Abstract: In one embodiment, a method includes a computer server machine receiving information about a first media player event with the information about the first media player event including a viewing session identifier. Using a state machine, the computer server machine identifies a current state of the viewing session using the information about the first media player event. The computer server machine receives information about a second media player event. Using a state machine, the computer server machine identifies a subsequent state of the viewing session using the information about the second media player event. The computer server machine calculates metrics for the viewing session based on the current state and subsequent state, and stores the metrics. The computer server machine generates a session summary with the session summary including information about the metrics for the viewing session.

Abstract: Indexing and retrieving real time content in a social networking system is disclosed. A user-term index includes user-term partitions, each user-term partition comprising temporal databases. As a post is received from a user, a user identifier, a post identifier, and a post is extracted. An object store communicatively coupled to a temporal database for recently received content is queried to determine whether terms in the post has already been stored. A term identifier is stored in the user-term index with the user and post identifiers. A forward index stores the post by post identifier. Responsive to a search query, the user-term index is searched by the user's connections and the terms. A real time search engine compiles the results of the user-term index query and retrieves the stored posts from the forward index. The search results may then be ranked and cached before presentation to the searching user.

Abstract: Online systems, for example, social networking systems store features describing relations between entities represented in the online system. The information describing the features is represented as a graph. The online system maintains a cumulative feature graph and an incremental feature graph. Feature values based on recent user actions are stored in the incremental graph and feature values based on previous actions are stored in the cumulative graph. Periodically, the information stored in the incremental feature graph is merged with the information stored in the cumulative feature graph. The incremental graph is marked as inactive during the merge and information based on new user actions is stored in an active incremental feature graph. If a request for feature information is received, the feature information obtained from the cumulative feature graph, inactive incremental feature graph and the active incremental feature graph are combined to determine the feature information.

Abstract: In one embodiment, a method includes managing delivery of messages to non-stationary mobile clients. A computing system receives a request from a first user to send a message to a second user. The computing system then accesses the location information of the second user which includes the velocity of the mobile client of the second user. The computing system further accesses the activity information of the second user which indicates if the second user is currently active on a social-networking application. If the velocity indicates that the second user is non-stationary, the computing system then determines an activity-level of the second user. If the activity-level is below a threshold activity-level, the computing system confirms with the first user whether the message to the second user should be sent. If the activity-level is above a threshold activity-level, the computing system sends the message to the receiver.

Abstract: An online system allows online system users to search for and view content (e.g., videos) maintained in the online system. The online system may maintain user accounts associated with each user, which allow the online system to identify the users across different sessions within the online system. Upon receiving a request to present a video to a viewing user of the online system, the online system may present a content item in conjunction with the video, such that the content item overlays at least a portion of the video. The content item may be presented in conjunction with an interactive element corresponding to an option to receive a reminder associated with the content item. If the online system receives a request from the viewing user to receive the reminder associated with the content item, the online system may send the reminder to the viewing user at a later time.
