How TikTok's "algorithm" works is pretty obvious if you've spent any time on there. It learns what you like by how much of a video you watch and how you interact with it, and it establishes some kind of weighted feature vector based on hashtags used in the description, words used in the comments, text drawn on the video, audio background, possibly some audio transcription of words said, if you commented on it, if you forwarded it to a friend, and so on. There may be some network based recommendations, based on who you follow but those seem to be weighted very weakly, and that makes sense if you're trying to keep the platform from getting botted. It also seems to do some non-dominant sorting to keep from only showing you things from the same type of video. Facebook's competing short video service is terrible in comparison. It only wants to show me Trevor Noah clips, and things tangentially related to things I may have "Liked" 12 years ago.
