摘要： The claimed subject matter provides systems and/or methods that facilitate generating an inference about events that may not have yet been observed. Open-world modeling can be used to take a history of observation so as to understand trends over time in the revelation of previously unseen events, and to make inferences with subsets of data that new unseen events will be seen. Thus, inaccuracies associated with predictions generated from incomplete data sets can be mitigated. To yield such predictions, open-world submodels and closed-world submodels that do not allow for previously unseen events can be combined via a model mixture methodology, which fuses inferences from the open- and close-world models.

摘要： The claimed subject matter provides systems and/or methods that facilitate inferring probability distributions over the destinations and/or routes of a user, from observations about context and partial trajectories of a trip. Destinations of a trip are based on at least one of a prior and a likelihood based at least in part on the received input data. The destination estimator component can use one or more of a personal destinations prior, time of day and day of week, a ground cover prior, driving efficiency associated with candidate locations, and a trip time likelihood to probabilistically predict the destination. In addition, data gathered from a population about the likelihood of visiting previously unvisited locations and the spatial configuration of such locations may be used to enhance the predictions of destinations and routes.

摘要： Described are methods that utilize a geographic location technology (e.g., GPS) to determine user location data, and existing network-based websites (e.g., Internet websites) for searching and accessing data related to the location data such that the user context can be developed and stored. A location component is provided that determines location data of a wireless communications device of a user. A context component is provided that accesses context data based on the location data to define a context in which the device is located. Activities, goals, and overall context of a user can be inferred through statistical fusion of multiple sources of evidence. The context data is presented to the user via the wireless device such that the user can make decisions as to where to go, for example. User preferences can be accessed and applied to filter context data according to what the user desires to see and access.

摘要： The subject disclosure pertains to systems and methods for determining locations of mobile devices. In particular, a set of regions is defined based upon the relative strength of signals received from one or more base stations within the region. Each region has associated location information (e.g., latitude and longitude). The location of a mobile device can be determined by analyzing the strength of received signals, identifying base stations and generating an ordered list of base stations based upon signal strength. The ordered list can be compared to the set of regions to determine the region in which the mobile device is located. The location information for the retrieved region can be used to estimate the location of the mobile device.

摘要： A method, schema and computer system for a location service provides data structures that are extensible by allowing different types of location awareness applications to retrieve and deposit location data. The method includes providing an abstract location object arranged in a schema to enable servicing a received request for a logical location of an electronic endpoint; and arranging one or more location elements within the context of the abstract location object. The location elements are configured to act as peers relative to the logical location and each location element is configured to act as a proxy relative to any other location element within the abstract location object.

摘要： A user can be provided a variety of incentives to take a route that is different from a standard path in order to relieve path load balancing issues. Information on a primary path can be collected and analyzed to determine if it would be beneficial to encourage users to take an alternate path. If it is determined that users should be encouraged to take another path, then analysis of potential users can occur. A result of the user analysis can be used to select users that are offered to take the alternate path as well as an incentive offered to the user to encourage her to take the alternate path.

摘要： Routes can be produced based on safety characteristics of paths that are included in the route. Safety characteristics can include how susceptible an area surrounding a path is to crime as well as traffic data, such as how many automobile accidents take place on average. Various amounts of safety information can be gathered and a particular path can be assigned a safety score. Analysis can run on different path combinations that would take a user from a starting point to an intended destination. A route can be produced based on the safety score alone, such as a route with a lowest score, based on the safety score with other factors such as anticipated traffic, and the like.

摘要： An image background maintenance system and method for maintaining a background model of an image sequence by processing on multiple spatial scales. These multiple spatial scales include a pixel scale, a regional scale and a frame scale. The image sequence undergoes pixel processing that determines a current background model and provides an initial pixel assignment as either a background or a foreground pixel. Region processing further refines the initial pixel assignments by considering relationships between pixels and possibly reassigning pixels. Frame processing further refines the current background model by determining whether a substantial change has occurred in the actual background and, if so, providing a more accurate background model.
