A method, system, and article of manufacture for disambiguating ambiguous queries based on location information. The system receives a query and location information for where the query was transmitted. Business information is requested from a GPS service. Based on the business information, a plurality of item categories are constrained to an item category related to the business information that satisfies the query. The constrained item category is sent to the user. The system may detect the absence of an item category related to the business information that satisfies the query, and may then determine one or more item category that does not meet the query but is related to the business information, to provide to the user. Other information related to the transmission of the query, such as the type of device, background audio, and the activity of the user, may used to constrain the plurality of item categories.
