Abstract: A method and system for providing an answer to a subscription-based query service. The method includes acquiring context information and evidence information from one or more electronic devices based on a query. One or more belief values are assigned based on the evidence information and the context information. The belief values are aggregated for determining a score for competing hypotheses using a probabilistic model. Sufficiency of hypotheses is determined based on statistical significance for potential answer information to the query.

Abstract: In one embodiment, a monitoring method is described. The method includes detecting a set of contextual information by a monitoring device, and retrieving from the monitoring device a particular compliance query that adapts to the detected contextual information from one or more compliance queries.

Abstract: Methods, systems, and computer readable media for social grouping are provided to perform social grouping of a user's contacts based on the user's interactions with the contacts. A set of attributes associated with interactions between a user and a set of contacts may be determined by a first device. The set of attributes associated with the interactions may be related to the first device. The set of contacts may be organized into a set of groups based on the set of attributes.

Abstract: Binary motion events are detected by individual motion sensors placed in a physical environment. The motions events are transmitted to a cluster leader, each motion detector being a cluster leader of immediately spatially adjacent motion sensors. Movements of objects are detected by the cluster leaders according to the motion events. The movements are transmitted to supercluster leaders, each motion detector being a supercluster leader of immediately spatially adjacent motion clusters of sensors. Activities of the objects are detected by the supercluster leaders, and actions of the objects are detected according to the activities.
