KDD Cup 2012 (Track 2): Predict the click-through rate of ads given the query and user information

Search advertising has been one of the major revenue sources of the Internet industry for years.

In this task, given the training instances derived from session logs of the Tencent proprietary search engine,, participants are expected to accurately predict the pCTR of ads in the testing instances.
