   KDD-Cup 2011

   Recommending Music Items based on the Yahoo! Music Dataset
Website:  <>

Call for Participation:

People have been fascinated by music since the dawn of humanity. A wide
variety of music genres and styles has evolved, reflecting diversity in
personalities, cultures and age groups. It comes as no surprise that human
tastes in music are remarkably diverse, as nicely exhibited by the famous
quotation: "We don't like their sound, and guitar music is on the way out"
(Decca Recording Co. rejecting the Beatles, 1962).

Yahoo! Music has amassed billions of user ratings for musical pieces. When
properly analyzed, the raw ratings encode information on how songs are
grouped, which hidden patterns link various albums, which artists complement
each other, and above all, which songs users would like to listen to.  Such
an exciting analysis introduces new scientific challenges. The KDD Cup
contest releases over 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 competition is divided into two tracks:
The first track is aimed at predicting scores that users gave to various
The second track requires separation of loved songs from other songs. Both
tracks are open to all research groups in academia and industry.
