Abstract: A computer-implemented method that includes for each geographic object of a geo-object set, identifying, using a computer, one or more geographic cells of a geographic mapping that each correspond to a geographic area proximate to at least a portion of a geometry of the geographic object and assigning a weighting value to each of the one or more geographic cells identified as corresponding to a geographic area proximate to at least a portion of a geometry of the geographic object such that the one or more geographic cells are associated with the geo-object.

Abstract: A method for performing a location search includes receiving a location search query, identifying one or more geographic feature documents that satisfy the location search query, ranking the identified geographic feature documents in accordance with scores that are based, at least in part, on corresponding address support scores, to produce a set of ranked documents, and providing results, in accordance with the ranked documents, that identify at least one geographic feature corresponding to at least one of the ranked documents. An address support score for an identified geographic feature document can be based on one or more of: a standalone support score and a template support score.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for detecting travel information. In one aspect, a method includes receiving a document; annotating detected entities in the document; generating one or more travel leg structures using the annotations, wherein generating the one or more travel leg structures includes determining that one or more annotations match a valid travel schedule; and generating an itinerary from the one or more travel leg structures.
