SMP Challenge: An Overview of Social Media Prediction Challenge 2019
This addresses the need for better predictive analytics in social media for applications like recommendation and advertising, but it is incremental as it focuses on defining a new challenge and dataset rather than proposing a novel method.
The paper introduces the SMP Challenge 2019, which tackles the problem of predicting future popularity of social media posts before they are uploaded, using a novel task called Temporal Popularity Prediction, and releases a large-scale dataset with over 480K posts from 69K users.
"SMP Challenge" aims to discover novel prediction tasks for numerous data on social multimedia and seek excellent research teams. Making predictions via social multimedia data (e.g. photos, videos or news) is not only helps us to make better strategic decisions for the future, but also explores advanced predictive learning and analytic methods on various problems and scenarios, such as multimedia recommendation, advertising system, fashion analysis etc. In the SMP Challenge at ACM Multimedia 2019, we introduce a novel prediction task Temporal Popularity Prediction, which focuses on predicting future interaction or attractiveness (in terms of clicks, views or likes etc.) of new online posts in social media feeds before uploading. We also collected and released a large-scale SMPD benchmark with over 480K posts from 69K users. In this paper, we define the challenge problem, give an overview of the dataset, present statistics of rich information for data and annotation and design the accuracy and correlation evaluation metrics for temporal popularity prediction to the challenge.
