Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing actions of determining that one or more in-depth article search results are to be provided in response to a query, obtaining a topicality score for each in-depth article of a plurality of in-depth articles, each topicality score indicating a degree of relevance of a respective in-depth article to the query, obtaining a document score for each in-depth article of the plurality of in-depth article, each document score being based on a respective topicality score and a respective in-depth article score, selecting one or more in-depth articles from the plurality of in-depth articles based on respective document scores, and providing the one or more in-depth article search results for display, each in-depth article search result representing an in-depth article of the one or more in-depth articles.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for creating experiment content distribution campaigns (“experiment campaign”) and allocating content in accordance with the experiment campaign. In one aspect, a control campaign or an experiment campaign are selected as an available campaign for providing content in response to receiving a content request. The selection can be a probability constrained selection where the probability with which the experiment campaign is selected is specified as a portion of a total number of requests received during an experiment period for which the experiment campaign is available to provide content. Content is provided in response to the request, where the provided content being content corresponding to the selected campaign.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for information retrieval. In one aspect, a method includes receiving a search input including one or more search terms; determining whether the search input includes a particular token; in response to determining that the search input includes the particular token, determining whether the one or more search terms are associated with a particular social page; in response to determining that the one or more search terms are associated with the particular social page, providing the particular social page without providing search results.

Abstract: A system, method and computer program product for using delegation as a mechanism to manage business activity by taking on a shared identity. In some implementations, the system includes a user interface module for receiving input signals from and sending information to a user, a delegate authentication module and an identity translation module. The delegate authentication module is operable to determine that an individual user identity is authorized to act as a delegate for an organization having an identity on a network-based software application and generate a verification signal. The delegate authentication module is coupled to the user interface module to receive the input signals from the user. The identity translation module is operable to translate the input signals from the user to a format such that they appear to be from the identity of the organization.

Abstract: Systems and methods for determining and utilizing selection data are described. In one aspect, a system and method for determining an article containing at least one item associated with selection data, determining a path associated with the article containing the at least one item, and identifying at least one term associated with one or more of the at least one item based at least in part on the path is described. In another aspect, a system and method for determining a geographical location associated with an article based at least in part on selection data associated with the article, determining geographical locations associated with at least some items within a plurality of items based at least in part on selection data associated with the at least some items, and selecting at least one of the plurality of items to be presented on the article based at least in part on the geographical location associated with the article and the geographical location associated with the item is described.
