Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating real-time search results. In one aspect, a method includes receiving a search query from a client; determining that real time search results should be included in a user interface document responsive to the search query; generating the user interface document, including client software to cause the client to present real time search results for the query; and sending the user interface document to the client.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for ranking search results. One of the methods includes identifying one or more sessions for a query and associating watch times of the respective resources watched in the sessions with the query. One or more watch time signals are calculated for a first resource and the query based on the watch times associated with the query. A first search result responsive to the query is obtained, wherein the first search result identifies the first resource and has an associated score S. A new score S? is calculated based on a least S and a watch time function, the watch time function being a function of the one or more watch time signals. The new score S? is provided to a process for ranking search results including the first search result.

Abstract: Computers and methods are provided for receiving a search request sent by a computer associated with a user. A set of documents comprising a plurality of documents that satisfy the search request is identified. At least some documents in the plurality of documents have previously been annotated by at least one user of a plurality of users. A response to the search request is sent. The response includes a ranked set of links to at least some of the plurality of documents that satisfy the search request. At least some of the links are to documents that have previously been annotated by at least one user of the plurality of users. The response is associated with instructions to display one or more corresponding annotations for at least some of the links to documents that have previously been annotated by at least one user of the plurality of users. The response is further associated with instructions to display a filter selector including one or more filter options to reduce the identified set of documents.

Abstract: Contextually relevant pieces of alternative content, including advertisements, are selected for display with requested content based on documents or other second content sources that are referenced by or in the requested content.

Abstract: Methods, systems, and media for ranking content items using topics are provided. In some embodiments, a method for ranking video content is provided, comprising: receiving a search query; generating a plurality of search results in response to the search query; determining one or more entity types associated with a content class within the plurality of search results; determining whether the search query is a query for content belonging to the content class based on a plurality of criterion that includes: (i) determining whether at least one of the plurality of search results is associated with the one or more determined entity types and (ii) determining whether entities shared between the plurality of search results include the one or more determined entity types; and in response to determining that the plurality of criterion have been met, promoting at least one search result of the plurality of search results belonging to the content class.

Abstract: Implementations of the present disclosure include actions of receiving authoritative user data, the authoritative user data associating one or more queries with one or more authoritative users, processing the authoritative user data to identify one or more trigger queries, each trigger query including a query that, if received, triggers a display of one or more authoritative users in response, and storing the one or more trigger queries in a trigger queries database, each trigger query being associated with a first set of authoritative users, each authoritative user in the first set of authoritative users being associated with a first score relating to a particular trigger query.

Abstract: A method, system, and graphical user interface for improved web searching via user-specified annotations are disclosed. One aspect of the invention involves a graphical user interface on a computer that includes a ranked set of links responsive to a search request by a user. At least some of the links are to documents that have not previously been annotated by the user and at least some of the links are to documents that have previously been annotated by the user. The graphical user interface also includes one or more corresponding annotations previously created based on the user's input for at least some of the links to documents that have previously been annotated by the user.

Abstract: Contextually relevant pieces of alternative content, including advertisements, are selected for display with requested content based on documents or other second content sources that are referenced by or in the requested content.

Abstract: A method includes, receiving social network information of a user. The received social network information represents social graph data of the user and social network interactions of the user. The method also includes determining one or more subjects from content of the social graph data of the user and the interactions of the user. The method also includes identifying an initial collection of one or more individuals prominent in the one or more subjects from one or more measures of potential prominence provided by social network information of the individuals. The method also includes enhancing the initial collection of one or more prominent individuals to include additional prominent individuals. The method also includes providing a list of selectable entries to the user that includes each of the identified and additional prominent individuals.

Abstract: Methods, systems, and graphical user interfaces for improved searching via user specified ratings are disclosed. A rating icon for a document in a group of documents is provided. A user rates the document in the group of documents by performing a selection operation on the rating icon. A user-specific rating for the document is generated based on the user rating. A search request is received from a user. A plurality of documents that satisfy the search request are identified (including a first respective document which not previously been rated by the user but is in the group of documents that included the rated document.) A response to the search request is sent. The response includes instructions to display a ranked set of links to at least some of the documents that satisfy the search request including a link to the first respective document displayed with the user-specific rating.
