Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for ranking images using hover data. In one aspect, a method includes determining a click count and a hover count for an image and a search query pair. The click count specifies a number of times that an image search result that includes a representation of the image has been selected when provided in response to the search query. The hover count specifies a number of times that the representation of the image has been hovered over when the image search result has been provided in response to the search query. A quality measure for the image with respect to the search query is determined. The quality measure is based on the click count and the hover count. A ranking of the image is adjusted for the search query based on the quality measure for the image.

Ranking image search results using hover data

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for collecting and compiling information regarding search operations. In one aspect, a query log that stores search event data items for identifiers is accessed. A proper subset of the search event data items is identified, the proper subset of search event data items being search event data items for search events related to an image search. A proper subset of the identifiers is identified, the proper subset of identifiers being identifiers associated with a search event data item for a search event related to an image search. For each identifier of the proper subset of identifiers, an image search session data object is generated using the proper subset of search event data items.
