Abstract: In one aspect, a method includes receiving a query, identifying search results in response to the query, grouping the search results into one or more clusters, identifying similarities across the one or more clusters, determining a related topic associated with the query based on the similarities of the one or more clusters, determining a categories associated with the query, identifying supplemental information based on the related topic and the category, and providing the search results and the supplemental information for display in response to the query.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for automatic generation of news digests. One of the methods includes accessing a database storing news snapshots, each snapshot identifying a predetermined quantity of top news stories for a period of time, each of the top news stories in a particular snapshot for a particular period of time ranked according to an importance score that measures the importance of the news story relative to other news stories for the particular period of time, determining a digest time period, determining, for the digest time period, all of the snapshots with periods of time included in the digest time period, generating, from the top news stories in the determined snapshots, a digest ranking of digest news stories, and providing, to a user device, data identifying one or more of the digest news stories for presentation according to the digest ranking.

Abstract: The disclosure includes a system and method configured for resharing content items. The system includes a processor and memory storing instructions that, when executed, cause the system to: receive one or more social-content items that contain one or more first links; determine whether the one or more social-content items are related to a news-story cluster (including one or more news-story items) based on the one or more first links, the news-story cluster including one or more second links; responsive to determining that the one or more social-content items are related to the news-story cluster, associate the one or more social-content items with the news-story cluster; rank the one or more social-content items; and generate a resharing content item including the one or more ranked social-content items.
