A method for creating personalized and continuous playlists for a content sharing platform based on user history is disclosed. The method includes grouping content items into groups based on whether users access the content items close together in time and whether the content items appear together in search results and are both selected by the users, the groupings representing a relatedness between pairs of the content items, determining probabilities that the users transition between the groups when viewing the content items, assigning, for a user of the users, a score to each group in a subset of the groups, wherein the scores represents preferences of the user for viewing the content items of the subset, selecting, for the user, a group in the subset based on the assigned scores and the probabilities, and providing a content item from the selected group to include in a playlist generated for the user. |
