In general, in one aspect, a method includes receiving a query image, obtaining a set of text labels associated with the query image, each text label associated with a confidence score that the text label accurately describes a topic of the query image, selecting a first text label associated with the query image, the first text label having a highest confidence score among the set of text labels, selecting a subset of the set of text labels that have a confidence score greater than a confidence score threshold, obtaining search results responsive to the query image, and in response to at least one of the search results identifying a web page containing the first text label, sending data that causes a client device to display the subset of text labels with the search results.
