摘要： The disclosed technology includes system and method for discovering key places for a mobile device based on historical location data associated with the mobile device. The key places are discovered by mapping the historical location data into predefined land areas in a geographical region, aggregating the historical location data into time interval sessions, selecting a first set of the predefined areas based on density of location data in each of the predefined land areas, and filtering the first set of the predefined areas to obtain the key places. The key places are used to estimate one or more travel routes routinely taken by a user of the mobile device, and to build an association database, where one or more billboards and/or points of interests near the travel routes are associated with the mobile device or its user. Information documents for delivering to the mobile device are selected based at least on data in the association database.

摘要： A mobile device running a software application is configured to provide initial location data to a server when it is first turned on, or achieves a predetermined movement status. The server determines, based on the initial location data, geo data including a set of areas of interest (AOIs) near the mobile device and a region including the set of AOIs, and provides the geo data to the mobile device. The mobile device is further configured to track its locations when the mobile device is within any of the set of AOIs and to provide the tracked locations to the server. The mobile device is further configured to track its movement status after it has been outside the region, and, in response to a predetermined movement status being detected for a predetermined amount of time, obtain updated geo data including a new region and a new set of AOIs from the server. The software application enables efficient tracking of mobile device locations and reduces power consumption.

摘要： The present disclosure provides methods and systems that utilize mobile device location events and machine learning and generate predicative classification/regression model for lookalike prediction. Location related features, together with other user level information, are extracted, transformed and used as model feature input, and a client specified list of mobile devices or their associated users are used as prediction target. This system makes efficient use of different types of location events and thus offers improved scale and performance. It also enjoys many benefits offered by a machine learning platform, such as automatic adaptation to different lists of seed lists, addition of new features and changes in data statistical properties.

摘要： A system coupled to a packet-based network is configured to generate geo-blocks based on geo data related to real-world objects including transportation routes and natural boundaries in a geographical area such that each of the geo-blocks corresponds to a geographical region within the geographical area and has at least one border defined by a real-world object. The system is further configured to determine a performance measure with respect to a point of interest (POI) for each of a set of geo-blocks, and to select one or more geo-blocks each having a performance measure above a threshold from the set of geo-blocks to form a geo-fence for the POI. The threshold is adjustable based on a pacing status of an information campaign associated with the POI.

摘要： A system coupled to a packet-based network is configured to predict the locations of mobile devices that have communicated with the packet-based network. The system includes a request processor configured to detect location events associated with mobile devices communicating with the packet-based network, each location event corresponding to a time stamp and identifying a geo-place in a geo database. The geo-places include geo-blocks and geo-fences. The system further comprises a location prediction subsystem configured to construct first feature space using first location events and second feature space using second location events, and to extract a set of labels from third location events. The location prediction subsystem is further configured to train a prediction model using the first feature space and the set of labels, and to apply the prediction model to the second feature space to obtain prediction results.

摘要： A system for processing information requests associated with mobile devices comprises an information server configured to build a search query for an information request based on the location features and other data therein and to search an information database for matching information documents. The matching information documents including information documents having different types of performance measure, including a first document using an impression-based performance measure, a second document using a click/call-based performance measure and a third document using an off-line site-visit-based performance measure. The information server is further configured rank the matching documents based on their respective performance measures and to select a matching document based on their respective rankings. The information server is further configured to generate a projected probability of an off-line site visit in response to the second document being selected to fulfill the each request and impressed on an associated mobile device, and to adjust a budget of the second document based on the projected probability.

摘要： A map-based system and method allow an operator of a computer system to visualize real-time events of mobile users entering, staying within, and exiting geographic regions of interest. The method comprises receiving a first request for document from the packet-based network, the first request including a first plurality of parameters associated with a first mobile device, and determining whether the first plurality of parameters indicate a first real-time location-based event of the mobile device being in proximity of a geographic location of a first business. In response to the first real-time location-based event being determined, the method updates aggregated historical/statistical data including increasing one or more counts of location-based events associated with the first business over one or more periods of time, and transmit information associated with the first real-time location-based event to one or more second computer systems in the packet-based network, the information enabling the one or more second computer systems to visualize the first real-time location-based event together with other real-time location-based events on one or more display devices.
