A social networking system includes pages created by users for providing content related to topics of interest. An interaction engine captures data and maintains analytical information about how users interact with pages and posts. When a user takes an action such as liking a page or a post, the interaction engine updates the page's activity history to reflect the activity and information about the user who took the action. The interaction engine also measures the reach of pages and posts, by determining how and from where each user viewed the page and its contents. The interaction engine further tracks the community's interest in pages and posts by determining how many unique users create stories that include a page or its content. An insights module uses the data obtained by the interaction engine to synthesize graphical reports about page interactions and present the reports to page administrators.

Measuring page viewership in a social network

A system determines a set of users satisfying a given criteria based on attribute values of the users. The system associates each value of an attribute with a representation of users having that attribute value. The representation of users may be an enumeration of users or a bit index. The system receives a request for determining a set of users satisfying a given criterion. The system identifies a logical operation based on the criterion and performs the logical operation to determine the set of users. The representation of the set of users may be distributed across a plurality of processors, allowing the system to perform the logical operation in parallel. The system may further determine statistical information describing a characteristic of the set of users, for example, page likes by the set of users. The statistical information may be presented to a business for analyzing their target audience.

Querying groups of users based on user attributes for social analytics

Systems and methods for performing near real-time merging of distributed data streams are described. For example, streams of ad impressions, ad clicks, and conversions are sorted by user id into virtual buckets. The buckets of data are distributed across multiple servers, so that each server can process their respective buckets of data independently. Each server uses synchronization logic to determine a running delay distribution of the data streams. Based on the delay distributions, merge processing of the streams is appropriately delayed to ensure that the ad impression and ad click stream information needed for correlating with the conversion stream information is likely to be available in real time.
