Abstract: Methods and apparatus related to determining a triggering event of a user, selecting media relevant to the triggering event, and providing the selected media to the user. Some implementations are directed to methods and apparatus for determining a past event of the user that is indicative of past interaction of the user with one or more past entities and the triggering event may be determined to be associated with the past event. The media selected to provide to the user may contain media that includes the one or more past entities associated with the past event and the media may be provided to the user in response to the triggering event.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing contextual information for a displayed resource. In one aspect, a method includes receiving, from a user device, a query-independent request for contextual information relevant to an active resource displayed in an application environment on the user device, identifying multiple search items from the content in the resource, determining a relevance score for each of the multiple search items, selecting one or more of the multiple search items based on the relevance scores, and providing, to the user device for each of the selected one or more multiple search items, a respective contextual user interface element for display with the active resource, where each contextual user interface element includes contextual information regarding the respective search item.

Abstract: Methods and apparatus for providing travel-related information for a location to a user based on activity indications of the user that are related to the location. The location may be determined based on a set of one or more related activity indications and a travel-related score may be determined for the location that is indicative of likelihood that the user has interest in travelling to the location. The user may be provided the travel-related information for the location based on the travel-related score.

Abstract: In one example, a computing system includes at least one processor, a communication unit, and a predictive knowledge system. The predictive knowledge system is operable by the at least one processor to determine, based at least in part on the current location of the computing device, a particular geographic region from a plurality of defined geographic regions, the particular geographic region including the current location of the computing device, determine, based on an aggregated web access history for a plurality of computing devices, a content source associated with the particular geographic region, receive, from the content source, content designated for use by the predictive knowledge system, and send, via the communication unit and to the computing device, at least a portion of the content.

Abstract: In general, this disclosure is directed to techniques for outputting, by a computing device and for display at a display component that is operatively coupled to the computing device, a graphical user interface of an application. The computing device determines context data from content included in the graphical user interface. The computing device further determines, based at least in part on the context data, an indication of assistance that is contextually related to the content included in the graphical user interface. The computing device outputs the indication of the assistance.

Abstract: This specification relates to presenting image search results. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of receiving an image query, the image query being a query for image search results; receiving ranked image search results responsive to the image query, the image search results each including an identification of a corresponding image resource; generating a similarity matrix for images identified by the image search results; generating a hierarchical grouping of the images using the similarity matrix; identifying a canonical image for each group in the hierarchical grouping using a ranking measure; and presenting a visual representation of the image search results based on the hierarchical grouping and the identified canonical images.

Abstract: The present disclosure relates to the identification of video content. In one aspect, a method includes generating a query based on bibliographic data. The method also includes obtaining a collection of resources responsive to the query, wherein one or more of the resources include text and video content. The method further includes calculating occurrence scores for the resources. A particular occurrence score for a particular resource is based at least in part on the bibliographic data matching text included in the particular resource and the text being associated with video content. The method further includes selecting one or more resources as including video content identified by the bibliographic data using the occurrence scores. The method further includes storing data associating the selected resources with the bibliographic data.
