Abstract: An online services system provides monitoring of user interaction with third-party content. The monitoring is performed by a script in a web page provided by the online services system, which script provides a timer invoked when the browser leaves the online services system's page for a page comprising third party content. When the online services system serves the page, the browser reads the HTML to render the page, including the script with the timer. When the user leaves the online services system page, the timer begins, and when the browser returns to a page provided by the online services system, the timer ends and duration information from the timer is provided to the online services system. Applications include measurement of the quality of interaction between users and a third party advertisers, in which time spent viewing third party content is a proxy for the quality of the interaction.

A crop window is automatically determined for the source content item based on framing criteria. A cropped media asset is automatically generated based on the source content item and the crop window.

Abstract: Exemplary embodiments relate to improvements to neural networks for translation and other sequence-to-sequence tasks. A convolutional neural network may include multiple blocks, each having a convolution layer and gated linear units; gating may determine what information passes through to the next block level. Residual connections, which add the input of a block back to its output, may be applied around each block. Further, an attention may be applied to determine which word is most relevant to translate next. By applying repeated passes of the attention to multiple layers of the decoder, the decoder is able to work on the entire structure of a sentence at once (with no temporal dependency). In addition to better accuracy, this configuration is better at capturing long-range dependencies, better models the hierarchical syntax structure of a sentence, and is highly parallelizable and thus faster to run on hardware.

Abstract: A method and system for populating identities in a message service involves registering a user of a first messaging service with a second messaging service. User identities for users other than the registered user may be identified. These user identities may be associated with the first messaging service and may be stored in a list associated with the registered user. It is determined if each identified user identity has a matching user identity associated with the second messaging service. If so, a database associated with the second messaging service is populated with the matching user identities. Determining whether a matching user identity exists may be performed, for example, by making character strings comparisons between user identities or using a database that stores a mapping of first messaging service user identities to second messaging service user identities. The mapping database may be generated as corresponding user identities are discovered.

Abstract: An online system identifies articles containing factual reporting and information associated with the articles (e.g., authors, publishers, distributors, content, etc.). The online system extracts embeddings for the articles based on the information associated with the articles and generates nodes of a graph, in which each node corresponds to an article or information associated with an article. The online system then identifies relationships among the nodes using the embeddings and generates additional nodes of the graph indicating these relationships. Each of the additional nodes may correspond to any type of information that may be associated with an article. The online system may query the graph for information identifying publishers that published articles alleging a fact, information identifying articles containing editorialized content or clickbait, etc. or to identify and remove similar articles from a feed to be presented to an online system user, to highlight contradicting articles in the feed, etc.

Abstract: An online system predicts a performance of a content item campaign based on a set of received target parameters from a content item publisher and compares the predicted performance of the content item campaign to predicted performances of comparison campaigns. The comparison campaigns are selected by performing a plurality of simulations on prior content item campaigns to estimate campaign presentation results for each prior content item campaign if presented to users with the sets of test campaign parameters. After generating histograms based on the estimated results, the online system selects prior content item campaigns for the set of comparison campaigns based on changes in histogram positions of the prior content item campaigns. The online system generates a set of estimated campaign presentation results for the content item campaign and the set of comparison campaigns for comparison.

Abstract: A virtual reality (VR) system tracks the location and position of a controller using image sensors on a headset and a controller. The headset and controller provide a first and second view of a user's environment. Using its camera, the headset generates a map of the environment and identifies its location within it. Based headset's location, the VR system generates a simulated world of the environment and displays it to the user. The headset also estimates the location of the controller. Based on the estimated location, the headset sends a portion of the map to the controller. The controller determines its pose using the portion of the map, the image sensors, and additional sensors. The controller sends its pose and an updated portion of the map to the headset. Based on the controller's pose and updated portion of the map, the VR system modifies the content displayed to the user.

Abstract: An online system receives a request for a video to be presented by the online system to a target user. The online system determines whether to insert secondary content into the video. For such a determination, the online system identifies a position in the video for inserting secondary content. Further, the online system determines a loss score and a gain score. The loss score measures a loss of interaction by the target user if the secondary content were inserted. The gain score includes a monetary compensation to be received by the online system for inserting the secondary content at the identified position. The online system compares the loss score and the gain score. Based on the gain score offsetting the loss score, the online systems modifies the video by inserting the secondary content at the identified position and provides the modified video for display to the target user.
