Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer-readable storage medium, including a method for ranking content using location-based query log analysis. The method comprises: identifying a region defining an area of interest including identifying a plurality of content items that are associated with the region; evaluating query logs associated with users that submitted queries associated with the region to determine a ranking associated with the plurality of content items; receiving a request for content associated with the region; and providing one or more of the content items based at least in part on the ranking.

Abstract: Systems and methods for determining the geographic location of a user based on limited and ambiguous information available from the user's mobile electronic communication device are provided. In an embodiment, a computer-based system estimates a device's physical location based on partial identification information collected from the device such as the local area code and cell identification number, and numerous non-locational attributes. When the system determines that the collected information from the device corresponds to more than one single geographic location the system may use additional techniques of iterative disambiguation and filtering to determine a predicted location. Additional techniques may be used to increase the confidence level of the predicted location.

Abstract: Systems and methods for estimating the minimum geographic coverage of a wireless base station. In an embodiment, the present invention estimates coverage by (1) receiving real-time wireless base station information from the mobile device; (2) extracting a set of location points and system specific information based on the real-time wireless base station information; (3) determining a coverage area based on the set of location points and the system specific information; (4) adjusting for errors based on various factors (5) storing the determined coverage area.

Abstract: A wireless base station allows a mobile device to communicate with a wireless network. An estimate of the location of the wireless base station may allow a location based service to determine the location of a mobile device. In an embodiment, location may be estimated using a collection of data samples obtained from a mobile device. These data samples may contain carrier related timing information, for example GSM (Global System for Mobile Communications) timing information and received signal strength indication (RSSI). Data from the GSM timing information and RSSI may be analyzed to estimate a distance of a mobile device from a wireless base station. In another embodiment, a centroid of the data samples is computed. The centroid may then be used to estimate the direction of a cell phone tower relative to the centroid. In this way, using an estimate of distance and direction, location of wireless base station may be estimated.

Abstract: A method and system for accuracy analysis of wireless base station location is provided. In one embodiment, data from a set of mobile devices using a wireless base station is collected. A location of a wireless base station is estimated based on locations of the mobile devices (i.e. points) in the collected set. To provide a more accurate location estimation for the wireless base station, the estimated location is analyzed for accuracy based on the collected data. A confidence score is calculated using a weight function with weights for the collected data based on factors, such as, collection size, platform types of the mobile devices, quality, temporal diversity and/or spatial diversity of points corresponding to the mobile devices, etc. An estimated location of the wireless base station may be adjusted based on the calculated confidence score. An estimated coverage region of the wireless base station may be also estimated and adjusted.
