  • Patent number: 10769677
    Abstract: A real-time messaging platform allows advertiser accounts to pay to insert candidate messages into the message streams requested by account holders. To accommodate multiple advertisers, the messaging platform controls an auction process that determines which candidate messages are selected for inclusion in a requested account holder's message stream. Selection is based on a bid for the candidate message, the message stream that is requested, and a variety of other factors that vary depending upon the implementation. The process for selection of candidate messages generally includes the following steps, though any given step may be omitted or combined into another step in a different implementation: targeting, filtering, prediction, ranking, and selection.

  • Patent number: 10089393
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media are provided. An example method includes receiving user input in a control, for example, one associated with a search engine. The user input includes a series of input characters that when completed would form a completed user request. The method further includes, while receiving the user input, evaluating the characters to identify completions for the completed request. The method further includes identifying, by one or more processors, a content item associated with the one or more completions and identifying display data associated with the content item for transmission to the user along with one or more completions in response to receiving the user input.

  • Patent number: 8504437
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media are provided. One example method includes receiving a textual input that forms a part of a user request, the textual input in the form of a prefix that when complete constitutes the request. The method further includes identifying completions based on the prefix, determining one or more content items associated with each completion, computing initial scores including a score for each content item-completion pair including determining a likelihood that a given completion represents the request and a quality of the content item as compared to the completion, computing final scores including scores for each prefix-content item pair using the initial scores, computing a bid for each content item, running an auction to select a content item based on the bids and final scores, and identifying display data associated with the selected content item.
