings, and come up with the best suggestions on which songs users would like to listen to next.
So, where does "data mining" come in? The data consist of 300 million ratings performed by over 1 million anonymized users. The ratings are given to different types of items-songs, albums, artists, genres-all tied together within a known taxonomy.
The prize:
- 1st place: $5,000
- 2nd place: $2,000
- 3rd place: $1,000
(Yes, this is a bit less money than the Netflix prize a few years ago!)
Good luck!
