Abstract: A computer-implemented method to determine a rating of an item is described. At least one user review with textual information relating to the item is collected. A rating for at least one sentence of the textual information is calculated. An overall rating for the item is determined based on the calculated rating for the at least one sentence of the textual information.

Abstract: Techniques for identifying suspicious applications are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for identifying suspicious applications comprising determining one or more clusters of applications in an identified category of applications based on requested permissions of each of two or more applications in each of the one or more clusters of applications, determining a center application of each of the one or more clusters, and determining, using at least one computer processor, a similarity score for an application being evaluated based at least in part on a distance between the application being evaluated and the center application of a closest cluster of the one or more clusters.

Abstract: Power management systems and methods are presented. In one embodiment, implementation of a method for context specific power management of a resource, comprises: defining a context within which a resource operates, wherein the context is defined by one or more parameters; tracking a usage history of the resource operating within the context to determine passive user feedback related to a plurality of timeout values; and determining a timeout value for a current operation of the resource within the context based on the usage history.

Abstract: A computer-implemented method for diagnosing a network configuration of a computing device is described. A test network configuration is captured. A test network signature is generated from the test network configuration. A label is assigned to the test network signature. A determination is made as to whether the test network signature is labeled as an unsuccessful network signature. If the test network signature is labeled unsuccessful, one or more procedures to change the label are generated.

Abstract: A computer-implemented method for monitoring a mobile-computing device using geo-location information is disclosed. The method may include a learning phase. During the learning phase, a user may be located within a first range of physical locations during a recurring time period. The method may include generating a location profile for a mobile-computing device of the user and receiving a device-monitoring policy for the mobile-computing device from an administrator. The location profile may correlate the first range of physical locations with the recurring time period. The method may further include detecting, after the learning phase, that the mobile-computing device is outside the first range of physical locations during a first instance of the recurring time period. The method may also include implementing the device-monitoring policy after detecting that the mobile-computing device is outside the first range of physical locations during the first instance of the recurring time period.

Abstract: A method according to the invention includes determining a PHY layer model for a single interferer in an 802.11 wireless network responsive to an input of measured pair wise of at least one of a delivery ratio and received signal strength RSSI values in the 802.11 wireless network; ascertaining a deferral probability for a given node in the network in the presence of multiple interferers in a MAC layer model of the 802.11 network responsive to the determining step in the PHY layer model; and deriving from the ascertaining step at least one of sending capacity in the presence of multiple interferers, packet collision probability in the presence of multiple interferers and available capacity in a given link for a corresponding link delivery ratio.
