  • [2020-02-24]: We are hosting Social Media Prediction Challenge 2020.


Continuing the series of Social Media Prediction (SMP) Challenges, the 2020 edition is seeking excellent research teams to provide new ways of forecasting problems and meaningfully improve people’s social lives and business scenarios. Temporal Popularity Prediction is a massive-scale, multimodal and time-series forecasting problem that is central to various scenarios, such as online advertising, social recommendation, demand forecasting, etc. We released a large-scale Social Media Prediction Dataset (SMPD) with over 486K posts, 70K users and rich information including user profiles, images, texts, times, locations, and categories. This year the challenge will be again hosted by the joint team from multiple research organizations.

Dataset Statistics

The SMPD (Social Media Prediction Dataset) contains 486K social multimedia posts from 70K users and various social media information including anonymized photo-sharing records, user profile, web image, text, time, location, category, etc. SMPD is a multi-faced, large-scale, temporal web data collection, which collected from Flickr (one of the largest photo-sharing platforms). For the time-series forecasting task, we split training/testing data into chronological sets (commonly, by date and time). The tables below show the statistics of the dataset.
