## Abstract

Some embodiments provide a program that receives from a client device a request for data feed items relevant to a user, determines a set of categories associated with the user, and queries a database for a first set of data feed items specify the user as a recipient of the data feed item. The program retrieves a second set of data feed items from an external content provider. The program modifies relevance scores of the first set of data feed items and the second set of data feed items based on the set of categories associated with the user and a set of factors, generates a result set of data feed items comprising the first and second sets of data feed items ordered based on the modified relevancy scores from highest relevancy score to lowest relevancy score, and provides the result set of data feed items to the client device.
