The requested video item comprises a plurality of portions, each associated with a corresponding additional content item. The method further includes responsive to the media player beginning to playback a first portion of the requested video item, causing the second GUI portion to display a corresponding additional content item without an interaction of the user, and in response to a user selection of an additional content item in the third GUI portion, automatically updating playback of the video item to correspond to the selected additional content item.

Abstract: A system includes an ingestion component configured to receive a request from an entity for content related to a content item and a user identity. The request has a content identifier representative of the content item and a token. A request processing component of the system is configured to access a database associated with the system and identify the content item and the user identity using the content identifier and the token, wherein the database has information associating the token with the user identity and associating the content identifier with the content item. In response to identification of the content item and the user identity, the request processing component directs a recommendation engine associated with the system to identify the content related to the content item and the user identity. Information identifying the content related to the content item and the user identity is then transmitted back to the entity.

Abstract: An online system determines a client device associated with a user that is to receive a new notification. The client device presents the notification and receives an input to forward the notification to a different client device and/or a different application. The client device sends a request to the online system to forward the notification. The online system determines a list of available client devices and/or available applications that are able to receive a forwarded version of the notification and provides the list to the client device for selection. Upon receiving a selection, the client device sends the selection to the online system which generates the forward notification that is appropriate for the selected client device and/or selected application. Thus, the online system avoids over-notifying a user, while also enabling the user to consume the content of the notification according to his/her preferences.

Abstract: Systems and methods for providing third-party content can include a data processing system receiving criteria defining online activities of an online activity type related to a product or service context from a computing device of a third-party content provider. The data processing system can identify a cluster of client devices based on the defined online activities, and determine a subset of keywords associated with the defined online activities and the identified cluster of client devices. The data processing system can determine a performance metric of the subset of keywords based on the cluster of client devices, and provide the subset of keywords and the performance metric to the computing device. The data processing system can receive from the computing device a parameter value of a first keyword of the subset of keywords to use in selecting content items of the third-party content provider associated with the first keyword.

Abstract: A method for presenting content items includes receiving, by a user device, a request for a media content item hosted by a content sharing platform, and providing, by the user device, a graphical user interface (GUI) comprising a first GUI portion having a first media player to play the requested media content item, and a second GUI portion having a second media player to play an additional media content item associated with a particular portion of the requested media content item. The method further includes in response to the first media player beginning to play the particular portion of the requested media content item, causing the second media player to play the additional media content item.

Abstract: Systems and methods of a gain adjustment component for content selection infrastructure are provided. The system can receive a selection of multiple topics identified by a semantic analysis technique, and identify one or more keywords.
