Location-aware query parsing for mobile voice search

Abstract

Mobile voice search provides users an easier way to search for information using voice from mobile devices. Most mobile search applications have access to the latitude/longitude coordinates of the device, which can be exploited to deliver location-specific search results. Geography and queries users submit are inextricably intertwined. In this paper we present the findings of a study on the spatial proximity of queried location and device location in a local search application. We then propose a location-aware query parsing model to parse queries into concepts that are necessary for high precision search.
