摘要： A method performed by one or more computer systems coupled to a packet-based network to determine the location of a mobile device comprises receiving a set of input signals associated with the mobile device from the packet-based network. The set of input signals include a plurality of location components and context information. The method further comprises determining whether the set of input signals include a pair of latitude/longitude coordinates, and determining whether the pair of latitude/longitude coordinates are valid using a set of criteria. The method further comprises defining at least some of the set of criteria using historical data associated with a plurality of mobile devices communicating with the packet-based network. The method further comprises deriving the location of the mobile device using one or more other location components of the plurality of location components and the context information, in response to the pair of latitude/longitude coordinates being marked as invalid.

摘要： The present disclosure provides method and system to facilitate definition, tuning and visualization of a geo-fence at a computer system. The method comprises receiving an application program interface (API) call from the computer system, and in response to the API call, enabling the computer system to display a user interface (UI) on a display screen of the second computer system. The UI includes a first region and a second region, the first region including a plurality of screen areas for receiving input parameters for defining the geo-fence via a user input device of the computer system, and a second region is configured to display the geo-fence over a map of a geographical region around a location specified in the input parameters. The method further comprises, in response to receiving user inputs in the second region, generating the geo-fence based on the input parameters and mobile device events data stored in an electronic storage. The method further comprises causing the geo-fence to be displayed over the map in the second region of the UI.

摘要： A method of delivering location-based information comprises receiving a request including a location indicator from a packet-based network and translating the location indicator into a probabilistic representation of one or more possible locations of a mobile user based on historical data collected from mobile devices. By generating the probabilistic user location representation, the method can be used to deal with the inherent uncertainty in user location data, particularly in a mobile world. In some embodiments, this is done by using validation, context analysis, creation of consistent groups, and probability allocation procedures. Location-based document retrieval can be enabled using the probabilistic user location representation. In certain embodiments, IP regions for respective IP addresses are derived from ad requests made over a certain period of time, and the IP regions are used to translate location indicators of subsequent ad requests into probabilistic representations of possible locations of mobile users.

摘要： A geographic document retrieval method (GDR) can be executed by a computer system to index, retrieve and rank geographical documents. Textual and spatial attributes of geographical documents are indexed separately using inverted index and spatial index, respectively. Spatial attributes of a document are represented as one or more contiguously closed regions of arbitrary shapes. Upon receiving an input query carrying a geographic representation of a location using arbitrary regions, the GDR method retrieves one or more documents by executing an overlap test between arbitrary regions from the query and the arbitrary regions associated with the documents.
