Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for processing drawing-based search queries. In one aspect, a method includes receiving search request data specifying a search request, the search request comprising a drawing represented by a set of line strokes, each line stroke representing a trace of a moving input point; identifying line segments from the line strokes; comparing the identified line segments to reference line segments, each of the reference line segments representing a portion of a corresponding reference drawing; identifying a candidate reference drawing based on the comparison of the identified line segments with reference line segments; identifying a keyword for the candidate reference drawing, the keyword being a term determined to be relevant to a subject matter of the candidate reference drawing; and in response to receiving the search request, providing search results data specifying search results responsive to the keyword.
