Abstract: Aspects of the disclosure provide for the determining whether to assign a driver to a trip. For instance, a route for a trip between a pickup location and a destination location for a passenger may be determined. Branch routes for the route may be determined based on one or more lane changes of the route. A probability of following each determined branch route may be determined. A probability of requiring assistance for each determined branch route may be determined. Whether to assign a driver to the trip may be determined based on the probabilities for each determined branch route. A vehicle of a fleet of vehicles may be assigned to the trip based on the determine of whether to assign a driver.

Abstract: A computer-implemented method is disclosed. The method includes receiving from a remote device a search query, generating a plurality of different category-directed result sets for the search query, determining an order for the plurality of category-directed result sets based on the search query, and transmitting the plurality of category-directed result sets to the remote device, in a manner that the result sets are to be displayed in the remote device in the determined order.

Abstract: Methods, systems and apparatus for identifying modified images based on seed images that are known to be modified images. In an aspect, a method includes accessing data identifying a set of first seed images; for each first seed image, determining a respective first set of similar images from images in an image corpus, each similar image having a visual similarity score that is a measure of visual similarity of the similar image to the first seed image based on the image content of the similar image and the first seed image that satisfies a first seed image similarity threshold; and for each similar image in each respective first set of similar images, attributing to the similar image signal data of each first seed image for which the similar image has a respective visual similarity score satisfying the first seed image similarity threshold.

Abstract: Methods, systems, and apparatus for identifying landing pages for images. In one aspect, a method includes, for each image of a plurality of images, identifying web pages that each include the image, and, for each of the web pages, receiving a web score generated by a ranking algorithm. The web page having a web score indicating a highest importance relative to other web pages is selected, sets of similar images are determined from the images included in the selected web pages, and each set of similar images includes different images. For each set of similar images, an image is selected based on the selected web page that includes the selected image having a highest web score of the set, and the selected web page that includes the selected image is identified as a landing page for an image search result.

Abstract: Methods, systems, and apparatus, including computer program products, for selectively presenting search results responsive to search query suggestions. In one aspect includes receiving a partial search query including one or more characters; generating a first query suggestion based on the partial search query; determining whether the first query suggestion meets a filtering criterion, where the filtering criterion is a criterion specifying one or more filtering criterion topics against which the first query suggestion is evaluated independent of search results responsive to the first query suggestion; providing the first query suggestion; and in response to determining that the first query suggestion meets the filtering criterion, preventing a first set of one or more images responsive to the first query suggestion from being presented to a user.

Abstract: Methods, and systems, including computer programs encoded on computer-readable mediums, including a method for determining codomain relationship measures between domains pairs. The method includes accessing domain data specifying first and second domains; for each first domain: determining a total number of image links on web pages on the first domain, each image link being a link to an image on a second domain; identifying second domains hosting images to which image links on web pages on the first domain link; for each second domain: determining a number of image links from web pages on the first domain linking to images on the second domain; determining a codomain relationship measure for the first and second domain based on the number of image links from web pages on the first domain linking to images on the second domain and the total number of image links on web pages on the first domain.

Abstract: A computer-implemented method is disclosed. The method includes receiving from a remote device a search query, generating a local result set and one or more non-local result sets for the search query, determining a display location for the local result set relative to the non-local result set based on a position of the search query in a local relevance indicium.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for processing image endorsements. In one aspect, a method includes receiving a search query from a user device of a user that belongs to a social affinity group; receiving image search results responsive to the search query, each image search result referencing a corresponding image resource and including a representative image of the image resource; identifying representative images of the image search results that each have an endorsement association with one or more of the users identified by the social affinity group; generating annotation data describing the endorsement association with at least one of the users identified by the social affinity group; and providing the annotation data to a user device for presentation with the representative image.
