<h2 class="p-title"><b>Task</b></h2>
<p class="p-body"><b class="orange">Social Media Popularity Prediction</b>. The overconsumption of online information has its limitations, so online word-of-mouth helps us to efficiently discover emerging topics, interesting news, or new products from the information ocean. Therefore, predicting online popularity became a crucial task for online media, brand owners, social influencers, and individuals.</p>
<p class="p-body">The task focuses on predicting the impact of sharing different posts for a publisher on social media. Given a multimodal post from a publisher, the goal is to automatically predict the future popularity after the post is publicly shared.</p>
