• Abstract summary: We analyze user engagement on TikTok using data we collect via a data donation system. We find that the average daily usage time increases over the users' lifetime while the user attention remains stable at around 45%. We also find that users like more videos uploaded by people they follow than those recommended by people they do not follow.

• Abstract: Short-format videos have exploded on platforms like TikTok, Instagram, and YouTube. Despite this, the research community lacks large-scale empirical studies into how people engage with short-format videos and the role of recommendation systems that offer endless streams of such content. In this work, we analyze user engagement on TikTok using data we collect via a data donation system that allows TikTok users to donate their data. We recruited 347 TikTok users and collected 9.2M TikTok video recommendations they received. By analyzing user engagement, we find that the average daily usage time increases over the users' lifetime while the user attention remains stable at around 45%. We also find that users like more videos uploaded by people they follow than those recommended by people they do not follow. Our study offers valuable insights into how users engage with short-format videos on TikTok and lessons learned from designing a data donation system.

  We study if one can effectively diagnose behavioral addiction using digital data traces from social media platforms. We survey 1590 TikTok users and stratify them into three addiction groups. By analyzing users' data, we find that highly likely addicted users spend more time watching TikTok videos and keep coming back to TikTok throughout the day.

  We propose a hybrid filtering based MIcro-video haSHtag recommendatiON MISHON technique to recommend hashtags for microvideos. Since hashtags reflect users topical interests, we find similar users based on historical tagging behavior to model user relatedness. We also propose a content and social influence based technique to model the relatedness of cold start users with influential users.

  Despite the importance of TikTok's algorithm to the platform's success and content distribution, little work has been done on the empirical analysis of the algorithm. Using a sock-puppet audit methodology with a custom algorithm developed by us, we tested and analysed the effect of the language and location used to access TikTok. We identify that the follow-feature has the strongest influence, followed by the like-feature and video view rate.
