Abstract
A content recommendation system includes a processor and a memory coupled to the processor. The memory stores instructions that, upon execution, cause the processor to obtain a first viewing history of a first user from the viewing history index. The instructions include determining, based on the user similarity index, a first set of users similar to the first user. The instructions include obtaining a corresponding viewing history from the viewing history index and selecting a set of similar content item identifiers based on similarity scores. The instructions include updating a first recommendation list with (i) the corresponding viewing history for each similar user in the first set of users and (ii) the set of similar content item identifiers. The instructions include selecting and transmitting to a user device a subset of recommended content item identifiers from the first recommendation list.
