Abstract
A relevance model is used to process an inventory of updates for a member of an on-line social network in order to select a subset of updates for presentation to the member. One of the features used as input to the relevance model is viewer affinity. The viewer affinity indicates preference of a member for a particular type or source of information and is determined using the estimated probability of the member clicking on the impression of an update and also based on a correction variable. The correction variable is generated based on information regarding previously-observed interactions of the member with the updates.
