Welcome to the KDD Cup 2012!
As you know, every year the KDD Cup attracts the most brilliant minds throughout the world to converge on challenging data mining problems. This year is no exception! The 2012 KDD Cup welcomes data miners to compete on the largest real datasets ever released publicly for competitions. Fresh from Tencent, the data mining tasks are about recommendation prediction in social networks and social media, and about user click modeling in advertising. We hope that these tasks would challenge your intelligence and push the limits of data-mining capabilities.
From Tencent, we encourage you to use these data fully for your algorithmic innovations and computational discoveries, and make breakthrough discoveries in science and industrial problems.
I hope you enjoy the competition, and wish you a great success!
