<p>Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for identifying a query for selected content. In one aspect, a method includes receiving gesture data specifying a user gesture interacting with a portion of displayed content. A subset of the content is identified based on the gesture data. A set of candidate search queries is identified based on the subset of the content. A likelihood score is determined for each candidate search query. The likelihood score for a candidate search query indicates a likelihood that the candidate search query is an intended search query specified by the user gesture. The likelihood score for each candidate search query is adjusted using a normalization factor. The normalization factor can be based on a number of characters included in the candidate search query. One or more of the candidate search queries are selected based on the adjusted likelihood scores.</p> |
