This year we will focus on the task Headline Popularity Prediction. Meanwhile, we are open for innovative self-proposed topics. The contestants are asked to develop their prediction algorithm based on the SMHP dataset provided by the Challenge (as training data), plus possibly additional public/private data, to address one or both of the given tasks. For the evaluation purpose, a contesting system is asked to produce prediction results of popularity. The accuracy will be evaluated by pre-defined quantitative evaluation. The contestants need to introduce their algorithms and datasets in the conference.
