A system and method are provided for processing a request for crowd data for a large geographic area. In one embodiment, a central system, which includes one or more servers, operates to obtain current locations for users of mobile devices and form crowds of three or more users based on the current locations of the users. In order to provide access to crowd data for crowds for a large geographic area, the central system receives a request for crowd data from a requesting device, establishes a bounding region for the request, and identifies one or more starting points within the bounding region for the request. Crowds are identified, crowd data for the crowds is generated, and the crowd data is returned to the requesting device in an iterative manner for a series of two or more outwardly radiating, concentric geographic regions centered at the one or more starting points.

A system and method are provided for maintaining a historical record of anonymized user profile data for mobile device users. In one embodiment, a central system, which includes one or more servers, operates to obtain current locations and user profiles for users of mobile devices. The central system processes the current locations and the user profiles of the users over time to maintain a historical record of anonymized user profile data by location. By anonymizing the user data, privacy of the users of the mobile devices is maintained. The central system may then use the historical record of anonymized user profile data to respond to historical requests. The historical requests may be made by users of the mobile devices, subscribers, and/or third party services.

Systems and methods are disclosed for forming crowds of users based on wireless contexts of corresponding mobile devices of the users. In general, wireless contexts of mobile devices of a number of users are obtained. For each mobile device, the wireless context of the mobile device includes a wireless Personal Area Network (PAN) context of the mobile device, a wireless Local Area Network (LAN) context of the mobile device, or both. The wireless contexts of the mobile devices of the users are then utilized to form crowds of users. More specifically, in one embodiment, users of mobile devices having sufficiently similar wireless contexts are determined to be in the same crowd of users.

Systems and methods are disclosed for creating a user profile for a subject user based on historical aggregate profile data for locations at which the subject user was previously located. In one embodiment, one or more location and time period pairs are determined for the subject user, each defining a previous location of the subject user and a time period during which the subject user was at the location. For a plurality of location and time period pairs, a plurality of historical aggregate profiles for a corresponding plurality of sub-bands within the time period defined by each location and time period pair in the plurality of location and time period pairs is obtained. A user profile for the subject user is created based on the plurality of historical aggregate profiles for the corresponding plurality of sub-bands based on relevancy ratings for the plurality of sub-bands.

Systems and methods are disclosed for monitoring hashtags in micro-blog posts, or status updates, from users to provide one or more crowd-based features. In one embodiment, a micro-blog post of a user in a crowd of users is obtained. The crowd of users is a group of users within a predefined spatial proximity to one another. A hashtag in the micro-blog post is then obtained, and a crowd-based feature is provided based on the hashtag.

Contiguous location based user networks are disclosed herein. A method includes receiving an identification of an area of interest associated with a user of, and transmitting the identification of the area of interest to a server. The method includes determining a location of the user device and transmitting the location to the server. The method includes receiving information identifying a proximity group comprising the user and a plurality of other users. The proximity group includes least one other user being within a proximate area of the location of the user device and having an area of interest corresponding to the area of interest of the user. The proximate area corresponds to a second geographic region smaller than the area of interest. The proximity group further comprising at least one additional other user identified as a neighbor of each of the user and the at least one other user.

Systems and methods are disclosed for following status updates sent by users in crowds of users. In one embodiment, a requestor is enabled to follow status updates sent by users in a crowd of users even after the users have dispersed from the crowd. More specifically, in one embodiment, a requestor selects a crowd to follow. Subsequently, after one or more users have left the crowd, status updates from the users are obtained and sent to the requestor. In another embodiment, a requestor selects a crowd to follow. Subsequently, after some or all of the users in the crowd have dispersed, status updates from users in new crowds in which those users are located are obtained and sent to the requestor. In another embodiment, a requestor is enabled to follow a user such that the requestor receives status updates from crowds of users in which the user is located.

Systems and methods are disclosed in which a location update for a user is utilized as a location update for the user and one or more additional users that have been location-synchronized to the user. In general, a location update is received for a first user. One or more second users that have been location-synchronized to the first user are then identified. A location reported by the location update for the first user is recorded, or stored, as a current location of the first user and a current location of each of the one or more second users that have been location-synchronized to the first user. A location-based service, such as a social location-based service, may then be provided based on the current locations of the first and one or more second users.

摘要:
Systems and methods for generating a social topography map based on user affinity concentrations are disclosed. In general, locations and aggregate profiles are obtained for a number of crowds of users that are relevant to a geographic bounding region for a desired social topography map. Each aggregate profile includes information regarding an affinity between a corresponding crowd and a defined user profile. The defined user profile may be a user profile of a requesting user, or a select subset thereof, or a target user profile. Social topography data for the desired geographic bounding region is then generated based on the locations and aggregate profiles of the relevant crowds. The social topography data defines user affinity concentrations across the desired geographic bounding region. A social topography map may then be generated and presented to a requesting user based on the social topography data generated for the desired geographic bounding region.
