Abstract: Location graph-based derivation of user attributes. Location data associated with a user, such as a current and/or past location at which the user has been, is received. A user attribute data associated with the location data is determined and used to update a user profile associated with the user.

Abstract: Systems and methods including a mobile device determining the coordinates of its location using a location determination system, such as a global positioning system. A database stores the identifiers of cells representative of predefined regions in a hierarchical grid system. A server computer or the mobile device converts the coordinates of the location to one or more cell identifiers at different grid resolution levels and searches the database to find a match between the cell identifiers representing the regions and the cell identifiers representing the location of the mobile device to determine one or more regions in which the mobile device is located. For example, the hierarchical grid system can be constructed in a longitude latitude space of location coordinates, with resolution levels aligned with decimal precision levels of the location coordinates; and the cell identifiers can be constructed from the digits of the longitude and latitude coordinates.

Abstract: Systems and methods including mobile devices determining their location using a location determination system, such as a global positioning system. A database stores the identifiers of cells representative of predefined regions in a hierarchical grid system. The location coordinates as function of time are converted to visitation patterns of the mobile devices to the predefined regions, based on converting the coordinates to cell identifiers and searching the database to find matches between the cell identifiers representing the regions and the cell identifiers representing the mobile device locations. For example, mobile devices having similar visitation patterns can be identified and divided into two groups; and information relevant to a region is transmitted to one of the group but not another. The visitation patterns of the two group after the transmission is identified and compared to measure a difference.
